👋 Hi, I'm Vanszs

Full-Stack, AI/ML, Blockchain Dev · Indonesian Student · Serial builder of "ecosystems" that probably should've been one app

"I'm not the smartest in the room — but I'm stubborn, and I have a lot of coffee." ☕

A student who can't sit still: if there's a real problem, I build the software for it; if there's an API, I automate it; if there's a competition, I enter it. My home turf is full-stack web (Next.js + TypeScript) and Python (trading, ML, automation), with frequent road trips into Flutter, Solidity, MQL5, and even ROS 2 for drones.

• 🎓 Currently writing my thesis (and occasionally helping friends with their ML projects)
• 🧩 I like shipping things end-to-end — from database and API to the UI people actually click
• 🤖 I treat AI as a coworker, not a threat — and enjoy building tools that wire into LLMs
• 🌱 Always poking at something new: web, mobile, trading, ML, security, a bit of robotics
• 😅 Honest disclaimer: several of my repos are forks I learn from or extend (clearly tagged below)

An early-warning system that flags students at risk of dropping out (elementary/middle school), built for the LIDM ITDP competition. It detects risk from attendance, grades, and economic factors — then suggests interventions, not punishment.

• Stack: Next.js 15 · TypeScript · Prisma 6 · PostgreSQL/PgBouncer · Auth.js v5 · Recharts · PWA (Serwist + Dexie)
• Highlights: a deterministic rule-based scoring engine (ABC framework: Attendance/Behavior/Course + local context), offline-first with a sync queue + idempotency keys, RBAC, AES-GCM encrypted backups, and a Dapodik CSV/Excel importer.
• 😅 An app that saves kids from dropping out, with a README longer than the kids' actual essays. Ships with Docker and audit logs — enterprise software for schools whose wifi flickers.

A router/proxy that connects AI coding tools (Claude Code, Cursor, Codex, etc.) to 40+ providers with auto-fallback and RTK token compression (saves 20–40%).

• Stack: JavaScript/Node · Next.js (server) · Python · Docker
• Highlights: per-API-key ACL, 3-tier fallback (subscription → cheap → free), Windows support that actually works (cmd/PowerShell, no bash needed), tool-call reliability fixes.
• 😅 Forked a popular router, then immediately wrote a comparison table roasting the original's Windows support. Gives full credit to upstream while explaining, in detail, why upstream is grumpy. Peak open-source energy.

Digitalizing sub-district (kelurahan) services in Simokerto, Surabaya. A full ecosystem: backend + 2 mobile apps + a web dashboard, complete with an ESP32 IoT siren.

• 😅 The citizen app is literally called "Lapor Maling" (Report a Thief) and has offline support — because catching thieves must keep working even when the signal drops. Also, the entire backend lives in one main.js file, and the README proudly admits it.

The official site for DPD NasDem Sidoarjo: public info + a multi-tier admin CMS with election analytics per candidate/dapil/district/polling station (TPS).

• Stack: Next.js 15 · TypeScript · Tailwind v4 · shadcn/ui · Supabase (Postgres + Auth + RLS)
• Highlights: 3 admin tiers, scheduled WhatsApp broadcasts, Row-Level Security.

Paste a channel URL → get a performance dashboard built on a custom momentum score (views reach, views/day, engagement, velocity, recency) with breakout/cooling labels + CSV export.

• Stack: Next.js 16 · React 19 · TypeScript · Tailwind 4 · YouTube Data API v3
• 😅 Built an entire YouTube analytics SaaS with zero charting libraries. Either deeply principled or a flex. The scoring formula is suspiciously well-calibrated for someone who "just" peeks at competitors.

A tool for psychologists: record a session → separate speakers (Psychologist vs Patient) → auto-generate SOAP clinical notes.

• Stack: Next.js · FastAPI · WhisperX (diarization) · LLM · wav2vec2 ID/Javanese/Sundanese model
• 😅 The repo is named "Speach-To-Speach" (permanent typo), but the product is genuinely useful. The typo is the personality.

😅 Net result: I support more exchanges than I have trading accounts. And yes, that's more MQL5 than the average trader has read of the docs.

😅 "Limit bandwidth without admin access" is a very polite way to describe what this does to your roommate's gaming session.

• 🤖 Manta-Hackaton-v1.0 "Arcalis" — A decentralized AI platform on Manta Network: quadratic-voting DAO, ZK privacy, routing across 6+ AI models. (Original)
• 🎫 ICP-BlockTix-Contract — On-chain event ticketing (Solidity, Truffle, OpenZeppelin). Named "ICP" but actually deployed on Ethereum testnets (Holesky/Bitfinity) — an identity crisis, now at peace.
• 🔗 d.a.t.a🍴 fork · mev-toolkit🍴 fork · web3-scripts

• 🚁 KRTI_Dirgasena_2025_VTOL — An autonomous hexacopter drone system for the FAIO 2025 competition: takeoff → navigate 12 checkpoints → object detection (YOLO) → pick up/drop objects with a magnet → auto-land. ROS 2 Humble + Python, with just as the task runner.
• 📓 A few Skripsi_* repos — Jupyter-based ML experiments (helping friends' research).
• 😅 Uses just (not Makefiles) to build robots — caring about Developer Experience even while flying drones.

• 🏫 Polishing JagaSekolah for LIDM (offline PWA + calibrating the scoring with a partner school)
• 💹 Quant research: combining ML + Smart Money Concepts for gold trading
• 🤖 AI-powered developer tooling (routers, security agents, MCP servers)
• 🧹 ...and one day, writing a README for my own portfolio repo 😌
