• Business Continuity Plan

Developed a cloud-based automation tool that processes Oracle leavers reports, structures employee data, and filters it by location for efficient validation. The system checks employee names against SharePoint documents using a RAG pipeline and automatically sends email alerts for mismatches or continuity risks. I also configured cloud deployment (Azure/AWS), DevOps pipelines, scheduled execution, and thorough edge-case testing.

• Automation AI-Powered Dashboard

Built a full-stack application for automotive insurance analysis with real-time, interactive dashboards such as bar, pie, line, scatter, and heatmap charts. Integrated AI models trained on real datasets to predict costs and risks based on vehicle, driver, and city-specific factors. The platform was fully containerized with Docker, ensuring scalability and smooth deployment.

• Payments Chatbot

Contributed to a RAG-based chatbot capable of parsing and analyzing multi-thousand-page Mastercard interchange PDFs to extract fee codes and financial insights. Implemented an adaptive AI search module with dynamic filters, developed a modern responsive Next.js interface, and documented scalable API endpoints. Also supported deployment using Docker, Devbox, WSL, and GitLab pipelines.

• Smart Librarian

Created an AI-powered book recommendation system using OpenAI APIs and a RAG engine to answer queries and generate personalized suggestions. The backend integrates ChromaDB for embeddings search and supports speech-to-text, text-to-speech, and image generation features. Connected the FastAPI backend to a Next.js frontend to deliver a smooth and accessible user experience.

• Accelerator Solution Project

Built a modular Strapi backend exposing REST APIs for managing accelerators, users, reviews, and related resources. Implemented authentication, role-based access, a multi-filter search system, and a complete review and rating module. Additionally, Integrated n8n automations to power the chat assistant for automated responses, FAQs, and notifications.

• Project focused on improving reliability and maintainability by introducing structured automation framework aligned with Test Automation Pyramid. Developed automated tests in JavaScript and Playwright, designed with clean code principles for clarity and scalability, and complemented automation with manual testing to cover edge cases. This combined approach strengthened test coverage, reduced regression risks, and enabled faster, more stable release cycles.

• Tekla Structures is a large-scale BIM application used for 3D structural modeling. My work focused on enhancing the computational geometry engine, expanding the feature set, and improving application stability. Implemented new tools requested by users, resolved complex 3D geometry bugs, and optimized legacy components for better performance and maintainability. The role required advanced knowledge of vector math, trigonometry, and 3D transformations for algorithms involving intersections, distances, and spatial relationships. I also improved UI workflows, aligned new functionality with architectural standards, and contributed to CI/CD integration by adding automated tests.
