Experience

Autonomous AI Document Processing & RAG Pipeline

Architected and implemented an autonomous AI workflow for enterprise document processing, utilizing LangGraph to manage complex, cyclic agentic behaviors. I pioneered the deployment of model context protocol (MCP) servers, standardizing the context exchange between LLMs and internal data tools to ensure seamless interoperability.

Key contributions included designing scalable retrieval-augmented generation (RAG) pipelines to extract and structure complex data from unstructured financial and legal documents with high precision. I also engineered high-performance, asynchronous REST APIs using FastAPI to expose these agentic capabilities to front-end applications, significantly reducing manual processing time and increasing data accuracy.

AI Transformation of Business Management Ecosystem

Led the strategic integration of Generative AI into a core business management platform, transforming a traditional .NET architecture into a hybrid AI-driven ecosystem. I developed a proprietary Text-to-SQL solution using LangChain, empowering non-technical users to query complex databases using natural language.

Additionally, I deployed intelligent customer support agents that automated routine inquiries, which drastically reduced ticket resolution time and operational overhead. To support these new capabilities, I modernized the front-end experience by re-architecting legacy components into reactive Vue interfaces, ensuring a seamless and responsive user experience.

Genius Loyalty Engine Migration & Streaming Architecture

Modernized the core Genius loyalty program engine by migrating legacy Perl monoliths to scalable, high-performance Java/Spring microservices. This critical system required handling millions of active daily users without downtime.

I engineered a real-time event streaming architecture using Apache Kafka and AWS, replacing legacy batch-based user promotion workflows with low-latency, event-driven solutions. I collaborated closely with data scientists and product managers to deploy complex business rules into production, ensuring high availability and seamless integration with the broader Booking.com ecosystem.

Scalable Back-end Architecture for Microsoft Teams & Skype

Developed and optimized mission-critical back-end services for Microsoft Teams and Skype, engineering solutions capable of handling millions of concurrent requests per minute. My focus was on ensuring high availability and low latency for global communication infrastructure.

I led the strategic migration of several on-premise legacy services to Azure Kubernetes Service (AKS), which modernized the deployment pipeline and significantly reduced operational infrastructure costs. Additionally, I enhanced a widely adopted service-to-service (S2S) authentication library used across multiple internal teams, improving security compliance and reducing token validation latency.
