About

Senior software engineering, cloud architecture, and applied AI.

Leo Pathu

I help startups and enterprises design, build, and scale production-grade software with cloud-native architecture, AI-enabled workflows, and practical engineering choices.

Over the years I have worked across healthcare, research, non-profits, SaaS, and internal platforms, building systems that need to be fast, maintainable, and dependable in production. That includes AWS platforms, serverless and container-based deployments, RAG-style AI systems, and full-stack web applications.

I tend to prefer simple systems over fashionable ones. The goal is usually the same: make good technical decisions early, reduce avoidable complexity, and keep teams moving.

Cloud Architecture

Secure, scalable infrastructure across compute, storage, networking, data, and deployment workflows.

AI Integration

RAG pipelines, API integrations, internal AI tooling, and practical model-backed product features.

Full-Stack Delivery

Laravel, React, Node.js, Drupal, and Python systems built with maintainability and long-term ownership in mind.

Technical Advisory

Architecture reviews, roadmap guidance, delivery strategy, and CTO-level support for growing teams.

My projects have included research platforms for scientific collaboration, serverless workflows for non-profit operations, patient monitoring systems, internal automation tools, and AI-backed applications built on private business data.
