Hire AI developers: dedicated engineers from a founder-led team

Hire AI developers who ship to production

Our engineers build RAG search, AI agents, LLM integrations and the full-stack software around them, and they work in your repositories, your tickets and your chat. You get a monthly team led by a founder with 9+ years in AI and software, not a pool of contractors you have to manage alone. The same team has shipped production AI for legal tech, pharma and healthcare clients.

Hire AI engineers for generative AI, LLM and agent work

Hire AI engineers for the work that turns a model into a product. Our generative AI developers and LLM developers build retrieval over your documents (RAG), structured extraction, chat inside your app and AI agents that call tools and hand uncertain cases to a person. Hire ChatGPT developers for work on OpenAI's models, or engineers for Claude on AWS Bedrock; we choose the model by testing it on your data.

• RAG over case documents for DecoverAI, a legal AI platform
• A multi-agent coding runner with a judge LLM for BlackBox AI, as AI agent developers
• Claude on AWS Bedrock for pharmacovigilance literature screening, with human sign-off
• LLM parsing of water quality reports for Water Advisor AI, with the model and cost logged per call

Hire machine learning engineers and prompt engineers

Hire machine learning engineers when a general model is not enough: we have fine-tuned a small open model (Phi-3.5) for a narrow pharma task and benchmarked it against a larger one. Most teams need less than that, and that is where prompt engineers come in. Hire prompt engineers from us to write and test prompts against an evaluation set of your own examples, so a change to a prompt or a model is measured before it ships.

Rates for junior, mid and senior engineers

• Junior, $20/hr: features from a clear spec, tests, UI work, integrations
• Mid, $25 to $30/hr: features end to end, APIs, AI integrations, code review
• Senior, $30+/hr: architecture, RAG and agent systems, infrastructure, technical lead
• DevOps specialist, $45/hr: CI/CD, infrastructure as code, Kubernetes, cloud cost
• Fractional CTO, from $5,000/mo for up to 40 hours a month: technical direction, hiring, architecture and vendor decisions

Model, API and cloud costs are billed to your own accounts. You approve the team mix before work starts.

How a monthly team works

1. 1A short call to agree scope, the skills you need and how many hours a month (minimum 80).
2. 2We propose a team mix (for example one senior and one mid engineer), and Yash leads the engagement.
3. 3The team works in your repositories and tools from week one.
4. 4Every week you get a demo and a written changelog.
5. 5You scale the hours up or down with 2 weeks' notice, from a minimum of 80 hours a month.

The code is yours from the first commit.

Fractional CTO services

A fractional CTO is a part-time technical leader for a company that needs senior technical judgement but not a full-time hire. Yash offers this from $5,000/mo: technical strategy and roadmap, architecture reviews, hiring and interviewing engineers, choosing vendors and AI models, and keeping delivery on track with your team or ours. He already plays this role inside long-running client engagements. The $5,000/mo fee includes up to 40 hours a month.

DevOps outsourcing

Outsource DevOps to us at $45/hr, the specialist rate: CI/CD pipelines, infrastructure as code with AWS CDK, Terraform or Bicep, Kubernetes on AWS EKS, and AWS cost reviews. Certifications: CKAD, AWS Certified Cloud Practitioner, Microsoft AZ-900. See DevOps consulting for fixed-price setups from $1,500.
