whiterage/README.md
whiterage — Go backend engineer

I write backend services in Go and came up through C and C++, so I tend to know what the abstraction is standing on. Most of what I build is REST APIs, background workers and command-line tools — plus a stubborn interest in implementing algorithms and data structures from scratch.

Selected work

Backend services

Project What it is
task-tracker Task management API with JWT access/refresh auth, rate limiting, metrics and swappable storage backends
opa-auth-service Authorization delegated to Open Policy Agent — Keycloak-style JWT claims evaluated against embedded Rego policies
geo-alert-core Geo-alerting backend on Clean Architecture — Gin, PostgreSQL, Redis, webhook integration
link-checker-service Async link checker built on a worker pool and job queue, with PDF reporting. Standard library only
subscriptions-api Subscription aggregation service — cost roll-ups over date ranges, SQL migrations, OpenAPI docs

Algorithms and systems

Project What it is
simpleNavigatorGolang Graph algorithms written from scratch — Dijkstra, Floyd–Warshall, Prim, and three travelling-salesman solvers
MazeGo Maze generation and pathfinding — BFS and Q-learning solvers, cellular-automata caves, desktop and web frontends
3DVIEWER Wireframe 3D model viewer in C++20 and Qt — STL and OBJ parsing, affine transforms, GIF recording
CPP_STL_Containers STL containers reimplemented in C++20 on RAII, templates and move semantics

Stack

Area Tools
Languages Go, C, C++20
Storage PostgreSQL, Redis, SQLite
Tooling Docker, Linux, Make, Git
Testing go test, GoogleTest
Learning now Distributed systems, observability, Kubernetes

How I work

explicit APIs over clever abstractions
small boundaries over tangled ones
measure the hot path before tuning it
