I build the tools and references I wish already existed — then publish them, in case the problem was yours too.
Scalable backend systems, language internals, and software architecture — turned into things you can actually use: an OpenAPI generator for Go, visual references for engineers, and a handful of small, sharp services.
Most of what I publish started as something I needed. The bet is simple: if a problem cost me a weekend, it probably cost you one too — so the solution belongs in the open, with the reasoning intact.
Every project answers a question I actually hit in production or while learning — not a hypothetical one.
Apache- and MIT-licensed Go, tested and documented, so anyone can read it, run it, or take it further.
The reasoning matters as much as the code. References, diagrams and docs make the “why” reusable too.
A few open-source projects worth your time. The full list — experiments and all — lives on GitHub.
OpenAPI 3.1, generated from real Go code
Point it at a Go module and get an accurate OpenAPI spec — routes, parameters, request and response bodies — inferred by walking the call graph, not from annotations that drift. Detects Gin, Echo, Chi, Fiber, Gorilla Mux and net/http. Ships a CLI, a browser UI, and an interactive call-graph explorer.
A visual guide to software architecture
Foundations, architectural styles, DDD, microservices, event-driven and distributed systems, APIs, cloud & SaaS, and the architect’s path — with diagrams, trade-offs, quizzes, progress tracking and Arabic localisation.
A Go-first reference for Go engineers
The whole stack from the language itself to internals, systems and architecture — with diagrams, runnable Go, quizzes and progress tracking.
A workflow engine on Petri-net foundations
Orchestrate steps, tasks and data in Go with reliable flow management and visualization. Built on Petri nets, inspired by the Symfony Workflow component, with a focus on portability.
A small, self-contained user-management service
A Go user-management system backed by BoltDB — a compact reference for auth and storage without dragging in a database server.
Account-to-account transfers, simulated
A small API that simulates money transfers between accounts — a clean walk-through of modelling balances and moving money safely.
