What I'm looking for

I want to build AI-powered products end-to-end—owning schemas, scalable APIs, and multi-tenant SaaS features. I’m excited by LLM integration (OpenAI/Gemini/LangChain, RAG) and teams that value shipping measurable improvements fast.

I’m a Full-stack developer with 1+ year building and maintaining AI-powered products in production. I focus on shipping features end-to-end, from schema design to deployment, with practical performance and reliability in mind.

At AST Consulting, I built multi-model LLM integration that generated SEO, AIO, and GEO-optimized articles across 15+ client properties. My PromotoAI content engine processes 500+ content generation requests daily, with bulk operations, approval workflows, and version history.

I also developed D2CBot using NestJS microservices and React.js dashboards for AI-driven product-description generation for Shopify D2C brands. By adding BullMQ job queues and Redis caching, I cut processing time under peak load by ~40%, and built multi-tenant RBAC and AI-assisted drafting in Odin CMS to reduce editorial turnaround by ~35%.

Beyond work, I’ve shipped projects like a YouTube summarization Chrome extension that uses Clerk and Stripe for independently monetized value. I’m energized by building scalable REST APIs, integrating LLMs (OpenAI/Gemini/LangChain, RAG), and improving real-world outcomes for users.
