From idea to working system
Product Development & Web Apps
I build digital products and web apps for teams that don't just want something launched, but something that keeps working — maintainable, scalable and supported by real users.
Many digital products start strong and end up as legacy. Not due to bad code, but due to missing system choices: roles, data, processes, ownership.
A product that starts small, delivers value fast, and grows without rebuilding.
For whom
- Founders who need a first serious product version
- Product teams that need to connect discovery and delivery
- Organisations with internal tools ready for a real application
What I deliver
- Product discovery and scope prioritisation
- Architecture on Next.js, Supabase, FastAPI and modern deploy flows
- MVP in production — with measurement points and iteration path
- Handover or longer-term product development partner role
What a trajectory looks like
Discovery
What are we solving? For whom? What is truly version 1?
Build
Iterative, in production-like environment, from week 1.
Iterate
Measure, learn, prioritise — don't build on gut feeling.
Frequently asked questions
- What stack do you use?
- Standard: Next.js, TypeScript, Supabase (Postgres + Auth + RLS), FastAPI for heavier jobs, Vercel + Railway for deploys. Adaptable when context demands it.
- Do you work solo or with a team?
- Both. For MVPs often solo; for larger trajectories I bring specialists — design, embedded, data — who work in the same style.
