At Lexplosion Solutions, I've architected RegTech platforms including Komtrol Plus, building microservice foundations, a reusable multitenancy Core library, and a custom Spring Cloud API Gateway.

I've built crash-tolerant market-data ingestion, document pipelines integrating Microsoft Graph and Google delta APIs, and compliance workflow engines. My work spans Spring Boot, MySQL, MongoDB, Redis, ClickHouse, AWS, and Vue.js, including a freelance full-stack recruitment platform for NexpertsJobs.
