What I'm looking for

I’m looking to build early-stage SaaS MVPs and AI-driven backend services—shipping conversational automation, scalable REST APIs, and measurable product features with tight cross-functional iteration and real customer validation.

I’m a Senior Full-Stack Engineer with 9+ years of experience delivering early-stage SaaS products, AI-driven backend services, and scalable API platforms. I specialize in building lightweight MVP architectures—especially conversational automation workflows, real-time integrations, and data-driven product features—using Node.js, React, and modern cloud tooling.

At Stramik (2023–2026), I led backend delivery for an AI-powered customer support chatbot, connecting conversational flows to Shopify data endpoints for real-time order and catalog access. I designed escalation routing with Dialogflow and Twilio and added background processing for syncing conversation logs for later analysis. Earlier, as Founding Lead Engineer at ScanRev (2019–2022), I architected and launched a cloud-based document management SaaS using ASP.NET Core, MongoDB, and Elasticsearch, and I set up containerized deployment pipelines with Docker and GitHub Actions.
