I built Jiraya, a FastAPI service that automates Gmail replies, calendar events, and GitHub issues, with workflow definitions and execution history stored in PostgreSQL. I scoped workflows to user accounts and added approval gates, duplicate-write guards, and provider-record verification.
Jiraya passed 106 unit, API, and regression tests using simulated model and provider responses. The tests covered account isolation, expired sessions, execution failures, and replay handling.
I released a habit, task, and journal app used by 50+ developers, connecting a Flutter client to Spring Boot REST APIs and PostgreSQL. I implemented backend services across controller, service, and repository layers, along with Gemini journal processing and media uploads.
I also built BatchRunner, a Node.js API for configurable, voice-guided manufacturing batches using AssemblyAI. As a Programmer with the Robotics Committee, SFIT, I programmed STM32/ESP32 firmware for locomotion and picking with the Robocon team.
