Founding Engineer/ Chief Technology Officer
TellMe AI Limited, United Kingdom
InnovateUK funded tech startup building a visitor centric point and discover experience for visitors at museums and attractions.
Fine-tuned and integrated the provided computer vision components (embeddings, ONNX inference, and model outputs) into the mobile web application, optimizing performance and reducing battery drain on low-end devices by over 50%.
Designed and built the full mobile-first, edge-optimized web application for a point-and-discover experience used in museums and cultural spaces, including the frontend (Next.js) and backend (FastAPI) along with all supporting infrastructure.
Developed the complete backend architecture using Python (FastAPI) and MongoDB, covering APIs, data models, content pipelines, and embedding management workflows.
Built the comprehensive Admin & Content Management Portal, enabling curators and internal teams to manage collections, metadata, assets, geometries, and discovery logic through a streamlined interface.
Architected and implemented the full CI/CD and DevOps ecosystem using GitHub Actions, with automated builds, deployments, testing pipelines, and environment management.
Delivered a reliable and scalable cloud infrastructure on AWS, including Amplify, CloudFront, S3, EC2, CloudWatch, and AWS Backup, ensuring performance, monitoring, and resiliency across the entire product.
Designed and built a rule-based Retrieval-Augmented Generation (RAG) Prompt Engine—a dynamic prompt construction system using definitions, templates, rules, and composable components—to power the conversational AI layer of the application.
Delivered all core components—frontend, backend, admin portal, DevOps pipelines, AWS infrastructure, integrations, and performance optimizations—within a rapid 4–6 month timeline to achieve a production-ready MVP.
