About Alex

Full-stack developer with 5+ years of experience building production web applications and SaaS products. I specialize in React, TypeScript, Node.js/NestJS, and modern backend stacks — with a strong track record delivering end-to-end features across fast-moving startups.

I'm the founder of FluentAI, a language-learning Chrome Extension for Netflix and YouTube that grew to 100 paying customers. I've worked as a Technical Lead at Sciense (Next.js 15, Supabase, tRPC), as a freelance developer at Kolleno (React, NestJS, Redis), and as a full-stack developer at Embie (Next.js, GraphQL, Playwright).

Currently also building Acepe.dev, a desktop app for unified AI agent interactions using Tauri + SvelteKit + Rust.

What I bring to your project:
- Full-stack ownership: from database schema to polished UI
- Clean, tested code with TDD and Playwright E2E
- Fast autonomy in new codebases (Odoo legacy, startup greenfields)
- Product mindset — I've shipped products used by real paying customers

Looking for freelance missions in web development, SaaS, or AI-adjacent products. Remote-first, available immediately.
