About Me
I started as a software engineer focused on backend systems and production reliability. Over 5 years, my work expanded from building microservices and distributed systems into designing AI-enabled products and reasoning about architecture at a system and business level.
At Packet Systems, I contribute to CrampasAI, an enterprise AI product spanning backend engineering, AI workflow design, and on-premise SaaS architecture. Before that, I built scalable microservices for Telkomsel's MyOrbit platform serving millions of users across Indonesia.
My work now increasingly sits at the intersection of engineering, architecture, product thinking, and business outcomes. I focus on translating complex requirements into decisions that teams can build on and organizations can rely on.

HOW I CREATE VALUE
Technology That Solves Business Problems
From strategy to execution, I work at the intersection of business objectives, architecture decisions, and engineering delivery.
Technology Strategy
Translate business objectives into technology initiatives, priorities, and execution plans that teams can act on.
Solution Architecture
Design scalable solutions that balance complexity, cost, security, performance, and maintainability without over-engineering.
AI & Automation
Identify practical opportunities where AI and automation create measurable product value, not just technical novelty.
Product & Engineering
Bridge product requirements and engineering execution to deliver reliable systems that are observable, maintainable, and production-ready.
Experience
Building real products through hands-on engineering work, with growing focus on product thinking and leadership

How I Think
The mental frameworks that guide decisions across architecture, AI, product, and engineering.
01
Business First
Technology should solve a meaningful business problem rather than exist for its own sake. The first question is always: what outcome are we trying to create?
02
Architecture With Trade-offs
There is rarely a perfect architecture. Good decisions balance scalability, complexity, cost, security, and delivery speed — and communicate those trade-offs clearly.
03
AI With Purpose
AI should create measurable value rather than simply being added because it is technically interesting. The question is always: does this actually improve the outcome?
04
Build for Operations
A production system must be observable, maintainable, secure, and operationally reliable. Shipping is the beginning, not the end.
05
People & Communication
Technology decisions need to be communicated in language understood by product, business, and engineering stakeholders. not just technically correct.
