I build backend systems that stay fast when the load doesn't stay small.
Software Engineer at Multi Commodity Exchange. I design distributed data pipelines, streaming systems, and production GenAI applications.
How I work
I turn fragile monoliths into resilient, observable pipelines. Most of my work sits where throughput, correctness and compliance meet: financial data that has to be right, fast, and auditable.
-
Design for the failure mode
Traffic spikes, partial outages and bad input will happen. Guardrails and observability ship with the first version, not after the first incident.
-
Measure, then optimise
Query plans, latency percentiles and profiler output decide the redesign. The 92.5% and 50% wins came from data, not guesses.
-
Ship systems people can trust
From JWT-gated gateways to LLM guardrails in a regulated environment, reliability and safety are requirements, not features.

Where I've been
Software Engineer
Multi Commodity Exchange · Mumbai
Jun 2025 — Present
Production REST APIs and distributed data pipelines for client lifecycle management on India's largest commodity exchange.
Key achievements
- File validation time
- 92.5%faster · 40 min → 3 min
- API search latency
- 50%lower via indexing & query redesign
- RAG pipeline latency
- 40%lower with 5-way parallel retrieval
- Users on shipped APIs
- 100M+on India's largest commodity exchange
What I worked on
- Re-architected a legacy monolith into a distributed Python / Celery / Redis pipeline, cutting file validation from 40 to 3 minutes.
- Built a real-time Kafka ETL pipeline and anomaly-detection engine that raises multi-channel alerts on suspicious trading behaviour.
- Halved API search latency through query optimisation, schema redesign, B-Tree indexing and SQLAlchemy refactoring.
- Designed a custom Nginx API gateway with JWT authentication and rate limiting to shield downstream services from traffic spikes.
- Provisioned and hardened UAT and pre-prod environments: Redis, Nginx reverse proxies, end-to-end logging and observability.
- Built internal automation tools adopted company-wide, removing manual operational workflows.
