Every week I stumble upon websites of software companies who are just as good as their more famous competitors (or even better), but their marketing sucks, and that's why they never reach the hockey-stick growth phase -- they never find their starving crowd.
Or they have some traction but they don't know how to reach out to more potential customers at scale or what to even say to get them interested and book demos.
Needs some help with those things? Send me an email today.
Cheers,
Filip Stanojevic -- Copywriter, Email Marketer, GTM Engineer

I love solving complex problems and have 14 years of experience in Fin-Tech, Journalism, TV and Media, Health, Science, and more.
I've taken countless projects from 0 to 1 working with clients like JPMorgan Chase, Santander Bank, Rob Walling, Trello, Peter Diamandis, Syncthing, SimplyCredit and others. I'm experienced in Vue.js, Django, Phoenix framework, Quasar, just to name a few. I pick up new tech easily and like working on complex products.
I can help you with:
- Product Design: I help identify and solve the real problems your users face. Whether you're struggling with low engagement, confusing user flows, or a product that doesn't quite meet market needs, I dig deep into user pain points to design solutions that actually work. From ground-up product strategy to fixing specific friction points that are hurting your metrics. - Front-end Development: I can turn the design into a pixel perfect product. Being able to design and develop allows me to move at speeds otherwise impossible by cutting a lot of the steps otherwise needed. I take my work very seriously and put a lot of work into excellent communication, proper planning, and last but not least, properly understanding your product so that we can produce great results.

Hi HN! I'm a full-stack developer with a strong frontend focus - 10+ years of experience building fast, clean, and scalable web apps.
On the frontend, I work with React, Vue, and Svelte. On the backend, I've shipped systems using Go, Python, and Node (Nest.js, Django, FastAPI, etc). I enjoy working on thoughtful product design and efficient APIs just as much as hacking on UI.
Lately I've been freelancing through ainurhq.cloud, doing both client projects and internal tools. Some recent work includes:
● jsDelivr: contributed engineering support and improvements
● Radiabase: contributed to a CRM-style lead and sales management platform
● UniDeck: a no-code, plug-and-play dashboard builder with built-in integrations. Built from the ground up with my team at AinurHQ
I'm currently looking for freelance/contract roles (or possibly full-time) - ideally on a modern product team where I can contribute across the stack.
Feel free to reach out if you're building something interesting:

Tech stack:
· Languages: TypeScript, JavaScript, Go, Python

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.

Hey, I'm Tim, a senior fullstack developer from New York, now based in Mexico. I have more than 12 YoE on all kinds of web apps as well as mobile and server environments. I love backend and APIs, but I have a passion for pixel-perfect UIs and frontend magic. I have built many of my own projects from start to finish so I have learned a lot about good UX/UI, can choose the best technologies for the job, spot problems before they arrive and write solid tests. My prior career in journalism made me a great communicator and writer. I also enjoy devops and managing servers using Linux, Docker and Kubernetes. 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 have experience with data modeling for high throughput database activity and a strong understanding of which workloads and data access patterns are scalable and what datastore the data should reside in. I have a highly confident ability to lead a data / MLops project from start to finish. Hire me.
Core Skills:
● Cassandra (Data Modeling, Troubleshooting Performance And Operational Issues)
● Apache Iceberg (Scaling, Tuning, Self-Hosted Setup)
● Stream Processing At Scale: Kafka, Flink, Spark Streaming, Storm
● Custom-Crafted TF-IDF / Embeddings, Vector-Based Semantic Search, Deep Intent Recognition In Search Engine Queries
● Languages: Scala, Rust, Python, SQL (proficient), Golang (ramping up)
Other Skills: Airflow, Aerospike, DBT, Snowflake, Qdrant, Databricks/DeltaLake, BigQuery, Redshift, Hive, Kinesis, PrestoSQL/Trino, ClickHouse, gRPC, Airbyte, Terraform, CUDA, Reverse-Engineering Search Engine Technologies.
Educational Background: Computer Science.
Solid experience working remotely and working with teams that are distributed geographically. I typically work Pacific Time hours.

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.

Full-stack, Django-first. I ship MVPs and steady/modernize legacy systems. Integrations & data flows: Zapier apps/CLI, ERPs, billing, CRMs, webhooks/ETL. Collaborative by default, like writing docs. I can learn your domain fast.
Ex-integrations @ Zapier/Tesorio. Founder background, hands-on and available for short projects or ongoing work.
I have most experience mwith C# (web services, aspnet, razor, ...) also desktop apps (WinForms, WPF, Avalonia), JS/Typescript (mostly for gui, I enjoyed mithril and now SolidJS). I also did some c++ for various small integrations (for example some plugin for Godot, some ffmpeg. Last year I focused heavily on Rust, and created user space network bonding protocol, now audio intercom. I mostly worked with GPC 70% , AWS 20%, other (like Hetzner) 10%.
I like to make GUI/backends that makes sense, are easy to understand (test with users) and performant/fast. Also to last years, with minimum dependencies. I also have experience with live events setup for broadcast of events, have experience with networks.
I also did tons of remote support with people around the world, also know how to use this information to make better programs (or design...).
Looking for 20-100 hours per month.
Last year I started solo career and am now slowly building better references/page etc.
