What I'm looking for

I’m looking to build and ship full-stack products end-to-end—especially AI-powered SaaS and automation—where I can own architecture, make smart trade-offs, and deliver reliable production systems with measurable business impact.

I’m a full-stack engineer and founder with 2.5+ years of experience shipping production systems and AI-powered workflows end-to-end. I use AI effectively, understand its limitations, and I know when manual engineering delivers better precision.

I’ve shipped 15+ full-stack applications, building scalable frontends, APIs, and production systems. I’ve also owned operations and planning for 3+ years—making trade-offs and meeting business goals while keeping execution tight.

Most recently, I architected a multi-tenant AISaaS with Next.js, React, Node.js, and MongoDB, including custom domains, tenant isolation, automated SSL provisioning, and secure ownership validation. I built an AI orchestration pipeline with OpenAI GPT-4, Google Places/Search APIs, and web scraping to analyze businesses, generate structured content, inject SEO metadata, and deploy complete websites in under 30 seconds.

I also built resilient automation systems—real-time visual CMS workflows, distributed job orchestration with concurrency control, safer long-running scraping, and high-volume email/SMS campaigns with scheduling, rate limiting, A/B testing, and analytics. Earlier, I delivered a production-grade storytelling React platform for the US Women’s National Soccer Team partners and led operational performance improvements as a Department Manager, including increasing profitability by over 50% in the first quarter.
