Services

Available for freelance work.

Product builds, performance reviews and appsec passes — scoped, measured, shipped.

Full-stack product build
A working first version, end to end — schema, API, UI, deploys — built the way KICKBUZZ was: shipped, not prototyped.
Next.js & performance review
A read of an existing app: rendering strategy, bundle, data fetching, Core Web Vitals — with the specific changes that move the numbers.
Secure-by-default review
An appsec pass over auth, access control, input handling and secrets — informed by hardening KICKBUZZ after a real credential-stuffing attempt.
