I build scalable Java backend APIs, payment integrations, and cloud-ready applications.
IndiaWhat I'm looking for
I've built scalable Java APIs and backend platforms for Lexicon Networks and CosmostakeR using Spring Boot, Hibernate, PostgreSQL, and MySQL.
At Lexicon Networks, I integrated Stripe subscription payments and secure webhooks for Finnector, upgraded the platform from Spring Boot 2.3.2 to 3.5.3 and Java 8 to Java 21, and implemented Redis query caching to reduce database load and improve API response times.
For Solar CRM, I developed a multi-module monolith for advanced reporting, optimized Java methods and SQL queries, and introduced SonarQube to improve code quality and maintainability.
Previously at CosmostakeR, I delivered payment, payout, Firebase, Twilio, WhatsApp, reporting, and automation capabilities across invitation, quiz, food-delivery, and retirement-planning products. I also led a move from AWS to Railway.app that reduced deployment costs by 70%.
