About Sam

I’m a Software Engineer focused on full-stack web platforms, geospatial/GIS applications, data-heavy workflows, and cloud-based internal tools.

My work spans backend architecture, frontend development, spatial data systems, PostgreSQL/PostGIS, Docker deployments, CI/CD pipelines, and production troubleshooting. I enjoy building practical systems that help teams manage complex data, automate workflows, and improve delivery without adding unnecessary complexity.

Beyond implementation, I’m involved in technical planning, architecture decisions, delivery coordination, and helping teams move from requirements to working software. I’m comfortable working across product, design, infrastructure, and operations, translating business needs into pragmatic technical solutions.

Recently, I have been applying AI-assisted engineering workflows to real software projects, including LLMs and agent-based systems for planning, implementation, testing, code review, documentation, and human-in-the-loop validation. My focus is using AI in a controlled way to improve clarity, quality, test coverage, and maintainability.

Core areas include full-stack development, SaaS and internal platforms, GIS applications, spatial data workflows, REST APIs, system integrations, PostgreSQL/PostGIS optimization, Docker-based deployments, CI/CD, production debugging, technical planning, and Agile delivery using Scrum, Kanban, TDD, and BDD.

Technical stack includes PHP, JavaScript, TypeScript, Python, SQL, Laravel, Django, GeoDjango, Vue.js, Angular, PostgreSQL/PostGIS, GeoServer, OpenLayers, Leaflet, Docker, Jenkins, GitLab CI/CD, Linux, WordPress, and automated testing tools.
