I build backend systems at the intersection of scale, correctness, and clarity, and write about the parts that are usually hand-waved away.
A decade-plus of building things that have to keep working when nobody is watching: payments infrastructure handling billions of transactions a month, compliance-grade communication and archival platforms, and now cloud-connectivity primitives. The repositories below are the residue of that habit - code I wrote to understand something at depth, not to ship a feature.

A laboratory for the unhappy path. Production-quality Raft consensus in Go — built not just to work, but to fail in reproducible ways that mirror real production incidents. Leader election, log replication, fast log backtracking, partition recovery, durability under fire.

A distributed KV store with the hard parts on display. Tunable consistency, MVCC, replication-lag measurement, and the phantom-durability trap reproduced and documented. The internals are the product.

Retrieval-augmented generation, from first principles. An end-to-end RAG platform: ingestion, hybrid retrieval, re-ranking, generation, caching, evaluation. Companion to an eight-part series on the trade-offs behind each layer.

Karpathy's micro-GPT, ported to the JVM. A from-scratch GPT implementation in Java — tokenizer, attention, training loop — written to demystify what every

Clock primitives for distributed systems. Logical, hybrid-logical, and vector clocks; bounded-skew time — implemented as a single, production-grade Go library so causality becomes a dependency, not folklore.

A decade of long-form, code-first writing. The codebase that powered years of public technical writing — algorithms, Java internals, Spring, AEM, distributed systems. Read by engineers in 100+ countries.
