Hire
Backend architect & tech lead for systems that must hold.
I help teams design and ship NestJS/Node.js platforms — payments, multi-tenant SaaS, and event-driven backends — with measurable latency, uptime, and correctness outcomes.
Backend architecture
Service boundaries, API contracts, polyglot persistence, and evolution strategies that keep clients stable.
Tech lead delivery
Own critical paths end-to-end: design reviews, production readiness, observability, and calm incident response.
Fintech & payments
Idempotent money flows, reconciliation, policy/limits, and integrations where correctness is non-negotiable.
Multi-tenant & event-driven systems
Tenant isolation, Kafka/Event Hubs pipelines, Redis for cache and rate limits, throughput without leakage.
Engagements that fit
- • Freelance / contract backend architecture
- • Associate Tech Lead or staff-level delivery on a critical track
- • Short architecture spikes with clear recommendations
- • Remote-first, async-friendly collaboration
