Bridging business specs with engineering rigor.

Built an ESP32-based hardware telemetry system that streams particulate and atmospheric data to Arduino IoT Cloud over Wi-Fi via MQTT with 10-second polling. Engineered fault-tolerant reconnect and exponential backoff logic for edge Wi-Fi drops, reducing manual monitoring effort by 95%.

Shipped a lightweight multithreaded Python system-tray utility that calibrates display luminance using camera feed on Windows laptops lacking hardware ambient light sensors. Utilized OpenCV for real-time luminance estimation, reducing manual adjustments by ~90%.

End-to-end Retrieval-Augmented Generation pipeline enabling conversational querying across unstructured PDF documentation. Implemented FAISS vector search achieving 1–5ms retrieval latency, token-optimized chunking, and strict context-constrained prompting.

SaaS application converting raw meeting transcripts into structured action items with assigned owners, priority scores, and deadlines via JSON-structured schema prompting. Built with isolated tenant auth via JWT, FastAPI, and SQLAlchemy.

High-performance spaced repetition scheduler in modern C++ implementing the SM-2 algorithm. Guaranteed zero-plaintext local persistence using AES-256 encryption, Argon2 password hashing, and authenticated ciphertext verification.
