I build SaaS products, full-stack web applications, and backend systems with Next.js, Node.js, TypeScript, JavaScript, and APIs. I’m particularly useful when an application needs more than a frontend users, business logic, databases, payments, third-party APIs, webhooks, and other systems all need to work together reliably. My core work includes: • Next.js and TypeScript web applications • Node.js backend development and REST APIs • Full-stack JavaScript/TypeScript development • SaaS applications and database-driven systems • Third-party API integrations and business-system connectivity • Dashboards, admin panels, and user portals • Payment and business-system integrations • Existing application fixes, improvements, and feature development • Python backend and API development • AI/API integrations where they genuinely fit the product My approach is straightforward: understand the workflow first, define the right architecture, and build a maintainable solution rather than adding fragile workarounds. I care about clean code, reliable integrations, sensible database design, performance, scalability, and clear communication throughout the project. I’ve earned $90K+ on Upwork, have 299 feedback entries, and hold Top Rated status. My Upwork work spans custom web applications, SaaS products, APIs, integrations, business systems, and ongoing product development. If you’re building a new application, extending an existing SaaS product, or dealing with an API or integration problem, send me the requirements and I’ll outline the technical approach.
