Introduction
I have over 12 years of experience in software development, specializing in full-stack technologies such as C#, Angular, React.js, JavaScript, Node.js, and Python. I’ve worked extensively with frameworks and tools like Flask, FastAPI, Web API, Elasticsearch, MongoDB, RethinkDB, Redis, Neo4j, and OrientDB. Recently, I’ve been leveraging Snowflake’s data warehousing capabilities to build scalable solutions for advanced data analysis and management. One of my most impactful achievements was designing and developing a sentiment analysis platform using Python and Neo4j, which visualized COVID-19-related insights through graph-based data relationships. In addition, I have strong experience building SaaS applications, deploying cloud-native solutions on Microsoft Azure, and integrating AI-driven services using the OpenAI API. I’ve also focused on backend performance optimization using k6, MediatR, and Entity Framework in .NET Core. I’m passionate about building clean, efficient, and scalable systems that solve real-world problems and deliver measurable impact.
