Haynes Lab is a senior full-stack engineering studio for founders and early-stage teams. We turn MVPs into real, production-grade products without the usual chaos, rewrites, or blown budgets. You work with the engineer directly, not an agency padding estimates with overhead. Over a decade building and scaling high-traffic systems, including one platform taken from zero to $200k+ MRR in under a year, plus founding a software company in 2013 and selling it in 2024. What we build: - MVP to production SaaS - Scalable backends in Node.js, TypeScript, and MongoDB - Full-stack web apps with React and Next.js - Payments and subscriptions with Stripe - Infrastructure, CI/CD, and automation on AWS - Real-time systems, background jobs, and internal tooling - Embedded firmware and IoT on STM32 and ESP32 - ML features and AI integrations with OpenAI and custom models On-site hardware lab, so we prototype, test, and build physical products in-house: - 2 Bambu Lab 3D printers for enclosure and part prototyping - Rigol DHO924S oscilloscope (250 MHz, 12-bit) for embedded and power debugging - Miller Multimatic 215 welder (MIG/TIG/stick) for fabrication and mounting - Raspberry Pi fleet for edge testing and provisioning - 2 AMD Threadripper PRO 7995WX servers (96-core) for builds, CI, and staging - 2 NVIDIA RTX 4090 GPUs plus Jetson for training, inference, and edge AI - Rigol DP832 bench supply, Hakko rework station, USB protocol/power analyzer, laser engraver Senior decisions, clean code, fast delivery, and no long-term technical debt.
