What I Solve
High-throughput backends, API platforms, and the automation that keeps them running in production.

About
The short version — who I am and what I care about.
I've spent 10+ years building systems where downtime isn't an option — banking pipelines moving millions of records a day, telco middleware adopted company-wide, and CI/CD that gets faster over time. I work in Java, Python, Node.js, and Go, and I care as much about what happens after deploy as the code itself.
Where I Deliver
Banking payment rails, telco middleware, and enterprise data pipelines across Indonesia.
How I Work
Own problems end-to-end — architecture, code review, CI/CD, observability, and team growth.
Skills
Depth over breadth — tools I use in production, not a keyword dump.

Senior Software Engineer
PT Firstwap International
Own telco product modernization while pushing engineering-wide gains in delivery speed and security.
- Cut release cycles by 30% by overhauling GitLab CI/CD across multiple product lines.
- Led the company-wide SBOM program in Dependency-Track — component analysis and supply-chain visibility from build to audit.
- Host monthly tech sharing sessions; code reviews backed by SonarQube static analysis.
Selected Work
- On-Premise AI Platform — Local LLMs on NVIDIA DGX for policy-compliant code review — no data leaves the building.
- SCTP Library (Go) — Protocol library built from scratch; now the telco department standard.
Back-End Engineer / R&D
Telkomsigma
Shipped banking and BI infrastructure for Indonesian financial institutions at production scale.
- Launched Open API portals on Kong Gateway for Bank Kaltim & Kalbar with automated publishing.
- Supported BI-Fast go-live at Bank Maspion with Grafana/Prometheus observability.
- Owned high-volume core banking data pipelines — 1M+ records daily (see case study).

Freelance
Shipped Odoo ERP solutions for small businesses while completing a Computer Science degree.
Case Studies
Deeper dives into two projects where architecture decisions made a measurable difference.
Company-Wide SBOM Initiative
Context
As product portfolios grew across telco services, teams lacked a unified view of third-party dependencies — making vulnerability response slow and compliance audits painful.
Challenge
Introduce SBOM-driven component analysis across multiple product lines — without disrupting release workflows or treating vulnerability scanning as a bolt-on step outside the pipeline.
Approach
- Standardized on CycloneDX SBOM format and Dependency-Track as the central component analysis platform.
- Integrated SBOM generation and upload into GitLab CI/CD so every release is analyzed automatically via Dependency-Track's API.
- Configured vulnerability intelligence sources (OSV, NVD, OSS Index) inside Dependency-Track for automated component risk matching — not as a separate scanner.
- Established review practices alongside SonarQube static analysis and ran knowledge-sharing sessions on supply-chain risk.
Outcome
- Company-wide visibility into third-party components across all product versions in one portfolio view.
- Known vulnerabilities surfaced automatically through Dependency-Track's SCA engine — faster triage, less manual lookup.
- Stronger compliance posture with auditable SBOMs and policy-based risk tracking.
- SBOM upload became a standard CI/CD gate — component analysis runs on every release.
Side Projects
Personal experiments outside of work. Most of my professional output is closed-source — see Case Studies for that.
These are things I build on my own time to explore new stacks and ideas. They complement — not replace — the enterprise work described above.
Algorithmic Trading System
ActiveBuilding an AI-driven workflow to analyze live Forex & crypto markets, backtest strategies, and automate trade decisions. Currently in active development.
Blockchain Digital Certification
A permissioned blockchain app for issuing tamper-proof digital certificates — built on Hyperledger Fabric for enterprise private-chain requirements, with chaincode in Go (the language of the Fabric ecosystem on GitHub).
Telegram Community Bot
Automates group moderation and recurring admin tasks so community managers can focus on engagement, not busywork.
Odoo Migration (v8 → v10)
Led a full-version ERP migration with zero data loss and minimal downtime — an early deep-dive into production system upgrades.

Foundation and continuous learning — kept brief; experience speaks louder at this stage.
