Work
Products and systems in production, plus a lab of experiments. Every card links to something you can open and check for yourself — a store listing, a live deployment or the source code.
Magazine app: content reader with infinite scroll, clock-synced linear stream, offline reading, push notifications (FCM v1 + APNs) and trilingual PT/EN/ES on a custom WordPress REST backend. Taken end to end, including Apple and Google review.
Audio-visual QC in the browser, deployed in an EdTech pipeline that delivers thousands of hours of content per month: real-time RGB Parade, Waveform and Vectorscope on Canvas, byte-range streaming proxy, optimistic locking for multi-analyst queues, 129 tests in CI.
Case study →Contest platform for a magazine: landing page, lead capture with dedupe and scoring, transactional email and deploy pipeline.
source ↗WordPress plugin suite that drives the magazine app: custom post types, REST endpoints, push notifications, advertising and PT/EN/ES translation.
source ↗Media ingest as a service: yt-dlp + ffmpeg engine, FastAPI API, Celery workers, progress over SSE, signed delivery links, quotas and abuse controls.
source ↗Serverless Telegram bots on Cloudflare Workers with a shared TypeScript core — transcription, media tooling and credit handling.
source ↗Small offline-first tools, each one wrapping a real engine written in another language (OCaml, Prolog, COBOL, Fortran, Zig, Lua, Nim…) and compiled to WASM or JS. These are learning experiments, not products — the repositories report JavaScript because that is the compiled output.
All repositories on GitHub →Contracts and full-time roles. Fast replies, working software, no drama.
