I design and ship product-grade web apps — from polished interfaces to the APIs that power them.

About

Frontend-oriented full-stack developer with 3 years of commercial experience.

I work full-time as a Consultant at Awumba, building nearshore software for clients across React, Next.js, and .NET. Outside of that role I build my own products — SpendBeacon and Lekcjo — and occasionally take on small personal commissions in the evenings and on weekends: marketing pages, landing sites, and compact web systems. My day job always comes first.

Outside my full-time role I’m selectively open to personal commissions — marketing pages, landings, small systems, and scoped MVPs. Work happens in my free time only; capacity is limited and timelines stay honest.

  • Marketing & landing pages
  • Small web systems
  • MVP / prototype builds
