Engineering Leadership & Enterprise Architecture
I am a BNSP Certified Senior Programmer and Tech Lead with over 7 years of professional software engineering experience (2017 – Present). My expertise lies in designing, scaling, and maintaining high-performance backend architectures, distributed RESTful APIs, and cross-platform mobile solutions.
Throughout my career at PT Mitreka Solusi Indonesia, PT Solusi Pembayaran Elektronik, and PT Maxxima Innovative Engineering, I have spearheaded the development of over 25+ mission-critical enterprise systems for Indonesian government ministries (ESDM, KUKM, POLRI, PPATK, PUSHIDROSAL, TNI AU) and tier-1 banking institutions (BNI, Bank DKI, Bank Permata QRIS).
Prioritizing modularity, maintainability, and clear separation of concerns across complex monorepos and microservices.
Passionate about tuning heavy SQL queries, indexing, and designing robust relational ERD schemas—proven to reduce data retrieval latency by up to 70%.
Guiding cross-functional engineering teams, enforcing strict coding standards, and negotiating client requirements to deliver on-time, compliant software.
