What I'm looking for

I want to build scalable full-stack products where I can deliver React/Next.js + Node/Nest.js features, real-time experiences, and reliable integrations (APIs, messaging, AI). I value agile teams, clear communication, and measurable impact.

I’m a Full Stack Developer with 5+ years of experience building full-stack web applications. I focus on scalable, high-performance, user-centric solutions using React.js, Next.js, Node.js, Nest.js, and MongoDB.

In recent work, I developed and integrated WhatsApp, Bitrix24, and VAPI workflows, and implemented Azure OpenAI services for AI-driven responses and automation. I also built backend APIs for multi-platform integration and added real-time chat and notification features using WebSockets.

At Blackhawk DM, I led building a dynamic website builder with a MERN stack and React-based templates (10+), and designed microservices architecture with NestJS and TypeScript. I built and maintained GraphQL APIs, managed RabbitMQ-based inter-service communication, and delivered real-time live updates and chat.

Earlier, at Xloop Digital Services, I built React/TypeScript experiences like a timeline chart capable of rendering 100K+ events fast, and I led full-stack development of an ATS system with Outlook integration. I also value teamwork and delivery—using Agile & Scrum, CI/CD workflows, and strong error handling, logging, and monitoring to keep systems reliable.
