Featured Projects
A selection of products and tools I've built — for clients, for SMEs, and for myself.
Nusakit API — Indonesian Data Validation
REST API for validating and formatting Indonesian data — NIK (KTP), NPWP, phone numbers, Rupiah (with terbilang), bank accounts, and wilayah (administrative regions). Built on Cloudflare Workers + D1 for sub-50ms response times at the edge. Free tier with no signup, used by 100+ developers.
Actuarial Copilot — AI Agent with Domain-Specific Tool Calling
AI-native research and calculation assistant that combines RAG over a curated regulatory knowledge base with an agent loop calling 13 production-grade domain calculators. Built as a showcase of production AI engineering — eval-driven development, hybrid retrieval, tool calling architecture, and expert-in-the-loop validation.
CV ATS Generator — Build CVs That Pass Automated Screening
Browser-based CV builder that scores resumes against ATS algorithms in real time. Pick a template, fill in structured sections, and get instant feedback on keyword coverage, formatting issues, and readability — then export as print-ready PDF. No sign-up, no server-side storage, everything stays in the browser.
Warkas — Warung Kasir SaaS
Multi-tenant point-of-sale platform built for Indonesian micro-businesses (traditional warungs and street-food vendors). Replaces handwritten ledgers with a phone-friendly POS that tracks sales, stock, and daily revenue without needing a laptop. Each warung gets an isolated workspace with its own staff accounts and inventory.
Code Auditor — Automated Security & Code Quality Review
Developer tool that runs LLM-assisted reviews on a pull request: security issues, anti-patterns, missing error handling, and obvious code smells. Built to catch the things humans miss in late-night reviews — and to give solo developers a baseline second opinion they don't have a teammate to provide.
Alya Bakery — Storefront & Order Management
Online storefront for a home-bakery business. Customers browse the catalog, customize cake orders (size, flavor, add-on toppings), and check out via WhatsApp deep-link. Owner-side dashboard tracks pending orders, ingredient stock, and a basic accounting view of daily revenue.
Kirim WA — Self-Hosted WhatsApp Gateway
Self-hosted WhatsApp Business gateway for sending order confirmations, OTPs, and broadcast messages from your own infrastructure — without paying per-message to a SaaS gateway. Pairs a phone via QR code, queues messages through Redis, and exposes a simple REST API.
SIMANTRA — Real-time Anti-Trafficking Dashboard
Government-facing dashboard that aggregates anti-trafficking case data across regions and renders it as live visualizations: case counts by province, victim demographics, trafficking-route patterns. Uses LLM-powered text classification to categorize incident reports as they arrive.
RangkumanUT — UT Module Summarizer
Reading companion for Universitas Terbuka students. Uploads PDF modules and produces structured summaries, key-term glossaries, and practice questions. Reduces the time it takes to skim a 200-page module from a full evening to about 30 minutes.
Scriby — Audio Notes for Students
Lecture recording app that transcribes audio in real time, generates a structured outline, and lets students search across all their recordings by keyword. Built for students who are too busy taking notes to actually listen.
Metavase — Digital Agency Site
Marketing site and lead-capture funnel for a Jakarta-based digital agency. Service catalog, case studies, and a contact funnel that routes inbound leads to the right team based on project type and budget signals.
Incenplus — Corporate Site
Corporate website for an incentive and travel program operator. Showcases program packages, destinations, and testimonials, with an inquiry form that captures program type, group size, and preferred dates.
Karenabangunpagi — Coffee Brand Site
Brand site for a specialty coffee subscription. Tells the brand story, explains the subscription model, and offers a simple sign-up flow. Designed to feel like opening a slow-brewed Sunday morning.
NGKPS Depok — Church Community Site
Public-facing site for a Depok-area church community. Service times, sermon archive, ministry directory, and an events calendar. Designed to be edited by non-technical volunteers via a simple CMS.
Wahid Foundation — Nonprofit Profile
Public site for the Wahid Foundation, a nonprofit advancing tolerance, peace, and women's empowerment in Indonesia. Showcases programs, impact reports, news, and donation pathways.
