Ported legacy Node.js API backend to Go; achieved 3× reduction in average latency and brought p99 response times under 50 ms. Led full MongoDB → PostgreSQL migration with seeding/migration scripts; evolved dedup to idempotent writes via ON CONFLICT DO NOTHING / DO UPDATE.

Adopted

TimescaleDB for rows updated every 60 s; added B-Tree and BRIN indexes — 80 % less disk I/O, 90 % faster reads.

Backend Engineer – Full-Time (2025-10 – Present)

• Ported legacy Node.js API backend to Go; achieved 3× reduction in average latency and brought p99 response times under 50 ms.
• Led full MongoDB → PostgreSQL migration with seeding/migration scripts; evolved dedup to idempotent writes via ON CONFLICT DO NOTHING / DO UPDATE.
• Adopted TimescaleDB for rows updated every 60 s; added B-Tree and BRIN indexes — 80 % less disk I/O, 90 % faster reads.
• Built dependency intelligence bot: scanned lockfiles against npm registry + OSV feeds, delivered severity-based Slack alerts with dedup and digest aggregation.
• Built vault activity bot: indexed onchain contract events, normalised into canonical schema, pushed real-time alerts via queue-driven pipeline.
• Architected event-driven pipeline: ingestion → normalisation → queue → rule engine → consumers; replay-safe, rate-limited, modular.
• Deployed production stack: Go binary in Docker behind Caddy on a single VPS (Hetzner), managed PostgreSQL, GitHub Actions CI/CD; graduated to Kubernetes only after splitting into multiple services.
• Isolated key management into a dedicated signer service backed by HSM; built RPC node failover with multi-provider rotation directly in the Go service layer.
• Built CI/CD security pipeline: npm audit + Semgrep + TruffleHog on every commit via GitHub Actions.
