Experience
Lead Performance & Systems Engineer
Designed a full-duplex WebSocket architecture that replaced HTTP polling for real-time dashboards.. Built an industrial Digital Twin platform ingesting high-frequency sensor telemetry for real-time structural monitoring of refinery equipment, from ingestion through the API layer to the operator UI.. Led the migration of legacy monoliths to cloud-native microservices on AWS, defining service boundaries, deployment flow and architectural trade-offs.. Created and maintained the main industrial web platform (Nuxt/Vue, Express/TypeScript, Sequelize/MySQL, AWS): ~2,000 commits, integration point for a ~14-person team, owner of the build and release cycle.. Built an offline-first desktop ecosystem with bidirectional cloud↔local sync (Python orchestrator, Node/TypeScript services, FastAPI, MariaDB, S3) so plant teams work with no internet and reconcile automatically.. Built a desktop app for coordinated control of networked industrial IoT hardware (Python, PyQt5, Socket.IO), designed to run unattended on unreliable networks.
Senior Software Engineer (Contract)
Built and containerized backend services with NestJS and Docker; set up CI/CD with GitLab CI, GitHub Actions and AWS CodePipeline (CodeCommit, CodeArtifact, CodeBuild, CodeDeploy).. Audited 4 production stacks and fixed 3 memory leaks and concurrency bottlenecks in point-cloud processing (up to 1.2M points).. Designed TCP socket and WebSocket services with custom file-transfer protocols for high-frequency environments.. Developed video stabilization engines (optical flow, matrix interpolation; Python, NumPy, SciPy, OpenCV) with 65–80% jitter reduction at 60 fps, HD to Full HD.. Presented audit findings and remediation standards to the client's engineering team and specified the changes they adopted.
