What I'm looking for

I’m looking for a team where I can build scalable full-stack systems, integrate APIs, and ship with urgency—while collaborating closely with PMs, designers, and stakeholders in an empathetic, trust-building process.

I’m a Full Stack Engineer with 5+ years of experience building and connecting technology systems for enterprise clients and multinational teams in Indonesia, including government entities. I’ve worked in both a system integrator and an agency in a hybrid setup, taking responsibility for building scalable systems and integrating multiple technologies. I bring an empathetic approach that helps clients and teams feel heard and builds trust throughout delivery.

In my last role at PT. EMIFLY TEKNOLOGI SOLUSI (ETS), I built ERP system modules supporting 1,000+ daily concurrent users and 70,000+ transactions per day. I implemented real-time reporting scripts that reduced manual workload by 90% and improved data accuracy by 24%, and I created an RPA system that cut manual processing time by 95%. I also integrated an API payment gateway handling 2,700+ transactions per day, reducing errors by 17%, and I led a team of 8 to deliver products to clients on schedule.

I’m comfortable working across the product workflow with product managers, business analysts, and designers, communicating effectively with both technical and non-technical stakeholders. Alongside full-stack delivery, I’ve created user guides, API docs, and guides using Markdown and Swagger, and I’ve contributed as a Junior Web Developer on a Django-based CMS. Whether it’s building high-traffic experiences with Next.js and AWS or improving performance with caching and CDN strategies, I work with urgency and can manage tasks without close supervision.
