About Vignesh
AI Engineer Who Builds & Ships Market-Validated Products
I've shipped AI products that hit Product Hunt's front page (157K views), got accepted into Station F, and currently optimize enterprise AI systems for funded startups. Because I've been in the trenches building my own products, my work isn't just code; it's about creating tangible value that works in the real world.
- Proven Market Appeal: My AI-powered Mac app was featured by Product Hunt, gaining over 157,000 views and attracting users from Google and Facebook.
- Founder's Mindset: As a founder accepted into Station F (the world's largest startup campus), I think beyond technical implementation to focus on user experience, market fit, and your business goals.
For enterprise clients like Steerlab ($1.9M raised), I scale and refine high-stakes AI systems. I've designed LLM-as-judge evaluation pipelines, benchmarked model performance, and optimized their core systems using advanced techniques like RAG and fine-tuning. I am fluent in the full AI stack, from Python, Rust and cloud deployment on AWS/GCP.
My core services include:
- End-to-End AI Product Development: Taking your concept and delivering a fully-functional, user-centric MVP or V1 product.
- AI System Audit & Optimization: A comprehensive review of your existing AI pipeline to deliver measurable improvements in performance, cost, and reliability.
- GenAI & RAG Implementation: Building and deploying novel retrieval-augmented generation systems and other advanced language model features.
- Technical Prototyping & Validation: Quickly building a functional prototype to test a new AI concept and validate its feasibility with real users.
If you're looking for an engineer who takes ownership and drives your project to a successful launch, let's talk.
