Software Engineer at Devsoul Technologies (Pvt.) Limited

February 1, 2026 - Present

Building Fremlo, a social-commerce marketplace combining a classifieds engine with a social-style feed. Works end-to-end using NestJS, Next.js (React/Redux), TypeScript, PostgreSQL, Redis, Kafka, and Elasticsearch. Delivered core modules including listings with search and filtering, personalised feed, real-time chat, seller ratings and trust, and content moderation. Designed an event-driven architecture where API writes publish domain events to Kafka; async workers handle feed fan-out, notifications, and search indexing to keep request latency low. Used Redis for feed timelines and caching, Elasticsearch for full-text and geo search, and S3 presigned uploads for media.
