Ihor Verkhohliad

Backend-leaning full-stack engineer with 9+ years shipping and operating production systems, including Web3 products that move real value. I care about “boring” fundamentals, correctness, performance, and operability because that’s what users actually feel.

Core strengths

• TypeScript/Node.js: secure APIs and services; async/streams/perf tuning; background jobs; caching/rate limiting; safe migrations
• PostgreSQL: schema design, indexing strategy, query optimization, transactional correctness
• Reliability/observability: structured logs, metrics/traces, dashboards/alerts, pragmatic runbooks (systems you can debug at 3am)
• Security-first: threat modeling, careful secrets/key handling, dependency hygiene, thorough automated tests
• Web3/EVM: RPC integrations, event ingestion/indexing, reconciliation pipelines, resilient value-moving flows
• Delivery/infra: Docker, CI/CD (GitHub Actions), and enough Kubernetes/cloud to deploy, scale, and keep services healthy

Frontend: comfortable in React + TypeScript (Next.js) I’ll jump in when needed.

Working style: small PRs, clean docs, direct communication, and strong ownership if I ship it, I support it, measure it, and keep improving it.
