I'm Alinus Dumitrana

Based in Romania

Available now for long-term roles

11+ years of experience across AI, fintech, energy, and crypto. I enjoy working on complex systems and helping teams ship reliable software.

Solving Complex Software Integration Challenges

The Problem

As systems grow, things get messy. Services stop talking to each other cleanly, migrations stall because nobody wants to own the risk, and the codebase becomes something people work around rather than with. These are the kinds of problems I find interesting.

How I Help

I've helped migrate legacy platforms to modern stacks, worked on PCI-compliant payment systems, and contributed to AI-powered products on tight timelines. I'm most useful when there's a complex technical problem that needs someone who can work across the full stack and keep things moving forward.

Look at my journey

Jun 2026 – Aug 2026

Evantis Technology

Senior Software Engineer

A three-month backend engagement on an AI voice product for a UK home-services marketplace — unfamiliar in-house tooling, ambiguous AI-generated data, and every piece of work documented as it landed.

Aug 2025 – Mar 2026

SysWeb Company

Software Engineer

Owned the frontend for a government internal management platform — built it from scratch with React and TypeScript, working directly with the design and backend teams.

May 2025 – Feb 2026

YLD

Software Engineer

Returned to YLD to work on a UK fintech client — migrated pages from Angular to Next.js in a multi-brand, multi-tenant architecture, and contributed to a Node.js GraphQL BFF.
