Software Engineer @ Card91 | Java, Spring Boot, React.js, TypeScript | Fintech & Payments | Immediate Joiner

About

I build the backend infrastructure and API contracts that power financial systems—where "mostly working" isn’t an option. In fintech, latency spikes, state mismatches, and unhandled edge cases directly affect real money, user trust, and reliability. At Card91, I engineer backend flows for a multi-currency payments platform covering card management, approval workflows, exchange-rate lookups, and payment integrations. I’ve implemented 20+ RESTful APIs using Java and Spring Boot, supporting 15,000+ daily multi-currency transactions. A major focus of my work is backend performance. By introducing Redis distributed caching alongside Spring Data JPA and MySQL, I reduced database query load by 35% and cut API latency from 220ms to ~85ms. I’ve also built secure Razorpay Payment Gateway integrations across microservices, prioritizing reliable transaction flows and real-time status tracking. My engineering approach combines hands-on production experience with strong CS fundamentals, backed by a Master's of Science in Computer Science from Queen Mary, University of London. While my core focus is backend engineering with Java, Spring Boot, REST APIs, and Microservices, my experience with React.js and TypeScript gives me a strong grasp of the full application flow. Understanding how frontend applications consume API data allows me to design cleaner contracts and smoother client-backend integrations. Here’s what defines my engineering approach: 🔹 𝐂𝐨𝐫𝐫𝐞𝐜𝐭𝐧𝐞𝐬𝐬 𝐎𝐯𝐞𝐫 𝐒𝐡𝐨𝐫𝐭𝐜𝐮𝐭𝐬: In financial systems, edge cases matter. I build reliable services that behave predictably under real-world conditions. 🔹 𝐏𝐫𝐨𝐝𝐮𝐜𝐭-𝐀𝐰𝐚𝐫𝐞 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠: I look beyond tasks to understand product workflows, consumer impact, data security, and production behavior. 🔹 𝐅𝐮𝐥𝐥-𝐒𝐭𝐚𝐜𝐤 𝐀𝐥𝐢𝐠𝐧𝐦𝐞𝐧𝐭: My frontend background helps me design APIs that make client integration simpler and more efficient. 🔹 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐎𝐰𝐧𝐞𝐫𝐬𝐡𝐢𝐩: I care about code post-merge—from JUnit testing and peer reviews to Grafana monitoring, troubleshooting, and CI/CD pipelines. ⚡ 𝐀𝐯𝐚𝐢𝐥𝐚𝐛𝐢𝐥𝐢𝐭𝐲: Available to join immediately . 🎯 Whether optimising payment flows, building Spring Boot microservices, improving API performance, or designing clean service contracts, I focus on reliability, scalability, and measurable impact.
