Associate Software Engineer at Rupeeseed Technology Ventures Pvt Ltd, Feb 2024 - Present · 2 yrs 6 mos, Mumbai, Golang Backend Engineer at a fintech product company — building and re-engineering the backend infrastructure powering live trading, investment, and payment platforms used by real users at scale. What I Do • Re-engineer systems in Go: Migrating performance-critical backend modules from legacy stacks to Golang — delivering measurable gains: 40–45% faster response times, 35% better scalability, 20% faster deployments. Go is my primary language and the lens through which I approach every backend problem. • Build payment infrastructure: End-to-end payment gateway integrations in Golang, Spring Boot, and Grails — BillDesk (JWE/JWS), Atom (symmetric encryption), HDFC UPI Intent (QR-based flow). Reduced integration issues by 30%, improved transaction success rates by 25%. • Distributed backend systems: Designing event-driven, high-throughput services using Apache Kafka, Redis, gRPC, and MySQL — built for reliability and low latency in a trading environment where downtime costs money. • Order Management System: Working with C-based IPC systems to process high-volume Buy/Sell orders from desktop trading clients — low-latency order execution with reliable status propagation across the stack. Key Projects Shipped in Production 1. Payment Gateways — BillDesk · Atom · HDFC UPI: − Rebuilt in Golang from Grails: 40% faster responses, 35% scalability improvement, 30% fewer integration issues. − Security hardened via JWE/JWS and symmetric encryption. HDFC UPI redesigned with QR-based flow eliminating SDK dependency entirely. 2. NSE Offer For Sale (OFS) Trading System: − Full lifecycle API development in Grails + MySQL: securities retrieval, order entry/modify/cancel, real-time tracking, NSE integration. − Core components migrated to Golang: 25% efficiency gain, 20% faster deployments, 30% improvement in operational accuracy.

Trainee Software Engineer at NeoSOFT, Jun 2022 - Jul 2023 · 1 yr 2 mos, Mumbai, • Independently built and delivered CRUD REST APIs using Spring Boot and MySQL — taking ownership of backend service design, data integration, and API reliability within an enterprise Java environment from early in my engineering career. • Led personal adoption of Microservice Architecture principles — implementing Spring Boot, Eureka, Config Server, API Gateway, Feign Client, and Docker to build modular, container-ready services with clean inter-service communication patterns. • Self-onboarded onto an enterprise Java stack with no prior exposure — reaching production contribution level rapidly, demonstrating the same self-sufficient learning approach I have since applied to Golang, gRPC, and distributed systems. Projects: Depositors Education and Awareness Fund Management System (DEAF) • Owned backend enhancement work on a Struts-based banking application — integrating Spring MVC and Oracle SQL Developer, aligning stored procedure mappings with the Data Access layer, and ensuring consistent behaviour across Struts and Spring MVC components. • Independently traced and resolved JSP frontend defects to their backend Controller origins — modifying components directly to restore correct request handling and fix broken page rendering across the application. • Took end-to-end ownership of WAR file deployment on Oracle WebLogic Server — managing the full development-to-deployment pipeline and ensuring application stability in a live banking environment. AlSudais For Trading & Transports • Owned Master Service module API development in Spring Boot, PostgreSQL, and Spring Data JPA — building Port Airport Master and Pack Type Master endpoints within an eight-member team, with all APIs validated through Postman and Swagger. • Designed and implemented server-side multi-language validation in English, Hindi, Urdu, and Arabic using RESTful Locale features and message.properties files — ensuring reliable international input handling across all client-facing service endpoint
