“LLM-focused engineer who has shipped multiple production-grade AI reliability systems: an LLM output validation/monitoring service (FastAPI) with prompt versioning and failure analytics, plus a RAG feature using embeddings/vector DBs with retrieval thresholds, schema/context validation, and safe fallbacks. Strong in evaluation loops (groundedness, schema accuracy, human review) and scalable pipelines for messy document ingestion with observability and early detection of data quality issues.”

“Former tech professional and repeat founder who previously built Promote.co, pitched a marketplace-focused ad platform to Expa Ventures, and raised capital to build the product. Has spent the last two years independently developing and using stock market strategies, and is now looking to return to tech to solve meaningful, difficult problems.”

“Entrepreneurial candidate building an AI startup focused on helping companies find product-market fit. They are already at MVP stage with 3 beta customers and are using A/B testing for validation, showing early traction and a hands-on approach to customer-driven product development.”
