About

I’m an AI and full-stack software engineer with 3+ years of experience building applications across fintech, loyalty, and financial data. I work on greenfield projects, taking products from requirements and system design through backend development, frontend implementation, and cloud deployment. At Loylty Rewardz, my work spans applied AI, backend services, and web applications. My AI experience includes model training and deployment with AWS SageMaker, large language models (LLMs), retrieval-augmented generation (RAG), and applications in customer profiling, personalization, and fraud analysis. I build backend services with Java, Spring Framework, Go and Python, alongside React and Next.js interfaces. My work also covers REST APIs, PostgreSQL, Redis, asynchronous messaging with Kafka and RabbitMQ, and containerized deployment using Docker and Kubernetes. Previously, I worked on a stealth startup developing financial-data pipelines and NLP workflows, including transformer encoder training, text chunking, and semantic retrieval. Areas in which my core expertise lie are: • Applied AI: Large Language Models (LLMs), retrieval-augmented generation (RAG), AI agents, Model Context Protocol (MCP), and tool integration. • Backend and full-stack engineering: Java, Spring Boot, Python, React, JavaScript, REST APIs, PostgreSQL, and Redis. • Cloud and reliability: AWS, Docker, Kubernetes, CI/CD, and application observability using tools like Grafana.
