Hi, I'm Christian! I'm a senior software engineer with 9 years of experience and I help teams deliver solutions on time. My focus is API development, integrations, and cloud infrastructure. My strengths include working with stakeholders across multiple business units, defining engineering best-practices, spearheading ambitious projects, and mentoring other engineers.
Who I am: An IT security professional with 15+ years of security testing and consulting experience.
What I do: Remote penetration testing for your website, web application, or IT infrastructure.
What you get: Comprehensive security testing and a detailed report, provided at a reasonable price.

Resume/CV/Email: https://valeatis.hr/
Full-stack web developer with 5+ years of experience. Specialize in developing comprehensive UI interfaces for platforms, fintech applications, and user management systems. Worked with small to medium-sized companies and served clients from the UK, Italy, and predominantly the USA. Experienced in greenfield projects, brownfield projects, rewrites, and legacy systems, working both independently and as part of collaborative teams to deliver high-quality solutions.
Looking for companies in the B2B/D2C e-commerce sector in niche markets.
I have more than 10 years of experience in the software and marketing aspects of B2B/B2C e-commerce (Europe & US). For the past 2 years, I took a deep dive into D2C as a Technical Co-Founder of a fragrance-related brand (https://yuma.gr), successfully positioning us in the premium market at the lowest cost possible, by developing the e-commerce and ERP platform in-house.
I can handle all aspects of e-commerce with a focus on growth. Examples include:
- Extensive Google & Facebook Ads automation at scale via their APIs
- Distributed bots for scraping millions of SKUs daily for dynamic pricing
- Deep & proven knowledge of e-commerce & ERP architecture & development
- Complex and custom-made solutions (e.g., in-house developed Klaviyo alternative)
- Creative approaches to streamlining internal operations
- Frontend performance & SEO micro-optimization
- Landing page optimization for conversions
I prefer long-term commitments and typically work on projects for 6 months to 1 year, as I treat each project as my own. Having developed my D2C brand to a technical level that now requires only maintenance and marketing, my schedule has become more flexible. I'm ready to help companies in different markets while expanding my skills and knowledge.

With my own in-house CNC manufacturing capabilities (milling, turning, plasma cutting) using state of the art industrial equipment, I am able to easily expedite prototypes for my clients.
I am well rounded with skills outside of mechanical engineering including experience in automation and control systems, robotics, software development, and more.
Current projects include developing engine dynamometer systems, including the required control systems and mechanical assemblies to accurately test racing engines: https://www.precisiondynotech.com/

Unicorn. I do branding [1], design, and full-stack JavaScript development. I built the Joystick JavaScript framework (full-stack [2]) and Push deployment service [3]. Recently shipped Parrot [4]. Currently preparing a CSS framework for SaaS apps for release [5].
Though I prefer my own tools to move fastest, I'm competent with and adaptable to any/all JavaScript + Node.js frameworks and tools (e.g., Next.js, Svelte, Vue, etc). Can also handle TypeScript if need be.
Looking to work with startups, entrepreneurs, and small teams (or VCs who need a sharp shooter who can deliver) who need help shipping product and features that work from day one, ASAP.
17+ years of experience running a small business/shipping software, so I don't need to be babysat—just set loose with a clear idea of what needs to be built and open lines of communication if/when I have questions.
Average time to brand, design, and ship a full-stack app is 3-6 months but I can move faster if you're willing/able to delegate 100%.

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.
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.
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 am also open to work for companies anywhere as long as the work can be done fully remote from Africa.
In addition, my plan to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. 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.

If you’re in-between companies or looking for an interesting freelance project, we might be a great fit.
Some freelance roles we’re currently seeking include:
- Product Design - Infrastructure / DevOps (pulumi/k8s) - Backend Engineering (node/typescript)
We build web3 developer tools and are most focused on solving the "schlep" types of problems that every team ends up building in house but shouldn't have to.
Building stuff in crypto today is really hard. Imagine if you wanted to put up a personal website and all you had to do was start by breaking ground to build a data center. Your personal page probably would not be that good, would it? Small teams can only focus on so many things; we want them to use center so they can focus on the details that truly matter and make products beautiful.
We want to eliminate all of these annoying, cumbersome, expensive problems that devs face so that they can build incredible user experiences that help people flourish and rise to the level of their ambition, without having to think about if their nodes are online or if their indexer is missing any data.
We started about 3 years ago and have finally started to find product market fit. We're looking to scale the engineering team so that we can finally bring our products to market.
Our investors include Founders Fund, Thrive Capital, SV Angel, @balajis, and many more incredible folks who have taken a chance on us; it's been my mission for the last 3+ years to make sure that everyone involved in this venture does phenomenally well.

Versatile back end code and infrastructure development services. Typical deliverables are Dockerized microservices specified by OpenAPI, written in Go or Python, with a REST/JSON API and backed by PostgresDB or MySQL. And of course your custom business logic.
I take your OpenAPI spec and implement it, or I can help you develop your back end infrastructure from the ground up. Basically I offer back-end componenets you can slot into your Kubernetes or Docker environment from day one.
On the business side, you get a fractional developer for a no-haggling fixed monthly rate, corp-to-corp billing, long term support for your code, careful vetting of dependencies for licensing and security, and a professional approach to your technical needs.

I’m a generalist engineer with past experience including full-stack engineering at a YC legal-tech startup and full-stack + cloud infra at an NYC quant fund. I also have entrepreneurship experience that gives me an understanding of the end-to-end product development process at early stage startups.
My recent projects include building a realtime voice-based AI personal assistant—one that actively calls you on the phone, rather than passively waiting for you to interact with it, as well as a philanthropic project in the AI ed-tech space.
I’m skilled at taking initiative on projects and synthesizing requirements from multiple stakeholders into meaningful technical solutions. I’m passionate about functional programming, building reliable and scalable distributed systems, and optimizing developer experience. I also speak 4 languages (English, Sinhala, Mandarin Chinese, and Thai).

Very competitive pricing available for fast turnaround PHP / JS or Node projects. If you are looking to develop a new project, clean up/refactor an existing one or something else/different then please get in touch. Just as happy to work on legacy/vanilla PHP applications as Laravel apps, or to port from one to the other (or give opinions on feasibility of that for your project).
I like to work in a methodical way, typically writing simple tests for new functionality as I go, and also isolating any bugs/likely bug surface area. At the same time I also get satisfaction from "shipping". So it's important to me to achieve a harmonious balance between these, so expect this to be an area of focus in terms of communication. My technical interests are anything from simple CRUD/REST APIs through to integration of more advanced features, which could be real time application (Pusher/Websocket, possibly Reverb when this is released) or integration with ML models and pipelines.
