What I'm looking for

I’m looking for a role where I can build reliable, scalable backend services and event-driven pipelines—owning REST APIs, databases, and orchestration. I want to work on systems that process real-time data at scale while keeping code maintainable.

I’m a Software Development Engineer with 1+ year of experience building backend systems and event-driven data pipelines. At Equity Brains, I engineered a scalable system running 100+ cron jobs and DAGs to pull real-time and historical stock data, with retry logic and rate-limit handling for reliability under high load.

I architected an event-driven Apache Kafka pipeline across 10+ topics, powering independent consumers for transformation, caching, and persistence—processing 50K+ records daily. I improved database performance by 40% using Redis caching and batched bulk writes, and applied polyglot persistence with MongoDB and PostgreSQL while containerizing 10+ microservices with Docker and exposing functionality via REST APIs.
