About Me

my Impact & Vision

I build scalable products by combining software engineering, AI, and product thinking.

I'm a Software Engineer from Indonesia with 6+ years of experience shipping production software across fintech banking, AI media generation, automation, and indie products — from frontend and backend to cloud infrastructure and AI-assisted development.

At CFactory Indonesia, I co-founded gamgen.ai and won the pitch to build Telkomsel's Q3–Q4 2025 generative campaign platform. At Syaria Finance Bank HIK Cibitung, I boosted digital payment revenue by 4–7% through microservices and established the bank's first CI/CD and SonarQube pipeline.

Since 2022, I've also led Radkai Studio — a community-supported indie workshop shipping cross-platform apps to Google Play and the web. My work has been recognized on Google Play's Success Story page.

Engineering Workflow

how do I Manage the Things
Frontend Engineering

I build responsive, scalable user interfaces with React, Next.js, TypeScript, and React Native. My focus is on usability, performance, and delivering polished user experiences while maintaining clean, maintainable code.

Backend Engineering

I design secure, scalable backend services, APIs (REST/GraphQL), and database architectures with Node.js, FastAPI, and Laravel. I focus on reliable business logic, efficient data management, and seamless cloud integrations.

Optimization and Testing

I prioritize performance, reliability, and maintainability. I optimize queries, application performance, and infrastructure while implementing unit, integration, and end-to-end (TDD/E2E) testing to ensure production-ready software.

Documentation

I write concise, practical documentation that supports collaboration and long-term maintainability. This includes technical documentation, API references, architecture notes, and developer guides.

DevOps & Automation Engineering

I build and maintain delivery infrastructure: containerized environments with Docker, CI/CD pipelines, static analysis gates like SonarQube, YAML-based configuration, and cloud deployments across AWS and Google Cloud — with monitoring and release reliability baked in.

AI-Assisted Development

I leverage AI throughout the entire Software Development Life Cycle using Claude, Codex, and Gemini — from requirements analysis and system design to implementation, testing, debugging, and code reviews. Experienced with BAML, MCP, AI agents, and automation workflows to deliver high-quality software faster without compromising engineering standards.

Communication

I communicate effectively in English (EF SET C2) and Bahasa Indonesia (native). Experienced working in remote, international teams, I collaborate with engineers and business stakeholders to translate ideas into technical solutions.

Skills

AI Tooling & Automation

how I Accelerate Productivity
Frontier Models
Frontier Coding Agents

I pair with frontier LLMs as daily engineering collaborators across the full software development life cycle — from requirement discovery and architecture to implementation, refactoring, testing, and code review.

  • Claude
  • Codex
  • Gemini
  • Multi-Model Workflows
Harness & Orchestration
Model Harnesses & Agentic Tooling

Rather than one-off chat prompts, I run frontier models through custom harnesses and agentic runners so several models can be orchestrated, chained, and supervised on real production tasks.

  • Model Harnesses
  • Pi
  • OpenClaw Agentic Tooling
  • Supervised Autonomy
Automation
Automation & Scheduling

I turn recurring engineering and business operations into reliable automated pipelines by wiring APIs, event triggers, and schedulers — removing manual, repetitive work from the critical path.

  • n8n
  • Microsoft Power Automate
  • Grok Bot
  • API & Event Triggers
Research & Planning
Deep Research & Blueprinting

Before committing to a build, I use maximum-depth research models to produce architecture blueprints, technical plans, and requirement documents — combining multiple frontier models to pressure-test decisions.

  • Codex Astra
  • Architecture Blueprints
