Golang Developer

Led deployment and maintenance of 10+ blockchain full nodes (UTXO and account-based) to support internal analytics, monitoring, and forensic workloads, improving data freshness and system reliability. Migrated the access-control system from a user-level hierarchy to an organization-level multi-tenant model with subscription tiers and feature-based permissions, enabling onboarding of enterprise and law-enforcement clients. Implemented end-to-end observability and alerting using Prometheus, Grafana, and Uptime Kuma, reducing mean time to detect (MTTD) incidents by 70% and improving system uptime. Optimized the internal dark-web intelligence engine, improving live result fetch latency by 75% and increasing signal accuracy through better indexing and filtering logic. Introduced multi-layer caching across backend microservices (Redis + in-memory), reducing redundant computation and cutting average API response time by 40% under high concurrency. Built UTXO blockchain indexers for Dogecoin and Bitcoin Cash (BCH) with full data ingestion into Neo4j, eliminating dependency on third-party APIs and enabling complete on-chain data availability for faster analytics and querying. Standardized infrastructure setup and recovery processes for blockchain nodes and backend services, improving reliability and consistency during deployments.
