What I'm looking for

I’m looking for roles where I can build full-stack products (APIs, dashboards, authentication) and ship AI-enabled, data-driven solutions—especially WebGIS and geospatial intelligence—within an agile team that values documentation, security, and continuous learning.

I’m a versatile Full Stack Web Developer and Machine Learning/AI Engineer who builds responsive web applications, RESTful/GraphQL APIs, authentication-secured services, and data-driven dashboards. I combine front-end development with React, Vue.js and Angular, and back-end engineering with Node.js, Laravel, Python (Django/Flask), Spring Boot and .NET.

I also design and deliver AI/ML training as an AI Engineer and Trainer, creating practical labs, workshops, reusable technical materials, and ML workflows from problem framing to evaluation and reporting. Alongside this, I develop geospatial and WebGIS prototypes—using GIS tools, geospatial libraries, and automation—to turn raw data into actionable insights.
