I'm Adrien, senior developer and CTO with 10+ years of shipping software. Through Ellin Tech I work with companies as a technical advisor — architecture reviews, code audits, hiring support, honest feedback. Async, remote, based in Belgium.
I work with companies that are building or maintaining software without someone senior enough to make the hard technical calls.
I join your Slack or Teams, review architecture decisions, help you hire devs, and tell you when you're overengineering something. Think of it as having a CTO on call without the salary.
I read your code, your infra setup, your deployment pipeline. You get a short written report: what's solid, what's going to hurt you in 6 months, and what to fix first. Typically done in two days.
If you need something built — a prototype, an internal tool, a customer-facing app — I can do that too. We define the scope together, I ship it, you own the code.
I'll tell you what's good, what's going to cause problems, and what to do about it. If I'm not the right person for your problem, I'll tell you that too.
I'm not just giving opinions from the sideline. I read your code, review your PRs, and can build things myself when needed.
I work remotely, on my own schedule, without disrupting yours. Slack, Teams, email — whatever works for you.
Send me an email. Tell me what you're building and where you're stuck. I'll get back to you within a day or two.
I send you a short proposal: what I'll do, how long it takes, what it costs. Clear and simple.
I join your communication tools and start delivering. Reviews, audits, hiring help, or builds — whatever we agreed on.
Monthly advisory continues as long as it's useful. One-off projects end with a deliverable you own.
I'm currently CTO at an early-stage startup, building the product and team from scratch. Before that I spent years as a senior developer in consulting, where I was part of growing a dev studio from 4 to 15 engineers — I saw firsthand what works and what doesn't when scaling a technical team.
I've shipped software with React Native, TypeScript, PostgreSQL, and plenty of other things, but the stack matters less than knowing when to keep things simple and when complexity is actually justified. Most of the expensive technical mistakes I see come from building too much, too early.
I take on a few advisory clients alongside my own work. I'm not scaling a consulting business — I like the variety and the problems. If my plate is full, I'll tell you.
English and French. Based in Belgium, work remotely.
I'm a senior developer who also thinks about the bigger picture — architecture, team structure, tech choices, priorities. Think of it as having a CTO-level opinion without hiring a full-time CTO.
It depends on what you need. Send me an email describing your situation — I'll come back with a clear proposal. No surprises.
For monthly advisory, expect async reviews and availability on Slack or Teams for quick questions. We'll agree on the right level during our first exchange.
No. I work with any company building software — startups, SMEs, agencies, solo founders. The common thread is needing senior technical guidance without hiring full-time.
Both. I can review your architecture and also build prototypes, internal tools, or apps. We define the scope together, I ship it, you own the code.
Yes, fluent in French and English. Based in Belgium.
Drop me an email. Tell me what you're building and where you're stuck.
