Isolated Spinny's payments database from the monolith to handle INR 1B+ monthly transaction volume independently. Built custom Django DATABASE_ROUTERS for read replica load balancing and extended GraphQL to support replica-aware queries. During this work, discovered a bug in Django's RelatedManager.add() when objects cross database boundaries — wrote and submitted a patch for Django ticket #35974.
Selected work across corporate infrastructure, open source, and independent projects.
7-state Finite State Machine unifying multiple aggregator and banking integrations with atomic DB transitions and Kafka async refund retry.
Declarative field-level auditing via Django signals. Zero audit code in views — both .save() and bulk .update() covered.
AI-powered test generation CLI for legacy Python codebases. Uses AST parsing for code structure extraction, runtime parsing with git history for context retrieval, and a LangGraph agent with Claude for test generation. Supports PR diff-test mode for CI integration. Published on PyPI.
Framework-agnostic Python state machine with atomic transitions, @pre/@post/@validator hooks, and pluggable ORM adapters. Built for production payment flows at Spinny, now powers their payment gateway processing INR 1B+ monthly. Open source version separately Published on PyPI.
Spinny is India's largest platform for buying and selling pre-owned cars. I work on the Payments team, building the infrastructure that processes all online transactions — payment gateway integrations, refund automation, database isolation, and internal tooling. The system handles INR 1B+ in monthly transaction volume.

Recent learning: Go, vector databases, and the Django specialization that preceded production work.
Backend engineer at Spinny, where I build and maintain the payments infrastructure processing INR 1B+ monthly. My work spans payment gateway design, database architecture (read/write replica routing, microservice isolation), and distributed systems (Kafka, Celery, async processing).
I'm an open source enthusiast — I identified a bug in RelatedManager.add() during production scaling at Spinny and submitted a patch for ticket #35974. I also maintain two open-source Python packages on PyPI: a state machine framework used in production at Spinny, and CodeContext, an AI-powered test and documentation generation command line tool.
I'm currently exploring opportunities with multinational technology companies, particularly in Japan and the Asia-Pacific region. This is a personal choice driven by cultural and artistic motivation. I'm drawn to teams building products at scale where backend engineering depth matters.
