What I'm looking for

I'm looking to build scalable backend systems and real-world products where I can work on APIs, databases, automation, and data-driven engineering challenges.

I've built production-grade backend systems at Brick and Bolt, including an OCR ingestion pipeline for scanned receipts and invoices and an LLM-powered expense classification workflow that achieved approximately 92% accuracy.

My projects include a real-time pothole detection system that reached 93% classification accuracy across 2,000+ images, with FastAPI services for geolocation ingestion, deduplication, and reporting. I also built DriveKaro, a booking platform with concurrent reservation handling and Stripe payment workflows, reducing database response latency by 35% under simulated load.

I enjoy designing secure, efficient APIs and optimizing data systems with Node.js, Python, SQL, MongoDB, and PostgreSQL. I've solved 250+ competitive programming problems and contributed to 8+ full-stack GitHub projects.

Software Developer Intern

The Brick and Bolt

Jan 2025 - Jul 2025 (6 months)

Developed an OCR-driven ingestion pipeline to digitize scanned receipts and invoices, extracting structured line-item data and reducing manual entry effort for internal finance operations. Applied an LLM to interpret extracted fields and auto-classify expenses into spending categories, achieving ~92% accuracy and streamlining downstream financial reporting.
