Senior Software Engineer with BSc (Hons) and 4+ years of experience designing, building, and shipping production systems. I specialize in Java Spring Boot backends, API design, authentication/authorization (JWT), reporting pipelines, and CI/CD. I also deliver cross‑platform apps in Flutter and pragmatic web UIs with React.
My work spans ERP modules (PO, GRN, Invoicing, Stock, Accounting, Sales, Inventory), HRIS automation, real‑time geo solutions (GeoServer, QGIS, Leaflet), device integrations (ZKTeco attendance), payment gateways (Thawani, Square), and cloud deployments on AWS/Contabo with Cloudflare.
I value clean architecture, observability, and secure defaults; I write well‑structured APIs, craft reliable data models, and automate delivery through pipelines so teams can iterate faster with confidence.
