Portrait of Andrei Calugar

Hi, I'm Andrei. I build production software, fast, efficient and mostly solo.

Full-stack engineer working across React, TypeScript, Next.js, Node and Python, with AI-accelerated development. I take products from empty repo to live in production.

Currently building my own products. Previously frontend at Saxo Bank. MSc from DTU Copenhagen.

Selected work

A few things I've designed, built, and shipped. Usually end to end, usually solo.

  • Sole architect and developer of a full production system for a European velomobile manufacturer: order configurator, production scheduling, and a shop-floor app. Taken live in roughly 10 weeks.

    Private client project, so the system itself isn't public. Case study coming soon.

    • Next.js
    • TypeScript
    • Supabase / Postgres
    • plpgsql
    • Vercel
  • An AI tool that reads a creator's competitors' best-performing Instagram content and returns ready-to-film content briefs. Not another dashboard, an actual decision on what to make next.

    • Next.js
    • Claude API
    • n8n
    • Apify
    • Supabase
  • Paste a job ad and get a calibrated match score, the requirements you miss with a plan for each, and a pre-mortem in the hiring manager's voice. Every claim in the generated application kit is checked against your CV, so nothing is invented.

    Free and open source. Built in public, with versioned prompts and a published eval harness.

    • Next.js
    • TypeScript
    • Supabase
    • LLM evals
    • Vercel

About

I'm a full-stack engineer with six years across the stack. Three of them at Saxo Bank on trading-platform frontend, plus backend work in C#/.NET at SimCorp, and an MSc from DTU Copenhagen. These days I work mostly for myself: building my own products, taking on select client projects, and shipping whole systems solo by leaning hard on AI-accelerated development.

I care about the same things in every project: real problems, whole systems, actually shipped. When I'm not at the keyboard I'm usually on a bike somewhere, or climbing walls. I love watching Formula 1, and recently discovered storytelling through video as a way to express myself creatively.

Questions

Are you open to full-time roles?

Yes. Remote, or hybrid around Copenhagen. I'm selective rather than closed: the work has to be something I'd choose to build. Frontend-heavy or full-stack both work.

Do you take freelance and contract work?

Yes, and it's most of what I do right now. I take a small number of projects at a time so each one gets shipped properly rather than parked.

What does 'built solo' actually mean?

Architecture, database, backend, frontend, deployment, with no team to hand pieces to. AI-accelerated development is what makes the timelines possible; the judgement about what to build is still mine.

How fast can you start?

Usually within a week or two. Book a call and I'll tell you honestly whether I'm the right fit before we talk scope.

Let's build something

Open to Copenhagen-based roles, remote, freelance and contract work, and interesting collaborations. If you've got a problem worth solving, let's talk.

I write about building products in public: the wins, the mess, and what I learn using AI to ship faster. No spam, just the journey.
