About
Jalu Pradipta is a backend developer based in Surabaya, Indonesia. He works at PT Shelter Indonesia as the backend developer of CAIS, the company's internal ERP, and builds business systems in Laravel and Go.
D3 in Telecommunication Engineering from PENS, Surabaya. I joined an internal ERP at SHELTER as an intern in 2025 and am now on staff as its backend developer — 1,203 of its 1,305 commits, alongside six other people. Before that I mostly learned by breaking things in production and then having to explain why.
I am most useful on the parts nobody volunteers for: document numbering that must not collide, wage rules that follow actual labour regulation, approval flows where a signed contract cannot quietly change.
What I work in
Listed by how much I have actually shipped in it, not by how it looks on a CV.
Laravel 12 · PHP 8.2 · MySQL · Laravel Sanctum · REST + OpenAPI
75,500 lines of production ERP live here.
Go 1.25 · Fiber · PostgreSQL · sqlc
One API in production use, repository layer generated from SQL.
React 19 · Redux Toolkit · Vite 7 · Tailwind 4
Enough to ship my own clients, including this page.
Flutter · Dart 3.10 · Riverpod · go_router
10,856 lines across ten enforced feature modules.
Docker · GitLab CI · Kubernetes · nginx · AWS S3
Images built in CI, probes that actually probe something.
Track record
Dates are what they are.
D3 Telecommunication Engineering, PENS
Three years on networks, telecommunication systems, and information technology in Surabaya. Graduated 2025 with a 3.48 GPA. The degree is not software, which turned out to matter less than knowing how systems fail.
National finalist, KRTI
Kontes Robot Terbang Indonesia, held at ITERA Lampung. Fixed Wing division, on electrical — my job was that every component on the aircraft still worked when it left the ground.
Started writing software seriously
Programming stopped being coursework. Automation, system integration, and the specific satisfaction of a problem that stays solved.
Narrowed to backend: Laravel and ERP
The Laravel ecosystem, REST API design, and how a business system is actually laid out. First ERP-shaped applications, none of them in front of a paying user yet.
Graduated PENS, backend intern at PT Shelter Indonesia
Straight from the degree into CAIS ERP on Laravel 12, plus Smart Warehouse research using a genetic algorithm over MQTT.
Backend developer, PT Shelter Indonesia
Taken on as staff to keep building CAIS ERP. 1,203 of its 1,305 commits are mine, and it runs in production with the sales team every day.
