What I'm looking for

I want to lead full-cycle engineering, architect scalable systems, and collaborate with product teams to ship reliable, client-focused solutions—using modern frameworks and AI tools to improve quality and delivery speed.

I’m an experienced software engineering professional with over 9 years of expertise in full-cycle software development, architecture, and team leadership. I’ve built scalable applications and delivered solutions for government, banking, and corporate clients, using modern frameworks plus AI tools to optimize engineering workflows and meet business objectives.

At ERASYS CONSULTING as an Indonesia Technical Lead, I lead engineers through the full software development life cycle, from technical requirements to delivery. I architect and design scalable, maintainable systems and services, review code and set strict engineering standards, and work closely with product managers to align scope and project timelines.

Earlier in my ERASYS journey and across client work, I developed custom applications with Frappe and ERPNext, and built end-to-end automation frameworks using Playwright and TypeScript to reach 90% functional test coverage. I also enhanced digital banking platforms with SpringBoot and Apache Camel, built the Digital COVID-19 Contact Tracing platform (SIAGA) using Django, and improved mobile experiences with React-Native and Django; I’ve delivered payment auto-reconciliation using Java, Spring, and PostgreSQL, and supported mission-critical systems like Java/XML-based FEWS and Python-based TRIGRS for landslide early warning.
