Candra Sudirman

I've built and operated Go microservices for Ako Media Asia's digital payments platform, unifying third-party providers behind a single transaction API. I also designed Reknota's event-driven order, payment, and notification services using Go, gRPC, GraphQL, MongoDB, and NATS.

At Bridgenote Asia, I owned REST APIs for accounting and inventory products, reduced database load by roughly 40% through query optimisation and Redis caching, and was promoted to Team Lead within 18 months. I led sprint planning and code review across a seven-person delivery team while shipping a mobile-facing API.

I've migrated legacy CodeIgniter and Laravel systems toward modern services without disrupting payroll cycles, payment flows, or other live operations. My work includes payment integrations, banking-platform upgrades, e-sports media services, consumer credit APIs, and high-volume spreadsheet processing.

I own services from design and delivery through monitoring and on-call support, and I've published open-source Laravel packages alongside Flockyn Spreadsheet, a Go library and CLI for streaming multi-million-row spreadsheets in constant memory.
