About

Senior Full Stack Engineer with 6+ years of experience building scalable SaaS and enterprise-grade systems across frontend and backend layers.I specialize in React and Angular-based frontend architectures combined with Node.js backend services, designing secure REST APIs, authentication systems, and distributed applications deployed on AWS.Currently, I work on an AI-driven consumer protection platform where I integrate LLM APIs for structured contract analysis, streaming responses, and secure AI processing in production environments.Previously, I contributed to enterprise network automation platforms, modernizing AngularJS systems, implementing React-based modules, and building scalable backend services for secure device provisioning.My focus areas include:• React & modern TypeScript architecture• Node.js API design and RBAC systems• AI / LLM integration in production• Cloud-native deployments on AWS• Performance optimization and clean architectureI enjoy working in product-focused teams that value clean code, system design thinking, and long-term maintainability.
