About Mohan S

I’m a Java Full Stack Engineer with 4+ years of experience building scalable, high-performance applications across fintech, marketplace, and enterprise platforms. I enjoy solving complex engineering problems and turning them into reliable, production-ready systems that scale.Currently, I work as a Software Engineer at Uber, where I enhance Java 17 and Spring Boot microservices powering distributed marketplace workflows. By improving service orchestration across multiple REST and asynchronous endpoints, I help maintain fault-tolerant processes across critical business systems. I’ve also leveraged AI-assisted development tools to reduce debugging time and accelerate developer onboarding by 32%, while improving test scaffolding efficiency by 22%. Before Uber, I built and optimized backend systems and full-stack platforms used by thousands of users. At Milestone Technologies, I engineered secure payment modules handling 50K daily transactions, optimized PostgreSQL queries to reduce endpoint latency from 3.8s to 1.5s, and implemented Kafka-based event streaming to improve system scalability and resilience. At Dell Technologies, I led development of enterprise customer management modules supporting 1.2M monthly transactions, improved query performance by 35%, and helped maintain 99.9% uptime for mission-critical services used by global stakeholders. My technical toolkit includes:• Backend: Java (8–21), Spring Boot, Microservices, REST APIs, Hibernate• Frontend: React.js, Redux, Angular, TypeScript• Data & Messaging: PostgreSQL, MongoDB, Apache Kafka• Cloud & DevOps: AWS, Docker, Kubernetes, Jenkins CI/CD• Engineering Practices: Agile development, automated testing, distributed system designI’m passionate about building scalable cloud-native systems, improving developer productivity, and designing architectures that support high-volume real-world workloads.Long term, I aim to continue growing as a senior engineer and system architect, leading the design of large-scale distributed systems that power modern digital platforms.If you’re working on scalable systems, cloud platforms, or high-impact engineering challenges, I’d love to connect and exchange ideas.
