Summary

Software engineer with 20+ years of experience building and operating distributed systems in financial and blockchain environments. Designs and delivers production systems under real-world constraints, including high availability, fault tolerance, and regulatory requirements. Strong focus on event-driven architectures, infrastructure control planes, and large-scale data systems. Proven ownership of systems spanning backend services, infrastructure, and data pipelines.

Experience

Validation Cloud — Senior Backend Engineer

2022 – Present
  • Built a production Ethereum Staking-as-a-Service platform automating validator lifecycle end-to-end, including deposit handling, provisioning, monitoring, rewards indexing, and MEV integration
  • Extended staking infrastructure to support EigenLayer restaking and SSV-based distributed validators, increasing system flexibility and fault tolerance
  • Designed and implemented a real-time billing and usage metering system for RPC-as-a-Service, including compute-unit accounting per method, free-tier enforcement, invoicing, and payment retry flows
  • Developed wallet intelligence datasets powering blockchain analytics, including attribution of funding sources and geographic inference from on-chain activity
  • Implemented OFAC compliance screening at RPC transaction level, enforcing regulatory constraints in production infrastructure

Voyager — Software Engineer / Tech Lead

2022
  • Led extraction of accounting domain from a Node.js monolith into an event-driven Go microservice, isolating financial logic and introducing Kafka-based ingestion
  • Re-architected transaction processing to an event-driven model with per-customer ordering guarantees via partitioning
  • Introduced feature-flag-driven deployment workflows, enabling controlled rollouts and rapid rollback in a high-risk financial system

Infoblox — Staff Software Engineer

2019 – 2022
  • Designed and built a control-plane-driven configuration system for DNS (BIND) and DHCP (Kea) infrastructure, translating user-defined intent into executable configurations
  • Implemented targeted configuration rollout, applying changes only to affected nodes and reducing unnecessary reloads and service disruption
  • Built configuration versioning and forward-compatibility mechanisms, enabling seamless infrastructure upgrades without downtime
  • Developed backend services in Go on Kubernetes supporting hybrid cloud and on-prem DDI deployments
  • Resolved production issues in distributed systems handling configuration propagation and state synchronization across infrastructure

Trax Image Recognition — Backend Team Lead

2015 – 2019
  • Architected and led development of a distributed image processing pipeline handling ingestion, recognition, stitching, deduplication, human review, and reporting
  • Designed dependency-aware workflow execution system ensuring correct sequencing of pipeline stages
  • Implemented coordination mechanisms using database-level atomic primitives to guarantee correctness under concurrency
  • Built IoT-based image capture system with Raspberry Pi devices and in-store cameras, replacing manual data collection
  • Designed edge-to-cloud data flow handling unreliable connectivity, device failures, and large-scale ingestion
  • Led backend team across cloud and edge systems in a high-throughput production environment

Whitebay Technologies — Software Engineer

2012 – 2015
  • Built risk management and monitoring systems for high-frequency trading infrastructure, including trade recording and enforcement of loss limits
  • Contributed to exchange-adjacent trading systems with performance monitoring and safeguards
  • Implemented market-aware constraints using external data sources (e.g., dividend event handling)
  • Developed distributed compute systems for research and trading strategy analysis
