I build live backend systems where correctness, reliability, and operational ownership matter.
Senior backend/platform engineer for trading, fintech, Web3, infra, and data-heavy products. I work close to production: live state, execution flows, runtime signals, incidents, and product feedback loops.
I can go full hero mode when production needs it, but I treat that pressure as signal: turn hard edges into better architecture, observability, rollout safety, and calmer operations.
Live systems
Production systems with real users, live state, operational constraints, failure modes, and incident feedback. I prefer systems that fail loudly and teach the next iteration.
Trading / Web3 depth
Execution flows, market data, deterministic risk boundaries, oracle-style integrations, and correctness-sensitive backend work where mistakes have a price.
AI-native delivery
Closed frontier AI for coding and strategy development; local open-model workflows where validation and execution-adjacent evaluation need controlled, repeatable behavior.
Proof under pressure
Selected systems that show the kind of ownership I bring: live money, high-concurrency state, operational surfaces, and feedback loops where reality gives fast answers.
Mercury: AI-native trading engine
Profitable, production-ready private trading engine in an unfamiliar, execution-sensitive domain with a blunt success metric: PnL. Multi-intent execution, deterministic risk controls, portfolio neutrality, and AI-assisted strategy iteration.

High-concurrency portfolio systems
Flagship backend for 10k+ concurrent users: per-minute portfolio recomputation against live market data, dual-state anti-cheat design, API contracts, and fast product delivery under funding pressure.
Bot fleets and telemetry
80 concurrent Hummingbot instances with Telegram control surfaces and acoustic telemetry for real-time operational awareness, parameter tuning, and market-regime learning.
Good fit
- Trading, fintech, Web3, infra, or data-heavy product work.
- Backend/platform problems where correctness and production ownership matter.
- Teams that value clear constraints, fast feedback, and operational reality.
- Remote-first contract / B2B, or serious full-time startup roles with real authority.

Hiring for a serious backend/platform problem?
Send the context: what you are building, where the system hurts, what must not break, and what success should look like in production.
Best inbound path: [email protected]. Include the problem, timeline, expected ownership, and whether this is contract, B2B, or full-time. LinkedIn / Wellfound under Max Kaido are useful for background checks.
