Founding engineer, team lead, technical consultant, manager ────────────────────────────────────
Relocation: no, but some travel
Tech + skills: software/architecture design/development; performance-critical code, distributed systems; Rust, Node.JS, RoR, Python, Java etc; custom data structures, algorithms.
With a background as a founding engineer, team lead and manager, I bring the expertise and experience you need to go from concept to production. While I have worked in organisations ranging from tiny through huge, my forte is working in smaller teams with meaningful technical challenges, where I specialise in delivering robust high-performance minimal-dependency solutions that operate unattended for months and years. I have built teams from the ground up, creating productive and inviting teams with clear goals and well-functioning processes.
In short, my experience can be summarised as:
◆ 20 years as a programmer, developer and architect; ◆ 10 years in roles leading and mentoring teams and individuals; and ◆ 5+ years in 100% remote mode. I work best in small teams where communication paths are short, where there is—by necessity—minimal overhead and where responsibilities are clear. You are primarily concerned with what we can build together, and not with the technical details. While I am looking for interesting technical problems, you are looking for someone to take responsibility for the whole solution.I am open to discussing part-time contracts and/or non-standard arrangements.
My CV is available on request.

Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work, but I am open to work on any interesting project. I am a European software developer who has lived and worked on four continents. Now it's time to move on and so I am in the process to relocate to Africa.
I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.
I value good teamwork over fancy tech, and I don't shy away from working on legacy code. I am primarily motivated by solving problems, so let me help you solve your problems.
I am open to work for companies anywhere as long as the work can be done fully remote from Africa.
While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.
In addition, I want to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. I also sponsor children that otherwise can't afford to go to school (see my website). If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up your team.

I have built many apps on AWS and Google Cloud, including using Terraform for infra and Github Actions for CI/CD.
Right now, I have a side hustle bootstrapping Hot Page (https://hot.page) and releasing native HTML web components as part of my open source project HotFX (https://fx.hot.page).
Well-rounded Scala/Rust/Python dev, well-versed in data engineering, with deep knowledge of the internals of distributed datastores.

I help Series A-C startups navigate technical chaos and scaling challenges. After 7 years consulting both directly and through agencies (and decades of engineering work), I specialize in organizations experiencing transitions - post-funding growth, leadership changes, or strategic pivots.
What I actually do:
- Transform chaotic delivery through listening-first process design (I discover what YOUR team needs, whether that's Shape Up, incentive realignment, or custom approaches)
- Identify and fix incentive misalignments that sabotage delivery (saved one client $300k+ in unnecessary architecture changes)
- Secure AI tool adoption without the phantom package vulnerabilities most teams miss
- Bridge technical excellence with organizational transformation
My average engagement is ~6 months across 15+ clients.
Recent wins: - Delivered critical project 17% faster during company layoffs using Shape Up
- Established cross-team coordination that unblocked a multiyear replatforming effort
- Prevented costly microservices migration by identifying vendor's misaligned incentives
Technical foundation: Ruby/Rails, Elixir/Phoenix, comprehensive DevOps (AWS/Terraform/Docker), AI security expertise. But I'm hired for my ability to see why your technical initiatives keep failing and fix the root causes.
I thrive in chaos. If your organization is at an inflection point and needs someone who can deliver immediate technical value while building lasting capabilities, let's talk.

In the past, I've taught a number of scientists and students to code in python; I've led and managed a number of high-impact engineering teams of up to 12; and pioneered a number of no- and low-code solutions for stream processing, data model and query generation, form building, workflow systems, and front-end construction for a variety of industries, including those with strong regulatory requirements and complex business rules such as healthcare and fintech. >10% of all medicare applications and millions of individuals currently flow through pioneering no-code systems I conceived and built and have ran in production for over a decade.
More recently, I've built a no-code automated form-filler and a workflow engine for coordinating LLMs and other generative AI processes, and on top of this a platform for both minimizing hallucinations and working with documents that are far too large for existing context window inputs or outputs using a novel, patented process that I invented; and applied these tools to various contracted projects requiring analysis and and cross-checking of information and other forms of integrity across textual and video/audio corpus data in a variety of domains (fiction and non-fiction).
I am also an improvisational pianist, published poet, and I've created novel algorithms and tools for studying and composing both music and poetry, which I have given a talk on at a recent functional programming conference.
I have extensive experience working for and running startups, software consulting shops, with some mid-sized company engineering experience as well; these give me a unique insight into speaking with customers and internal stake-holders, translating between engineering and other departments, gathering requirements, aligning stake-holders across departments on a vision and attainable timeline, and architecting/building/taking ownership over significant internal and customer-facing areas of responsibility.
If any of the above seems like a match for you and your organization or project, don't hesitate to reach out.
vCISO & Cloud Security (AWS, ISO 27001, Risk Management)
I’m an independent security consultant with 20+ years in operations and cloud security, now running a remote-first vCISO practice from Spain. I focus on helping AWS-based startups and SMBs (50–250 employees) strengthen their security posture, meet compliance goals, and prepare for audits.
Services I provide:
* vCISO retainer ($5k/month) – security strategy, governance, board reporting
* AWS security architecture reviews – design and remediation guidance
* ISO 27001 gap analysis & roadmap – prep for certification
* Risk assessments (NIST CSF, ISO 27005, CIS Controls)
* Cloud security program build-outs
Who I work with:
* SaaS / Internet companies scaling quickly on AWS
* Startups seeking a pragmatic, fractional CISO instead of hiring full-time
If you’re looking for someone to build or improve your security program, align it with compliance frameworks, and work directly with leadership/engineering, I’d love to chat.

I am a Lead Infrastructure Engineer with 20+ years of experience.
Whether your team is stuck troubleshooting infra issues, needs extra hands on an infra-heavy project or is just lacking tech leadership on the DevOps topics, contact me and we'll figure it out.
I prefer to work along the existing engineering teams, mentoring or training them while working together on the real tasks. This is a very effective and also a flexible way to learn and as a bonus, some work gets done on the way.
I am located in EU (Estonia) and work remotely with occasional on-site visits.
The usual topics are various AWS services, Elastic Stack, Linux, wide range of troubleshooting, infrastructure as code, logging & monitoring, managing cloud costs, but I find it rewarding to venture into new areas together with the team.

Hi! I've been a fullstack developer since the early 2000s, doing both fullstack, backend, frontend, and occasionally mobile apps with web technologies.
I take great pride in delivering products that actually work, and I have a knack for making user-friendly UIs as well as developer-friendly APIs and good documentation.
I am a backend expert, having built and maintained mission critical, low latency and highly available systems for several companies over the last 10 years, in addition to over 20 total years of software development experience. I learn new things extremely quickly. AWS preferred but not required (I hold a variety of certs, available here: https://www.credly.com/users/jon-north.ad78f0c8)
You will like working with me because I:
* hold your goals as my priorities * communicate verbosely yet synthesize well * my rates are reasonable in exchange for the value I deliver * I guarantee I will get the job done Concrete examples:* built the streaming data architecture for realtime game player tracking information (all games, 50ms SLA) and game stats for one of the top 3 US sports leagues (can’t name drop!) using Redpanda/Kafka on Azure+Terraform, and implemented its developer portal using Gravitee to provide first class streaming API support and monetization. Also built, deployed and maintained their ask-a-question-get-a-true-answer AI bot to expose 20+ years of stats to natural language fan questions!
* Implemented a vector DB for one of the leading AI image hallucination platforms (millions of users) to provide an image similarity service.
* replatformed dozens of complex quant jobs to AWS Lambda for a startup hedge fund (~$1B AUM), vastly improving QoS and maintenance cost. Line 1 to platform-in-prod time 3 months, including refactoring for fit. This was mission critical cannot-fail stuff and required extensive proof of correctness.
* built a ~50 node, AWS, Dockerized, Terraform-deployed distributed system to provide realtime, transformed trade data from crypto exchanges to a Kafka pipeline and data lake (fodder for an analytics platform). Met 5000msec SLA across arbitrarily many exchanges and ticker symbols. Blue-green deployment for complete CICD safety. Cloudwatch metrics proved SLA was met and provided general system oversight.
* built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.

Willing to relocate: no, but willing to travel/visit. I'm flexible with working hours, I usually work with clients from either Western Europe or the USA.
I do dev/devops/security, usually for startups or scale-ups or other small orgs with limited resources, and I've been doing that for 15+ years. So, if you:
* Have a slow web application that’s often down?
* Want to improve security and don’t know where to start?
* Have a legacy system that needs to be replaced?
* Are considering an acquisition but not sure about the technical side?
I can help with that. For example, in the past I have:
* Massively improved performance and reliability for a data visualization platform.
* Led a large effort to improve security for a cybersecurity SaaS.
* Built a micropayments system for a prominent media startup.
* Rebuilt an aging e-learning platform from scratch for a GDPR compliance SaaS.
* Conducted technical due diligence for acquisitions.
