I've shipped production Python and TypeScript systems where correctness matters, from payroll automation to offline-first court software. My strongest tools are Python, FastAPI, PostgreSQL, Docker, and Kubernetes.

At M. Abubakar Construction and Engineering, I replaced a shared spreadsheet workflow with a normalized PostgreSQL tracking system, reducing document and certificate reconciliation from three days to under four hours. I also built a PyQt6 payroll application that eliminated more than 15 hours of weekly manual data entry across a 50-employee payroll cycle.

As a freelance engineer, I delivered an on-device wood knot detection pipeline for AdZU researchers, training YOLOv8 on 12,000 images and shipping ONNX-to-TFLite inference. At the Regional Trial Court, Region 9, I built offline-first software and bidirectional synchronization that reconciled 1,000+ records after outages with zero data loss.

I'm especially interested in secure backend systems, distributed synchronization, and practical automation. My projects include a payroll platform with AES-256 encryption, JWT authentication, bcrypt hashing, RBAC, and audit trails, plus a Kubernetes-deployed conflict-resolution API using vector clocks and JSON Patch.
