Production systems, shipped & measured.
Every project below runs in production. Problem → solution → measurable outcome, with the architecture decisions that mattered.
AI Invoice Generator & Management
Problem — finance teams losing 12+ hrs/week to manual invoice processing; off-the-shelf OCR below 60% accuracy.
Solution — hybrid pipeline: GPT-4 Vision extraction → Tesseract fallback → deterministic validation. SQS + Lambda for burst handling.
ServerlessFlow — AWS Lambda alternative
Problem — vendor lock-in and opaque pricing in commercial serverless; teams needed self-hosted, predictable-cost FaaS.
Solution — OpenWhisk orchestrator + container pool with pre-warming; scheduler prioritizes reuse over creation; cgroup-isolated execution.
Everything else lives on GitHub
CLI tools, infrastructure scripts, OSS contributions, and experiments in Rust & edge compute. The archive tells the fuller story.
