What I'm looking for

I'm open to Senior Java Backend roles, Technical Leadership positions, or consulting opportunities where I can combine my technical expertise with business optimization.

At Lunar TC, I architect and develop enterprise workflow services with Java 17 and Spring Boot. I optimized MongoDB queries and indexing to improve read performance by 40%, and redesigned execution paths for millions of workflow instances.

At Shell, I led the move from paper-based operations to automated software, including cash reconciliation, attendance tracking, and reporting that eliminated more than 15 hours of manual work per week. My background in optimization and decision support shapes how I approach software: I look for process bottlenecks and build solutions tied to practical business outcomes.
