Hi, I'm Donnovan.
Systems & Infrastructure Engineer — architecting reliable, secure, and automated cloud platforms — most recently at AlphaSense and NASCAR.
About Me
Building secure, reliable
Building secure, reliable
cloud infrastructure.
I architect and secure cloud infrastructure on AWS. I build reliable, automated platforms using infrastructure-as-code (Terraform), enforce security guardrails (IAM/OAuth), and design high-throughput data pipelines (ETL/SQL). My focus is on the reliability, security, and observability of production systems — from CI/CD quality gates to Datadog-driven incident response.
Seven-plus years of experience across cloud infrastructure, DevSecOps, data engineering, and quality engineering — with the production instincts that Platform, Data, and Security roles require.
Cloud Infrastructure & Automation
AWS (Lambda, EKS, S3, RDS, SQS), Terraform, Kubernetes, serverless architectures, and infrastructure-as-code that scales under real load.
Security & DevSecOps
IAM least-privilege design, OAuth/OIDC (Auth0) integration, secrets management, dependency scanning, and code review enforcement for secure systems.
Data Engineering & ETL
PostgreSQL, MySQL, MongoDB, and Redis schema design, query optimization, high-throughput ETL pipelines, and data modeling for analytics platforms.
Quality Engineering & Observability
CI/CD quality gates, API contract validation (Postman/Newman), Datadog dashboards and alerting, SLO/SLI definition, and regression testing that keeps releases reliable.

My professional journey.
Senior Software Engineer / Development Manager
NASCAR
- Hardened and secured containerized workloads on Amazon EKS by implementing IAM least-privilege policies, managing secrets, and enforcing dependency scanning within GitHub Actions CI/CD pipelines.
- Designed and deployed a comprehensive observability stack (Datadog dashboards, distributed tracing, and SLO-based alerting), reducing MTTD by approximately 40% and providing on-call engineers with high-signal incident data for rapid resolution.
- Architected CI/CD quality gates and automated API contract validation (Postman/Newman) across the SDLC, creating a repeatable regression testing framework that standardized release verification and rollback procedures.
- Provisioned and managed multi-environment AWS infrastructure using Terraform (Lambda, SQS/SNS, RDS, IAM), ensuring environment parity and reliable test/prod consistency through infrastructure-as-code practices.
- Engineered high-throughput ETL pipelines in Java to parse and extract structured race data (driver stats, finishing positions, lap data) from PDFs into PostgreSQL, implementing schema optimization and query indexing to feed downstream APIs and analytics platforms.
- Architected a decoupled headless WordPress platform serving millions of monthly visitors, implementing full API contract validation and cross-device compatibility testing for reliable content delivery.
Senior Software Engineer
AlphaSense
- Designed and validated database schemas and pipeline architecture supporting high-throughput, low-latency query workloads over structured and unstructured financial data — including indexing correctness verification and performance regression testing.
- Architected API contracts for cross-content search with strict permissioning and data isolation; authored and executed integration tests verifying data boundary enforcement.
- Performed systematic Core Web Vitals audits and resolved frontend performance bottlenecks, documenting findings and verifying fixes through structured retesting.
Senior Software Engineer
PriceWeber
- Delivered custom backend and frontend implementations with full cross-device/cross-browser compatibility validation; performed technical audits across SEO, WCAG accessibility, and Core Web Vitals with prioritized remediation plans.
Software Engineer
Sagefrog Marketing Group
- Architected a decoupled WordPress + Vue.js headless platform with API-driven content delivery, consistently achieving 90+ Lighthouse performance scores through structured performance and quality auditing.
- Established coding standards and structured code review practices; mentored junior and mid-level developers on testing discipline, security best practices, and quality ownership.
