Senior Software Engineer & Systems Architect with 18+ years building large-scale automation, distributed systems, and AI/ops tooling. Led Rackspace’s automation platform from legacy orchestration to a resilient, low-latency event engine processing 2M+ events/week. Drove multi‑year cost takeout ($500k+ annual) and latency reductions (10×) through pragmatic redesigns (Cassandra/ScyllaDB, Redis, Linux consolidation). Hands-on across Python, Go, Java/C#, and Rust (new stack for high‑throughput services). Calm under pressure; opinionated about reliability, observability, and operability.

• Architectures: Event-driven systems, stream processing, distributed job orchestration, multi-tenant workflow engines, REST/gRPC services
• Languages: Rust, Python, Go, Java, C#, TypeScript/Node, Groovy, Scala, C/C++
• Data & Messaging: ScyllaDB, Apache Cassandra, Redis (+Sentinel), PostgreSQL/MySQL, MS SQL Server, ActiveMQ, Kafka (lightweight usage), S3 (object storage)
• Infra & Ops: Linux (RHEL/CentOS, Ubuntu), Docker, SaltStack, CI/CD, GitHub Actions, observability (Grafana, Loki/Promtail, Prometheus), ServiceNow
• Cloud: AWS (EC2, S3, EventBridge/SQS patterns), GCP (Firebase), Rackspace
• Practices: SRE, performance tuning, schema design, compliance & audits (PCI), incident response, cost optimization, stakeholder communication

Senior Software Engineer / Systems Architect

2021–Present

• Lead engineer for Rackspace Business Automation (RBA)—mission-critical workflow platform handling 2M+ events/week, ~40 actions per event; improved end‑to‑end latency, stability, and debuggability.
• Database modernization & performance: Tuned hot paths, redesigned tables/indexes, and implemented ScyllaDB improvements; reduced p95 query latency ~10× (≈100ms → ≈10ms) and increased DB uptime 95% → 98%+.
• Reliability engineering: Introduced Redis Sentinel replication, hardened SaltStack-based fleet automation, and added proactive anomaly detection hooks for high-signal alerts.
• Observability: Standardized metrics/logs to Grafana/Loki; added run-history tracing and device‑level drill‑downs; cut mean time to diagnose (MTTD) for noisy workflows.
• Security & compliance: Led portions of PCI and ad‑hoc audit responses; automated evidence gathering and patch orchestration for Linux/Windows estates.
• Developer experience: Authored internal tools to bootstrap servers and repeatable environments; mentored devs on Rust adoption for low-latency services.

Enterprise Architect (Automation Pillar)

2019–2021

• Owned strategy and execution for automation architecture; partnered with Enterprise Architecture group to implement business value modeling and process improvements.
• Cost takeout: Migrated NoSQL stack from DataStax Enterprise to ScyllaDB → $385k/yr saved; consolidated OS from Windows Server to CentOS → $102k/yr saved.
• Delivered measurable platform outcomes: latency ~10× better, DB uptime +3pp, improved resiliency and operability across teams.

Software Developer IV

2014–2019

• Led RBA enhancements to scale from hundreds of thousands to millions of weekly events; maintained strict SLAs for ticketing and device orchestration.
• Drove cross‑company Moogsoft correlation rollout, cutting non‑value‑add alerts 85% → 95% and freeing operators for higher‑impact work.

Software Developer III

2011–2014

• Replaced BMC Atrium Orchestrator (legacy) → custom solution; $500k/yr savings.
• Migrated from MS SQL Server → Apache Cassandra; $100k/yr savings; enabled at‑scale write throughput.
• Built secure remote execution for device fleet (kernel/security patches, scripted maintenance) to reduce manual toil.

Software Developer II

2009–2011

• Early automation initiative: ticketing from monitoring events at ~100k events/week; integrated SOAP/DB systems; managed RealOps release processes.

Monitoring Administrator I

2007–2009

• Monitored global customer infrastructure; mentored admins; co‑designed process improvements that fed into the later automation program.

• Architect (Rackspace internal): Portal for automated server builds, hardening, and production cutovers with deep integration to the automation stack.
• ScyllaDB-based Search API: REST abstraction for trigram/exact‑match queries with dynamic filters; designed for .NET consumers; Rust service layer with env‑var config and Docker packaging.
• SentinelEdge: Prototype Rust inference engine (agent-core) + Python model-lab for anomaly detection on infra events; streams ScyllaDB CDC; real‑time alerting.
• SRE Sentinel (hackathon): Offline, privacy‑first SRE copilot combining local LLMs, CLI tooling, and a minimal web UI for diagnostics.
• Arc Reactor Notifier (personal): Raspberry Pi Pico W + NeoPixel ring; idle pulse & colored alerts mapped to custom event types.
