Backend developer focused on Node.js automation, web scraping, exploit detection, and API abuse techniques. I turn complex problems into clean, working systems.
01 / About
I'm a self-taught backend developer with a deep specialization in Node.js and Lua. I don't just write code — I reverse-engineer systems, find patterns where others don't look, and build automation tools that solve real problems.
My work spans from building full-scale student management platforms deployed in real Indonesian schools, to writing Lua exploit scripts for games, SSL unpinning tools for mobile apps, and Tapjoy offerwall automation engines.
Automation is not a feature — it's a mindset. If a task can be automated, it should be. If a system has a weakness, it's worth understanding. I build tools that are observable, resilient, and purpose-built.
I design systems that work while you sleep — from offerwall automation to event-driven pipelines that handle thousands of operations without manual intervention.
Finding weaknesses in web applications, detecting abnormal API patterns, and building tools that intercept and manipulate HTTP traffic for analysis and testing.
Architecting robust, resilient scrapers using Puppeteer and Cheerio with anti-detection strategies, proxy rotation, and SSL unpinning for deep-level inspection.
Crafting backend systems with Next.js, Node.js, MongoDB, and RESTful APIs — including full-scale platforms like SIMANIS and automated top-up systems.
Writing Lua scripts for Growtopia and Roblox — from game automation to exploit scripts, covering both gameplay mechanics and client-side behavior manipulation.
Using Frida, mitmproxy, and custom tooling to intercept mobile app traffic, bypass certificate pinning, and analyze encrypted API communication.
02 / Skills
Years of hands-on engineering, problem-solving in production environments, and relentless tinkering.
03 / Projects & Scripts
Full-stack platforms, automation engines, game scripts, and security tooling — all built for real use.
Sistem Manajemen Informasi Siswa
A comprehensive student information management platform deployed in real Indonesian schools. Handles student profiles, barcode-based attendance, disciplinary records, achievements, and automated WhatsApp notifications to parents.
Multi-Game Auto Top-Up System
An automated multi-game digital top-up platform with full order lifecycle management. Payments via Trakteer (GoPay, QRIS, DANA, ShopeePay), automated fulfillment via Tapjoy offerwall engine, and real-time order tracking.
Automated Gem Earning Engine
Node.js automation engine that programmatically interacts with the Tapjoy offerwall to deliver in-game currency. Parses offerwall HTML with JSDOM, submits completions, and uses game-specific userId obfuscation strategies to bypass duplicate-submission checks.
Game Automation & Exploit Scripts
Lua scripts for Growtopia covering auto-farming, world botting, item dupe detection, and client-side behavior manipulation. Targets game logic at the packet and memory level to automate repetitive in-game tasks.
Executor Scripts & Game Exploits
Roblox exploit scripts written in Lua targeting specific games. Covers aimbot, ESP, speed hacks, remote spy, and game-specific mechanic abuse. Compatible with popular executors and designed for detection evasion.
Certificate Pinning Bypass
Frida-based SSL unpinning scripts targeting Android and iOS apps. Hooks into the app's certificate validation logic at runtime to bypass pinning and allow traffic interception via mitmproxy or Burp Suite.
API Traffic Analysis & Replay
Node.js tooling for intercepting, logging, and replaying HTTP/HTTPS API requests from mobile apps and web clients. Useful for reverse-engineering private APIs, analyzing request signatures, and automating interactions with undocumented endpoints.
