PROFESSIONAL EXPERIENCE

Lead Software Engineer — Indomaret Group

Nov 2021 — Jan 2025

As a Lead Software Engineer (Junior Manager, Jan 2025–present; previously Supervisor, Nov 2021–Jan 2025), I lead end-to-end delivery across Indopaket’s Android, iOS, Huawei apps and website, steering cross-functional teams from build to production. I designed the database and APIs for a high-impact referral program tailored for Seller Idaman members and lifted app and web performance by optimizing our caching layer with Valkey (Redis). I shipped a Bank Indonesia–standard i.saku payment integration with voucher/discount mechanics, and built a scalable CMS to manage dynamic content across platforms. To raise engineering velocity and integration quality, I established a technical documentation site and an API/Android integration hub. I also partner closely with marketing and operations to turn business needs into clear, testable system requirements and even contributed to Indopaket’s brand mascot to strengthen our visual identity.

Management Development Program Specialist — Indomaret Group

Nov 2020 — Nov 2021

I lead cross-functional web teams to deliver scalable internal systems that streamline workflows and boost productivity. I launched indopaket.co.id to strengthen Indopaket’s digital presence and make services easier to access. I mentor interns and junior developers in Laravel, Flutter, and MySQL, enforcing clean code and on-time delivery. I also defined and rolled out a pragmatic SDLC framework that raised engineering standards and accelerated execution across the WebApp team.

Website Developer Intern — PT Bank Central Asia Tbk

Ags 2019 — Jan 2020

I deliver end-to-end solutions that turn operations into measurable outcomes: built a .NET platform to track and analyze employee workload for smarter resource planning; developed a Laravel internal system with real-time dashboards to monitor operations and support manual QA; authored clear technical documentation, led testing, and owned production deployments; and created Excel/VBA macros that streamlined QA workflows in a regulated banking environment reducing manual effort and improving testing reliability.

Assistant Lecturer — Universitas Kristen Duta Wacana

Jan 2017 — Apr 2019

As a Teaching Assistant, I led and mentored hands-on labs across core computer science courses: Fundamentals of Programming, Algorithms & Data Structures, Web-Based Programming, Database Systems & Design, and Multimedia. I supported students one-on-one and in groups, clarified concepts, unblocked lab work and assignments, and raised the overall quality of projects. I also co-created lab modules, contributed to clear grading rubrics, and collaborated closely with lecturers to deliver a cohesive, outcomes-driven learning experience that strengthened both technical depth and real-world readiness.
