Full-Stack SaaS Developer | Next.js, NestJS, Stripe & APIs
I build SaaS products and complex web applications from scratch — from architecture and backend development to modern interfaces, integrations, and production deployment. I'm a Full-Stack Developer experienced with React, Next.js, TypeScript, Node.js, NestJS, and PHP. I focus on building reliable, maintainable applications that solve real business problems. WHAT I CAN HELP YOU WITH • SaaS & MVP Development — Complete web applications, from idea to production. • Full-Stack Development — Modern React/Next.js interfaces with scalable backend architecture. • Backend & APIs — REST APIs, authentication, database design, and third-party integrations. • Stripe & Payments — Subscription billing, webhooks, payment workflows, and automation. • Dashboards & Business Tools — Admin panels, CRMs, analytics, and internal platforms. • Existing Applications — Debugging, refactoring, performance optimization, and new features. • DevOps & Deployment — Docker, CI/CD, Redis, Nginx, and Linux infrastructure. REAL PRODUCT EXPERIENCE I'm the founder and developer of Lirova, a SaaS platform built to help subscription businesses manage failed Stripe payments. I designed and developed the application independently, including its frontend, backend, Stripe Connect integration, payment workflows, background job processing, and deployment. Building my own product has given me practical experience making technical decisions, solving complex problems, and taking responsibility for an entire application.
