Senior / Lead Web3 QA & SDET (Telegram Mini Apps, TON / EVM, Python)

I’ve been in software quality assurance for 5 years with 4 years of dedicated test automation in Python, specializing in high-concurrency Web3 platforms and Telegram Mini Apps (TMA / TON).

Over the past year, I served as the sole Lead QA & SDET for a viral Telegram Tap-to-Earn mini-app (TON ecosystem, comparable to Hamster Kombat / Notcoin) scaling from MVP to viral growth and on-chain token launch:

  • Anti-Cheat & Concurrency Security: Eliminated critical race condition bugs (preventing game balance double-spending) via distributed Redis locks (Redlock) and row-level PostgreSQL locking; validated backend HMAC-SHA256 initData signatures and Sybil defense against bot farms.
  • On-Chain & Smart Contracts: Tested TON Connect v2 wallet integrations (Tonkeeper, Telegram Wallet), Jetton (TEP-74) smart contracts, pre-market NFT vouchers, Merkle airdrop claims, and mandatory CEX Memo/Tag validations (preventing permanent fund loss).
  • Scale & Stress Testing: Ran high-concurrency load tests up to 50,000+ RPS and WebSocket connection bursts using Locust & k6.

In enterprise software platforms, I also architected an end-to-end CI/CD test automation framework (1,288 automated tests: Playwright + requests) that slashed manual regression from 1 full week down to 4 hours.

Now, I'm looking for a full-time or contract Senior / Lead Web3 QA / SDET role where I can ensure bulletproof reliability, protect game economies from exploits, and build rock-solid automation from day one.
