Senior Software Engineer – Sovrn Holdings
2018 – 2025
Cost Optimization & Performance Engineering (2024–2025)
- Architected and executed ARM Graviton cross-compilation migration reducing compute costs by $375k/month ($4.5M/year) for ad exchange infrastructure processing 350 billion transactions/day; optimized for m7g instances vs. requiring latest-generation hardware
- Optimized Vert.x/Netty network stack enabling native transport and pooled buffer allocation, improving request latency by 50–120ms at scale; enforced <60-second startup constraint to meet deployment pipeline requirements
- Reduced local development environment footprint to 3GB for main application (6GB full stack including Redpanda, OTEL collector, Zipkin) through ONNX low-memory mode and JVM native memory tuning, enabling development on 16GB workstations
Observability & Platform Engineering (2024)
- Architected company-wide observability platform from scratch using Rust (self-taught), serving CTO, 8 engineering teams, and on-call engineers with 100+ custom metrics from GitHub, Jira, VictorOps, Tanium, AWS, and SonarQube
- Deployed on single EC2 instance (<$50/month) with daily automated security rebuilds; achieved 1+ year of zero-maintenance production uptime with no incidents post-handoff through robust error handling and self-healing design
- Integrated Tanium security auditing generating real-time vulnerability dashboards (CVEs, outdated libraries) across EC2/RDS infrastructure with automated alerting for critical compliance issues
- Designed metric aggregation and cardinality strategy balancing API rate limits, Datadog costs, and visualization requirements (rolling vs. sprint-boundary averages, time-series vs. scalar displays)
Ad Exchange Development & Integration (2025)
- Contributed to 5-engineer team building Java/Vert.x ad exchange processing 350 billion transactions/day; led Java 24→25 migration with comprehensive documentation and build tooling updates (mvnw/mvnd)
- Designed OpenTelemetry trace pipeline with intelligent filtering, preserving critical debugging tags for source-level traceability while reducing Datadog ingestion costs; built executive Grafana dashboard integrating metrics across multiple SSPs/DSPs
- Implemented OpenRTB-compliant deal handling (Sigma deals, programmatic guaranteed) with comprehensive E2E test suite enabling test-driven development; added gzip compression for SSP/DSP communications reducing network egress costs
- Architected AI-accelerated development workflow using Cursor+Claude with MCP server integrations (Jira/Confluence), enabling automated code reviews, branch switching, and development task automation
- Emergency-rescued orphaned Salesforce integration post-RIF (Summer 2024), reverse-engineered AWS S3→MuleSoft→Salesforce pipeline enabling near-real-time sales performance data for account executives
Infrastructure & Automation (2018–2023)
- Implemented ephemeral Docker testing environment enabling local simulation of entire tech stack, expediting datacenter decommissioning and parallelizing dev-test cycles across engineering teams
- Replaced commercial performance testing software with custom scalable EKS solution, measurably reducing infrastructure spend while improving test coverage
- Architected live upgrade plan for global Aerospike infrastructure avoiding downtime and revenue loss, automating deployment via Ansible/Molecule; designed Kafka migration from legacy to 2.3 with compression optimization for throughput
- Deployed SonarQube across organization for automated code coverage reporting; streamlined engineer onboarding to expedite productivity and standardize practices across teams
