I help teams build and improve web products when the work calls for senior architecture judgment and hands-on implementation. Bring me in to assess an inherited application, plan a new product, or resolve problems across the frontend, APIs, and data layer. My stack includes Next.js, React, Node.js, PostgreSQL, and Firebase. You work directly with me on the technical decisions and delivery. How I can help • Architecture and codebase review: understand the current system, identify constraints and risks, and prioritize the work. • Full-stack implementation: develop agreed features, API integrations, authentication flows, and database-backed functionality. • Stabilization and modernization: diagnose root causes, improve maintainability, and plan practical changes to an existing product. • Technical handoff: document decisions, setup, and the next steps your team needs. We agree on scope and deliverables before implementation. Start with a focused technical review or discuss a defined development engagement. Consulting is $100/hour; project estimates depend on the codebase and requirements.
