Senior developer, end to end
Hi, I'm Alex Voina. I've been building and maintaining business-critical web and mobile applications for 15 years. I work end to end: database design, APIs, frontend, mobile apps, deployment and server management. I'm comfortable as the solo developer who owns a product, or as a senior member of an existing team.
I lived in the Netherlands for 34 years and now work from Sibiu, Romania (one hour ahead of Central Europe). I speak Dutch and English fluently, and my hours overlap comfortably with both Europe and the US East Coast. I invoice through my own EU company, Sigma Information Technology SRL.
What I'm known for
- Multi-tenant SaaS in Laravel and Vue, with a separate database per customer, billing, 2FA and role-based access.
- Legacy systems nobody else wants to touch. I take over undocumented PHP and CakePHP applications, document them, write tests and modernise them while they stay in production.
- AI that doesn't put your business at risk. Drafts and research reports that a person approves, cited sources, and AI access limited to the data it needs.
- Payments that hold up under retries, duplicate webhooks and race conditions.
How I build
I design the architecture and conventions myself. Most of my career was long before AI coding tools existed, so I know what good code looks like and why. Today I use Claude Code as a fast pair of hands, under rules I wrote: project instructions, static analysis (Larastan), linters and CI that blocks anything that doesn't pass. I review and correct every change. You get senior judgement at a faster pace, and code your next developer can still understand.
How I work
I communicate clearly, write documentation, commit in small reviewable steps and treat production as sacred. Before a big change I make sure we can prove nothing broke: tests first, then old and new compared on real data. What I find along the way, I fix and report, also when nobody asked. After a major update I keep watching the logs, so problems are fixed before you know there was one. And when something threatens your system, I call you before it becomes your problem.
Questions I get asked
Do you work alone?
Yes. You deal with one person, and that person does the work. If a job needs more hands than mine, I say so before we start. I stick to standard frameworks and write tests and documentation, so another developer can always pick up where I left off.
You are in Romania. How does that work for a Dutch or American company?
I lived in the Netherlands for 34 years and speak Dutch fluently. I am one hour ahead of Central Europe and reachable during Dutch office hours; with the US East Coast I share the afternoon. You get a contract and an invoice from my EU company, and for a kick-off or workshop I can come to the Netherlands.
Do you use AI to write code?
Yes, as a fast pair of hands, under rules I wrote myself: project instructions, static analysis, linters and a CI pipeline that blocks anything that does not pass. I review and correct every change. Most of my 15 years were before these tools existed, so I know what the code should look like.
What does it cost?
The code review is a fixed €950. A project with a clear scope gets one fixed price in a written quote, with milestones. Open-ended work, such as maintenance or joining your team, is billed per hour. You always know the price before I start.
Can you take over a system that someone else built?
That is a large part of my work. I first read the code and write down how it works, then cover it with tests, and only then change it. Systems without documentation, on old PHP versions, with the original developer gone: that is the normal case, not the exception.
Do you also host and maintain it afterwards?
If you want that, yes. I manage my own servers at a Dutch hosting provider, with deployment, backups and monitoring. For sensitive data I set up a separate environment. You can also keep it with your own hosting party; then I deliver to that.
Let's talk about what you're building
Tell me what you need, and I'll tell you honestly how I would approach it, how long it takes and what it costs.
