Innovative Software Solutions to Build a Connected {World}

Open-source Rust implementation of the Zod validation library, published on crates.io with 50+ GitHub stars. Type-safe, zero-dependency schema validation with rich error reporting and built-in Axum integration, adopted as the validation layer in my production backends.

A custom-patched fork of Chromium for containerized web scraping, with surgical C++ patches that eliminate hardware-absence fingerprints (WebGL strings, media devices, WebRTC leaks) that off-the-shelf stealth tooling cannot fix. Orchestrated by a Rust workspace that validates and launches coherent fingerprint profiles, with an LLM-assisted profile authoring loop.

An interactive AI coding assistant for the terminal and desktop, written in Rust. Runs an autonomous tool-using loop with a permission system, parallel tool execution via Tokio, automatic 4-stage context compaction, and native support for Anthropic plus any OpenAI-compatible provider.

AI-powered video ad platform for Indonesian SMEs: merchants paste a Shopee or Tokopedia product link and get a ready-to-post TikTok-style narrated video in minutes. Built as Rust gRPC microservices behind an HTTP gateway, with a credit/subscription billing system (Midtrans), a WhatsApp Cloud API bot, and an admin dashboard.

Persistent memory for AI coding agents, running entirely on Cloudflare edge infrastructure. Every coding session is captured, distilled by Workers AI, embedded into Vectorize, and recalled in future sessions — with durable "lessons" that reinforce as they recur. Rust compiled to WASM on Workers, with D1, R2, and an MCP server for semantic search.

A reconnaissance framework that maps what an application is built on and what it talks to: point it at a site and it returns the tech stack, the private API, the auth scheme, and a generated OpenAPI document. Reads served HTML or drives a real browser to record post-hydration traffic, and can unpack mobile APKs including native libraries.

A Rust CLI and MCP plugin that lets AI coding agents on one machine (Claude Code, Cursor, Aider, and others) talk to each other — spawning agents under a pty or driving ones already running in tmux, then running a propose/critique/revise loop across them for mutual correction.

A Gemini-powered voice engine in Rust covering TTS, STT, and full-duplex realtime conversation over the Live API — with a fully offline Whisper + Piper fallback that needs no network or API key. Structured as a hexagonal Cargo workspace.

Converts natural language into real browser automation using AI vision that "sees" pages like a human — click "the blue login button" instead of maintaining CSS selectors. Three execution modes (DOM, Vision, Hybrid fallback) with live color-coded process logs.

A production-ready Rust backend boilerplate with Clean Architecture and DDD: JWT auth with refresh tokens, TOTP two-factor, Google OAuth, rate limiting, OpenAPI docs, and type-safe SQL with SeaORM. Published with a live documentation site and used as the reference architecture for my backend work.

A complete full-stack SaaS starter: TanStack Start with React 19 SSR, oRPC + TanStack Query, better-auth with Google OAuth, multi-tenancy with role-based access control, PostgreSQL + Drizzle, Redis, and English/Indonesian i18n — reproducible dev environments via Nix devenv or Docker.

A modular open-source pagination library for Rust with page-based, offset, and cursor (keyset) strategies, 14 filter operators, full-text search, and SQL-injection-safe database integrations. Ships with a documentation site.

One declarative Nix flake managing my entire fleet: NixOS workstations, macOS via nix-darwin, and VPS hosts deployed with nixos-anywhere — including self-hosted services (n8n, Uptime Kuma, Netdata, error tracking) defined as code. Every machine is reproducible from a git clone.

Full-stack exam platform delivered for a client in a 4-month cycle: a modular React 19 frontend in an Nx monorepo with role-based access and test-driven development, backed by a Rust API built with Axum and SurrealDB with full integration test coverage.

Scalable modular platform for a national property brand, built with Next.js and an Nx monorepo. Contributed to the shared design system, optimized build pipelines, and enabled cross-team collaboration across multiple products.

Web3-enabled voting system for university presidential elections, built on Next.js and Solana with 100% vote integrity and a mobile-first UX.
