Summary

I lead backend architecture for high-performance services: clear boundaries, observable systems, and decisions that hold up when traffic and teams grow.

Recent work centers on Web3 trading and blockchain products — TRON energy markets, TON trading, metaverse backends. I also run a small AI lab (blog + tooling) as craft proof, not the headline.

Experience

  1. Back End Leader / Silotech

    Nov 2022 — Present

    • Buyers needed TRON energy without running stake — built marketplace matching ~4/s · ~50ms; ~1k orders/day · ~60k TRX/day; peak TVL ~$45M.
    • Telegram trading confirmations lagged ~60s — cut confirm path to ~10s; sustained market-data ~40 req/s (peak ~100).
    • Growing backend team needed clear ownership — lead 4 · mentor 1; 99.9% SLA · ~1 serious incident/year.
  2. Back-end Developer Leader / The Parallel — An Infinite Metaverse

    Oct 2021 — Nov 2022

    • Craftable character space grew 20³→100³ — kept NFT uniqueness compare ≤~2 min at scale.
    • Metaverse sessions were write-heavy — sustained ~20 concurrent / peak ~100 on game relay.
    • Backend for ~6-person team — cube→NFT pipeline, game relay, anti-cheat/reward bots.
  3. Back End Developer / Silotech

    Nov 2020 — Oct 2021

    • History queries timed out on full scan — index + light cache ~1–2s → ~50–100ms (stale ~2–3s OK).
    • Shipped Node.js APIs end to end — owned design, implementation, and production behavior.
    • Ran production ops for every service I delivered — on-call and fixes included.
