- Led Product development with React, Node.js and Express, refactoring APIs for property management workflows, optimizing data models, and improving response times by 40%.
- Shifted the web client to AWS Amplify for CI/CD and global CDN delivery—single-command builds now auto-deploy in under 2 minutes, giving marketing 'instant' feature flags and cutting front-end release friction by 70%.
- Containerized the Node.js / Express API and deployed via AWS App Runner (apprunner.yaml), enabling fully managed autoscaling from 0 → 50 containers in peak rental-season traffic while holding p95 latency below 200 ms.
- Adopted MongoDB Atlas as the primary datastore—migrated legacy SQL tables to a document model that slashed duplicate lookups and trimmed API response payloads by 40%.

Selected Projects
- AI-Powered Event Ingestor, Designed and deployed a Django + Celery micro-service that ingests user-supplied event URLs, calls OpenAI via the Python Agent SDK to extract titles, dates, venues, and imagery, then auto-seeds a StreamChat conversation so users can review and publish in one click—cutting manual data entry time by >80%.
- Next.js 14 Global SEO Migration, Re-platformed a React Native/Expo app to Next.js 14 with file-system routing, ISR (5-min revalidation), and shadcn/ui. Built an automated static-generation pipeline that publishes fully indexed, SEO-optimized landing pages for every city on Earth (~150 k locales); kept TTFB < 100 ms and delivered a 20% surge in organic traffic within the first months.
- Red / Blue Team Cyber-Range Automation, Authored a full-spectrum adversary OP plan for the DoD Persistent Cyber Training Environment (PCTE) that emulates Volt Typhoon TTPs across initial access, persistence, lateral movement, and exfiltration. Built an IaC pipeline with Terraform + Ansible + DetectionLab to spin up identical sandboxes on both PCTE and a local ESXi detection-lab cluster, letting analysts rehearse scenarios offline before live range events. One-click deployments stand up multi-VM Windows Server 2019 and Linux nodes, pre-loaded with Sysmon, Winlogbeat, and ELK, cutting range prep time.
