About

I build AI applications that connect language models, business data and useful software workflows. My background in data analysis, backend development and quality assurance shapes how I approach each feature: understand the requirement, prepare the data, build the integration and test the behaviour. AI APPLICATION DEVELOPMENT • Hands-on work with retrieval-augmented generation (RAG), prompt engineering, GPT fine-tuning and AI evaluation. • Data preparation and response-quality analysis, including accuracy, relevance, consistency and edge cases. • Currently learning and implementing vector retrieval with PostgreSQL and pgvector. FULL-STACK & INTEGRATIONS • Develop web interfaces, backend features and REST API integrations using Next.js, TypeScript, JavaScript and Node.js. • Use AI-assisted development to turn requirements into working features, supported by code review, debugging and functional testing. DATA & SOFTWARE QUALITY • Write SQL queries, clean and validate data, investigate inconsistencies and prepare analytics reports. • Apply functional, regression and API testing experience to application workflows and AI outputs. HOW I WORK I take ownership of understanding the problem and validating the solution. I enjoy connecting the AI, application and data layers, and improving my engineering skills through hands-on implementation. CAREER DIRECTION Focused on AI Engineer, Generative AI Developer and AI application development opportunities, with remote work preferred.
