Solution Architect | Java & Spring Boot Microservices | AWS/Azure | 15+ Yrs | Tech Leadership

About

I'm a Solution Architect with 15 years of hands-on expertise building and scaling enterprise systems that handle real complexity: microservices migrations, event-driven architectures, and cloud-native transformations. My focus: Moving fast without breaking things. I design systems that balance innovation with reliability—leveraging Java, Spring Boot 3.x, Apache Kafka, Kubernetes, and cloud platforms (AWS/Azure) to solve hard problems. I'm equally comfortable in a HLD/LLD meeting, architecting Kafka clusters, or mentoring teams through a Spring Boot upgrade. Recent work: • Led Spring Boot 2.7.18 → 3.4.6 migration for enterprise applications, reducing boot time by 30% and unlocking reactive programming • Architected event-driven systems with Apache Kafka (KRaft mode), handling 1000+ concurrent users with sub-100ms latency • Designed and implemented microservices solutions serving multiple business units; 40%+ improvement in API response times through caching and database optimization • Mentored 4+ junior developers and tech leads on architectural patterns, SOLID principles, and distributed systems design • Drove technical RFP evaluations and POC work for cloud platforms and integration frameworks I thrive when architecting from scratch, modernizing legacy monoliths, and building high-performing teams. Currently seeking Solution Architect or Senior Technical Lead roles at product companies or top consulting firms where I can own architecture decisions and drive innovation.
