About

I’m a problem solver first, engineer second. What drives me is frustration with scams, hype, and wasted tech, so I use software engineering as a toolkit to solve real-world problems and build trust. I thrive on adaptability. From Angular + TypeScript in enterprise apps, to Next.js + React for SaaS, to Rust + Docker backends, to AI-powered Telegram bots with LangChain, I learn fast, adapt fast, and build what the problem demands. Beyond coding, I’m developing the harder skills that truly make an engineer valuable: - System & Architecture Design – how parts fit together to scale securely. - Communication with Smart Teams – turning complex ideas into clear action. - Understanding User Needs & Flows – designing from first principles, not assumptions. - Attention to Detail – spotting what others miss without losing sight of the bigger picture. For me, tech is never the goal.. solving the problem is.

Crypto red flag scanner

Founding Member

May 2025 – Oct 2025 · 5 mos · Singapore · Remote

Helping crypto investors, analysts, and VCs detect scams and weak projects in under 3 minutes — without needing to dig into GitHub, tokenomics, or Telegram noise.
Built and launched a real-time crypto red flag scanner, with:
Rust (Axum) backend
Docker + Makefile automation
Deployed to Fly.io (public backend)
Next.js frontend (App Router)
Live API integration (e.g. CoinGecko)
Monorepo architecture with CI-friendly structure
Early steps toward Web3 trust scoring
What the scanner does:
Flags projects with fake teams, vague tokenomics, or missing GitHub/audits
Exposes hype-driven tokens with no real utility
Cuts DYOR time from 10+ hours → under 3 minutes
Public tool available for investors, analysts, and builders
Milestones:
Deployed backend on Fly.io using Docker + Rust
Built + shipped MVP with token risk checks for XRP, SUI, Worldcoin
Public repo: monorepo structure with GitHub link + README
Real-time supply API integrated from scratch
Added /ping, /health, /version routes with REST
Resolved CORS & connected via .env
Preparing for live user testing + roadmap toward institutional scoring
Call to action:
If you’re a crypto analyst, investor, founder, or Web3 researcher — let’s connect.
I’m open to:
Early testers
Critical feedback
Collaborations on AI x Blockchain x Risk Analysis
Serious job opportunities in Rust / Crypto / AI infrastructure roles
