What we do
AI & LLM integration
Add language-model features to your product: chat assistants, document Q&A and retrieval pipelines, agent workflows, and evaluation. We work with Claude, GPT, Gemini, and open-source models.
Full-stack product development
Web applications built end to end — React and Next.js frontends, APIs, databases, and cloud deployment on Vercel, AWS, and GCP. From first prototype to production.
Technical advisory
Hands-on technical leadership when you need it: architecture and code reviews, AI adoption strategy, build-vs-buy decisions, and help hiring and evaluating engineers.
λ.products
Products
MultiLLM
A Chrome extension that sends one prompt to Claude, ChatGPT, and Gemini at the same time and shows their answers side by side, using your existing logins. Your prompts and history stay on your device.
λ.about
About
Y Lambda is the independent consulting practice of Elliot Eckholm, a software engineer focused on applied AI. We keep engagements small and hands-on: the person you talk to is the person who designs and builds your product.
Y Lambda is operated by Ylambda Tech LLC, based in San Diego, California.
λ.engagements
How engagements work
Most projects start with a short scoping call, followed by a written proposal with deliverables and pricing. We bill either a fixed project fee or an hourly rate, invoiced securely through Stripe; advisory work is billed monthly. You can end an engagement with written notice at any time and pay only for work completed. For questions about billing, invoices, or refunds, email contact@ylambda.com.
