Notes on software, architecture, and the details that make systems work. Written from experience, shared for the next build.
GitFlow, GitHub Flow, GitLab Flow, and trunk-based development — what each is, when each fits, concrete branch diagrams, the release ceremonies they imply, and how to actually pick one in 2026.
Read articleHow to build deploy workflows that are fast, safe, and survive the 3 a.m. incident — secrets, environments, OIDC, caching, rollback, SSH vs runner-based, and the anti-patterns that catch every team once.
The thirty-something git commands you actually use day-to-day — staging, branching, merging, rebasing, recovering from mistakes, and the small set of aliases worth setting up once.
Stop reading about DevTools and start using it. Save one HTML file, open it in Chrome, and run twelve guided experiments — conditional breakpoints, DOM watchers, network replay, paint flashing, performance recording, and the shortcut moves that fix real bugs in real time.
Real project-management situations — scope creep, budget cuts, people leaving, vendors failing, deadlines shifting, compliance landing — each with step-by-step moves, the exact documents that must change, and best/worst case outcomes.
A ground-up, technical introduction to blockchains — hashes, blocks, Merkle trees, proof-of-work, consensus — paired with a ~200-line TypeScript toy chain you can run, fork, and break. The version of the explanation that assumes you're a developer, not an investor.
A structural, symbol-by-symbol guide to flowcharts — ANSI/ISO 5807 shapes with real meanings, when each one applies, how to lay out process, swim-lane, and data-flow diagrams, and ready-to-copy Mermaid examples.
A ground-up introduction to Apache Kafka — what it actually is, the handful of features that matter, the use cases it's genuinely good at, and working producer/consumer snippets in four languages so you can run your first topic in under ten minutes.
A practitioner's walk through PMBOK — the five process groups, the ten knowledge areas, and, for each part, the inputs that feed it and the artifacts that come out. The bits you actually keep on a shelf.
A ground-up introduction to Redis — what it actually is, the handful of data structures that matter, the use cases it's genuinely good at, and working client snippets in four languages so you can run your first cache, queue, and pub/sub in under ten minutes.
A structural, named-technique-by-named-technique walkthrough of the attacks a modern web application has to defend against — injection, authentication flaws, XSS, CSRF, IDOR, SSRF, deserialization, race conditions, supply-chain attacks, and more — with how each works and what to do about it.
