Selected systems 01 — 03
Each project starts with the same question: what makes this dependable under real use?
Identity infrastructure · Go
A self-hosted auth microservice that combines a Go/Gin gateway with Keycloak—designed around local JWT verification, JWKS caching, refresh rotation, RBAC, and rate limits.
Commerce engine · Node.js
A complete commerce API covering authentication, catalogue discovery, carts, vendor authorization, and Stripe payments—shaped around clear REST contracts and secure user flows.
Lean web service · Go
A lightweight snippet-sharing platform built with Go’s standard library. Server-rendered templates, pgx connection pooling, and deliberate simplicity keep the system crisp.
Engineering approach Designed for the long run
Thoughtful API contracts, dependable error paths, and clean architecture that let teams move without breaking each other.
