Harsh Jha

Senior AI Engineer & AI Tech Lead | Full-Stack Systems Architect (Go · .NET · Angular · LLMs)


🧭 Professional Summary

Senior AI Engineer and AI Tech Lead with 3+ years of experience architecting and shipping production systems that combine high-performance backend engineering with applied AI product development. Currently leading a cross-functional team of 10 engineers at Simplyphi, a UK-based product startup, spanning AI engineering and full-stack development.

I specialize in taking AI products from concept to production — designing LLM-powered systems, RAG pipelines, and multi-agent architectures, while also owning the underlying distributed systems, microservices, and scalable APIs that make them reliable in the real world. I bridge the gap between "AI that works in a demo" and "AI that works in production."


👔 Leadership & Ownership

  • Leading a cross-functional team of 10 engineers across AI Engineering and Full-Stack Development, owning delivery from architecture through production release.
  • Own technical architecture and project planning for AI and full-stack initiatives — setting technical direction, scoping systems, and de-risking delivery timelines.
  • Mentor and upskill developers through structured code reviews, architecture walkthroughs, and pairing — raising the team's engineering bar on clean architecture, testing, and AI system design.
  • Drive AI product development end-to-end, from ideation and stakeholder alignment through design, implementation, evaluation, and deployment.
  • Champion engineering best practices — SOLID principles, clean architecture, dependency injection, and repository patterns — across both AI and traditional backend services.
  • Act as the technical bridge between product stakeholders and engineering, translating business requirements into system designs and AI workflows.

🤖 AI Engineering Expertise

LLMs & Generative AI LLM Application Development · Prompt Engineering · Function Calling · Structured Output Generation · Fine-Tuning Concepts · Evaluation Frameworks · Guardrails & AI Safety · AI Observability

Retrieval & Knowledge Systems Retrieval-Augmented Generation (RAG) · Semantic Search · Embedding Models · Vector Databases (Pinecone, Weaviate, ChromaDB, FAISS) · Knowledge Graph Integration

Agentic Systems AI Agents · Multi-Agent Systems · Model Context Protocol (MCP) · LangChain · LangGraph · LlamaIndex · AI Workflow Automation

Model Providers & Platforms OpenAI APIs · Anthropic Claude APIs · Google Gemini APIs · Hugging Face Transformers

I design AI systems the way I design backend systems — modular, observable, and built to handle failure gracefully, not just to work on the happy path.
