Fullstack developer with 9 years shipping multi-tenant SaaS solo — backend, web, mobile, infra, and the UI/UX in between. I don’t hand off the design; I own it.
Every project below carries a stack strip showing which layers I personally designed and built. Most are end-to-end.
Product flows, design systems, hi-fi prototypes — not just dev-grade screens.
React, Svelte / SvelteKit, TypeScript — dense, fast enterprise UIs.
Flutter apps with geofencing, clock-in, and offline-friendly flows.
Go, .NET, Laravel, Bun/Hono — multi-tenant domains, events, approvals.
PostgreSQL / MySQL — versioned schemas, migrations, encryption, pgvector.
GCP, Azure, Docker, Jenkins, Caddy — CI/CD, deploys, secrets.
Real platforms in production across HR, recruitment, F&B, fintech, and community — each one designed, built, and deployed.
A multi-tenant HRIS for Transklin Indonesia — 1,472 active staff across client sites, with selfie clock-in, shift scheduling, leave, and payroll. Built solo end to end, then re-architected from a Laravel monolith to a Go + React + Flutter platform while staying live.
Large-scale WMS for a multi-outlet F&B group (Hachi Group) — inventory, stock movement, recipe-based production planning, multi-warehouse transfers, and supplier procurement — handling high-volume data with queues and scheduled jobs.
Recruitment SaaS handling sensitive candidate data — CVs, salary, PII. AI CV Autofill (GPT-4o-mini) cut manual entry ~80% and scores CVs for ATS-friendliness. Client-side envelope encryption via Azure Key Vault and GCS signed-URL access, aligned with Indonesia’s UU PDP.
A WhatsApp chatbot for a money changer (Dolarindo) — customers pick a language, check live exchange rates, and start transactions in chat, while staff manage orders, branches, and every logged conversation from a Laravel admin panel. ~300 transactions/month on the WhatsApp Cloud API.
A discipleship and community-management platform built for Domus Cordis, a Catholic community — organizes members into cell groups and tracks gathering attendance, spiritual habits, and a reviewer-scored LMS. Role-based access and full multi-language (i18n).
Production work without a full case study here — real, shipped, and part of the picture.
Internal employee forum app for HR communications. Native Android (Kotlin) and iOS (Swift) with a Vue.js back-office and Laravel backend — built solo, end to end, directly with HR stakeholders.
Picked per problem, not per trend — backend and infra are home base, design is a deliberate choice.
I’m a fullstack developer based near Bogor, West Java, building enterprise software at KST (Jakarta) and running my own studio, Kangkode, for independent work.
My focus is HR and workforce platforms and other multi-tenant SaaS — the kind of product where one person has to be comfortable from PostgreSQL migrations all the way up to the design system. I treat UI/UX as part of engineering, not a separate phase, and I care about deployments that actually survive production.
Currently open to international freelance and full-time roles.
Backend, mobile, or a whole product from zero — I can take it from architecture to a shipped, designed, deployed system.
