Jul 2024 – PresentSoftware 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
—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.
—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.
—Bitcoin CoinJoin detection engine in Go that indexes the blockchain and detects Whirlpool, Wasabi, JoinMarket, and Stonewall patterns using structural heuristics backed by academic research. Stores results in PostgreSQL and provides a queryable REST API for forensics and adoption analysis.
—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.
