I worked as a Senior AI Developer at bdCoder, where I was involved in building and improving AI-based applications for different types of projects. My work started from understanding what the client or product actually needed and then figuring out the best way to turn that idea into a working solution. I worked on AI chatbots, AI assistants, LLM-based applications, AI agents, RAG systems, automation workflows, API integrations, and other AI-powered features for web and mobile applications. I also worked with Python, OpenAI APIs, backend services, databases, REST APIs, and different third-party services. A big part of my job was making sure the AI was not only working in a demo but was actually useful in a real application. I worked on improving prompts and responses, connecting AI with business data, handling different user situations, fixing issues, and making the overall system more reliable and easier to maintain. I also worked closely with designers, developers, and clients throughout the development process. I helped with technical decisions, development, testing, debugging, API integration, performance improvements, and deployment. This experience gave me strong practical knowledge of AI development and helped me become comfortable taking a project from an initial idea through development and into a working product. It also taught me how to deal with changing requirements, solve unexpected technical problems, and focus on building solutions that are genuinely useful to the end user.
