About

Full stack developer with 3+ years in tech and hands-on experience shipping AI products that real customers actually use. I design and build the full architecture for SaaS platforms and AI agent systems as a solo developer, from system design through deployment, and I keep infrastructure lean so costs stay under control. Over the last 6 months I've also worked directly with small businesses and startups on growth, so I'm as comfortable talking to a client as I am writing the code.

I like owning a product end to end: the architecture, the AI behind it, and the business result it's supposed to deliver.

Experience

Solo Full Stack Developer & Business Growth Partner at FusionSync AI (2024-05 – Present)

Work as the sole developer designing and shipping production AI SaaS platforms end to end, owning every architecture decision, the build, and the deployment, with no team to fall back on.
Start every build with architecture and research first, choosing simple, low-cost infrastructure over unnecessary complexity so hosting and tooling costs stay down without cutting corners on quality.
Build agentic AI systems and conversational workflows that handle real customer interactions on their own, with a human handoff when needed. These run live in production, not as demos.
Build generative UI and AI-driven dashboards that adapt to the user and the business context instead of showing the same static screen to everyone.
Connect Instagram, WhatsApp, SMS, voice, and email into single cross-channel automation workflows, integrated with GoHighLevel and custom CRMs.
Implement authentication and multi-tenant architecture from scratch on every platform rather than relying on boilerplate or templates.
Work hands-on with OpenAI and other LLMs to build and tune agent behavior, not just wire up an API call. That means prompt design, workflow logic, and handling failure cases properly.
Also drive growth for the business itself: client communication, marketing, and lead generation for small businesses and startups, turning technical work into results clients can actually see.
