At Toptutors, I was brought on as a Backend Software Engineer to modernize the platform's search infrastructure and improve overall data processing capabilities. My most significant contribution was designing and implementing advanced Retrieval-Augmented Generation (RAG) pipelines. By integrating sophisticated vector stores and embedding models, I successfully transitioned the platform away from traditional keyword search mechanisms toward an intelligent, context-aware semantic search system capable of handling complex, multi-context queries seamlessly. Beyond AI integration, I was responsible for architecting robust backend infrastructure to handle high traffic volumes. I developed two independent microservices utilizing Go and Flask, specifically engineered to process large, concurrent data payloads efficiently. These microservices were rigorously tested and optimized to ensure low-latency responses, reliably handling upwards of 5,000 daily queries without performance degradation. My work here drastically improved the platform's user experience through faster, more accurate data retrieval, while also providing the company with a resilient backend foundation built to scale.

As a Software Engineer at Rantir, my role centered on accelerating full-stack development cycles and automating labor-intensive workflows through intelligent system design. I led the development of four distinct Next.js web applications, focusing on establishing strict, type-safe API contracts. By leveraging OpenAPI and Orval specification generation, I completely eliminated the need for manual API typing across more than 20 distinct backend routes. This drastically reduced frontend-backend integration errors and significantly sped up feature delivery. Furthermore, I spearheaded an initiative to automate the company's content management operations. I successfully deployed GPT-4 models into our production environment, creating a pipeline that automatically parsed, structured, and formatted content. This AI-driven solution completely replaced tedious manual data entry workflows, saving countless hours of human labor and minimizing operational friction. My tenure at Rantir demonstrates my ability to blend modern web frameworks with AI integrations to solve real-world business bottlenecks.
