Projects

What I've built

Live links and repos where they exist. Each name goes to the full case study — problem, approach, outcome.

  • Pastrac

    React Native · Supabase · iOS

    An iOS app for pinning the places that matter to you — drop a pin on a live map, attach notes and photos, categorise the moment, then choose who sees it.

    pastrac.com ↗ App Store ↗Case study →

  • Collaborators

    Next.js · Solana · Prisma · NextAuth

    Turns verified GitHub activity into on-chain rewards. Maintainers set bounties on open issues; contributors get paid to their wallet once the work is reviewed.

  • Med Prep

    Ruby on Rails · Stripe · PostgreSQL

    The testing and e-learning platform behind a Swiss medical-school prep school — thousands of practice questions, timed mock exams, scoring and subscriptions.

  • Crypto Staking Calculator

    React 18 · Material UI

    A retro arcade–styled staking calculator that estimates rewards and compares plain APR against compounding. A finance tool with a personality, shipped end to end.

  • Archeo

    Ruby on Rails · TailwindCSS · PostgreSQL

    An internal platform for an excavation company running on dozens of Excel sheets where nobody was sure which file was current. Sites, crews and hours in one system.

  • R&T product platform

    Django · React · Python

    Built with a large team for a multinational personal-care manufacturer: tracking every product through research and testing before it reaches market.

    Case study →

  • Agency automation

    TypeScript · Puppeteer · Firebase · Stripe

    Puppeteer tooling that took the repetitive browser work off a marketing agency's virtual assistants — plus leading and mentoring the team that maintained it.

    Case study →

  • DSS Inox

    JavaScript · Firebase Hosting

    A service site for a stainless-steel fabrication business in Mediaș — the kind of small-business web presence that has to load fast and be trivial to update.

    Live site ↗ Code ↗Case study →

  • WallApp

    Android · Java

    A wallpaper app built to promote Romanian artists rather than bury them in a feed — set wallpapers, follow creators, save favourites. Shipped to Google Play.
