Fullstack developer with 6+ years of experience building backend systems,
integrations, and automation tools end-to-end — from database design to
production deployment.

Core stack: Node.js, TypeScript, NestJS, React, Python, PostgreSQL,
MongoDB. I've built ERP systems for manufacturing companies, loyalty
platforms with POS integrations, and voice AI assistants (speech-to-text/
text-to-speech + LLM) for customer service automation.

Web3-specific experience: manually implemented the TonConnect protocol,
including bridge message decryption via NaCl — not just using an SDK, but
reverse-engineering the protocol itself. Built browser-automation clients
for Telegram Mini Apps (Playwright/Patchright) with network traffic
interception and wallet integrations (TON, Solana). Comfortable working
directly with blockchain APIs, wallet connect flows, and on-chain data.

Also do independent security research (mobile app reverse engineering
with Ghidra/Frida, web app vulnerability analysis) as an ongoing interest.

Looking for backend development, automation, and Web3 integration work —
happy to discuss project scope and timeline before committing.
