Full-stack TypeScript developer working in a niche most developers avoid: automotive ECU firmware and proprietary binary formats — plus the production APIs and apps around them.
Deep specialization in binary work, wrapped in the full stack needed to ship it as a real product — not a prototype.
Hex-level structure mapping, checksum handling, and reverse engineering of proprietary or undocumented file formats.
Node.js / TypeScript on Fastify, Knex & Prisma, MySQL / PostgreSQL, Redis — validated inputs, rate limiting, tested.
Next.js and React, internationalized (9 languages in production), Tailwind — polished, responsive interfaces.
Electron applications that talk to real hardware, including USB dongle integration and native bridges.
HMAC request signing, replay protection, per-user quota systems, and standardized error handling on every route.
Given only sample files, I map the layout — offsets, records, encodings, checksums — and turn it into typed code.
The production SaaS I designed and run for the automotive chiptuning industry — every stage built, secured, and shipped by me.
2–8 MB ECU firmware in via web UI or HMAC-signed B2B API.
Signature scan identifies ECU family and software version.
Hex-level location of diagnostic trouble code tables.
Changes applied in place; checksums recalculated.
Flash-ready file returned, with per-user audit trail.
Binary parsers, APIs, or a full-stack build. Send me a few sample files and what you need out of them — I'll confirm feasibility before you commit.
