I’m a software developer with over 4 years of experience, specialized in Bubble.io, combining no-code/low-code development with a strong background in traditional web technologies and modern architectures. I have experience working with the MERN stack (MongoDB, Express, React, Node.js), Python, and building hybrid solutions where Bubble connects with external services to create scalable, production-ready applications. I specialize in: ✅ SaaS, CRM, dashboards, marketplaces & mobile apps ✅ Bubble database architecture & workflow optimization ✅ Process automation using n8n, webhooks & APIs ✅ AI integrations (OpenAI, Claude, custom AI assistants, RAG systems, embeddings, etc.) ✅ AI-powered business automations & agents ✅ Third-party API integrations (Stripe, WhatsApp, CRMs, marketing tools) ✅ Performance optimization & scalability for large apps Over the last year and a half, I worked on a large-scale project, coordinating tasks using tracking tools, contributing to technical decisions, optimizing workflows and handling complex databases in both development and production environments. I combine the speed of no-code with advanced technical implementations to deliver scalable, intelligent and automation-driven products. I’m constantly learning about AI applied to digital products, automation and emerging technologies, with a strong focus on delivering high-quality, future-proof solutions. If you’re looking for someone who understands both business and technology, and can help you scale your product with smart, AI-driven solutions, I’d be glad to collaborate.

For the last 2 years I've been involved in projects using ASP.Net Web API, Sql Server, and other Microsoft technologies working with frontend developers. to achieve a fluid web application using REST.
