Software Engineer → Sr. Software Engineer

Promoted: Jan 2025
  • Deployed and maintained 10+ blockchain full nodes across UTXO and account-based chains for analytics, monitoring, ingestion, and large-scale backend processing workloads.
  • Designed backend systems for multi-tenant enterprise platforms, including org-level access control, RBAC, subscription management, feature isolation, and scalable user hierarchy models.
  • Built in-house blockchain indexers and high-throughput ingestion pipelines for Dogecoin and BCH with Neo4j integration, reducing dependency on third-party providers, lowering operational costs, and improving API response time by ~40%.
  • Optimized internal dark-web crawling and search systems by rewriting critical services from Python to Go, improving indexing pipelines, and integrating automated OSINT enrichment workflows, reducing execution time from ~45 minutes to ~5 minutes, cutting fetch latency by ~75%, and reducing manual analyst effort by ~60%.
  • Built end-to-end observability and monitoring stack using Prometheus, Grafana, and Uptime Kuma, reducing incident detection time by ~70% and improving service reliability across production systems.
  • Introduced Redis-based caching and optimization layers across backend services to improve response time, reduce database load, and stabilize performance under high concurrency.
  • Led on-prem to cloud migration on AWS and GCP with near-zero downtime, improving deployment reliability, infrastructure scalability, and operational monitoring.
  • Managed backend infrastructure across Linux production environments, including process supervision, service automation, backup workflows, deployment pipelines, and system performance tuning.

Open Source Projects

Bitcoin Blockchain Indexer

Go-based blockchain indexer with batch ingestion, UTXO parsing, resumable sync, and PostgreSQL storage for large-scale blockchain data processing. Built custom backfill and checkpointing mechanisms for reliable sync recovery, optimized bulk ingestion pipelines for high-throughput indexing, and designed schema structures for efficient transaction and address-level querying.

Traffic-Monitor

Real-time network traffic monitoring system in Go using libpcap/gopacket with GeoIP and ASN enrichment, Prometheus metrics, and Grafana dashboards. Added support for PROXY protocol based real-IP extraction behind load balancers, concurrent packet processing pipelines, and low-overhead monitoring for high-volume traffic environments.

Terminal-Chat

Terminal-based real-time chat system in Go with Telnet and HTTP support, PostgreSQL storage, Redis pub/sub messaging, AES-256-GCM encryption, and Tailscale VPN integration. Built concurrent session handling, terminal UI rendering, secure authentication flows, and distributed messaging support for low-latency communication across multiple clients.
