I'm Jarn — a Lead Software Engineer focused on building scalable, well-designed products across web and mobile.
I work at the intersection of engineering, UX, and execution — turning ideas into production-ready systems that are fast, maintainable, and actually useful.
- Backend: PHP, Symfony, API Platform, MySQL
- Frontend: React, React Native, Expo
- Infra: Docker, AWS (RDS, S3, SQS, CloudFront)
- Tools: GitHub, Postman, PhpStorm
- Build full-stack applications from idea → production
- Design clean, scalable backend architectures
- Develop performant web and mobile frontends
- Ship fast while keeping systems maintainable
- Clarity over complexity
- Build for real users, not demos
- Speed matters — but not at the cost of quality
- Good UX is part of engineering
- Product engineering (not just feature building)
- Mobile apps with React Native / Expo
- Developer tools & internal systems
- Shipping products end-to-end
- Cycling
I build with intention — not just features, but products people actually use.
- Ceremo — wedding RSVP platform (Next.js, Prisma, AWS)
- Ekko — anonymous geo-based micro-posting platform
- Inspek — bug reporting & session diagnostics tool
