Profile Description

AI Full Stack Engineer — I Build Apps That Think

Hi, I'm Leff with a specialization in building AI-powered web applications that actually work in production. I don't just integrate AI features; I architect them from the ground up. From RAG systems and autonomous AI agents to multi-agent orchestration and MCP integrations.

Currently working as a AI Full Stack Developer at a BPO tech company, I've shipped production apps with AI features including ChatPDF, ImageGen, VideoGen, and intelligent chatbots, with full ownership over performance, SEO, CI/CD pipelines, and cloud infrastructure on AWS and Google Cloud.

What sets me apart: I can take a product idea from wireframe to deployed, scalable application
frontend, backend, AI layer, database, and DevOps included. I've worked with cross-functional teams, managed CRM integrations (HubSpot, Brevo), tracked user behavior via Mixpanel, and built agentic workflows using tools like OpenCode, Claude Code, and Cursor.

If you're looking for someone who can build smart apps fast, communicate clearly, and own the full stack. Let's talk.
