What I'm looking for

I'm looking to build high-impact fintech, trading, or real-time platform systems where I can work on scalable backend infrastructure, low-latency data processing, and product features that reach users.

At Aargo Trade, I build real-time trading infrastructure, including a trade reconciliation system that validates broker logs against internal ledgers and removes manual discrepancies.

I also designed a Python and AWS SES communication platform that sends 10K+ targeted emails in under 10 minutes, and improved core fund infrastructure with Redis-backed, low-latency processing. I built an event-driven referral and rewards engine for a global prediction market launch.

Previously at Aryvo, I built flight tracking for airport rides that reduced late pickups by 20%, alongside Java and Spring Boot APIs for fleet operations and Vue.js workflows for drivers.

As a founding engineer at Flash.co, I shipped growth and user-platform features that helped scale the app from 0 to 200K+ users. I also built internal tools, migrated infrastructure to AWS EC2, and created Tickr, a live stock screener using Zerodha's KiteConnect API.
