Omkar Gupta — Software Engineer

Backend engineer with 3 years of experience building Java Spring Boot microservices and React microfrontends for distributed payment systems. At NatWest, I own a platform of 4 microfrontends and 18 microservices, supporting 1M+ secure transactions monthly, with a focus on reliability, system stability, and production ownership. I contributed to a ~20% reduction in payment failures and designed a configuration-driven deployment approach within Spring Boot that reduced end-to-end testing time by ~50% and eliminated manual configuration errors, enabling consistent releases across environments. Alongside this, I’m building a new scheduler microservice to improve system-wide observability and transaction tracking, strengthening how issues are monitored and resolved across services. I've contributed to the HLD and LLD for the microservice. I’ve handled high-pressure production scenarios involving cross-team dependencies, certificate renewals, and system instability — ensuring continuity for systems processing millions of transactions daily, while also reducing potential security risks. My work spans distributed systems, REST APIs, CI/CD automation, and system design, with a strong focus on ownership, debugging complex issues, and making systems production-ready. I’ve also improved test reliability across services (80–90% coverage) and previously built cloud-based solutions including a Spring Boot WhatsApp chatbot (~25% engagement) and serverless applications on AWS. Outside work, I’m an IEEE-published researcher and enjoy writing, swimming, fashion and cooking. Currently focused on deepening my expertise in distributed systems and scalable, reliable platform design.
