How we help businesses like yours

Our Services

AI Products & Integration

From LLM-powered features to full AI pipelines — we design, build, and ship AI products that work in production, not just in demos.

Web & Mobile App Development

End-to-end development of web apps, APIs, and internal tools — architected around your business logic and built to scale from day one.

Web3 & Blockchain

Smart contracts, DeFi protocols, dApps, and token systems — built on Ethereum, Solana, and beyond. From whitepaper to mainnet.

Legacy Modernization

We take aging codebases, AI-generated slop, and unmaintainable monoliths and turn them into clean, production-ready, scalable systems.

Cloud & DevOps

CI/CD pipelines, container orchestration, and cloud architecture on AWS, GCP, and Azure — engineered to cut costs and eliminate the fires nobody wants to fight at 3am.

Automation & Workflows

From data pipelines to CI/CD to business process automation — we replace manual workflows with reliable, self-running systems.

CTO-as-a-Service

For non-technical founders who need a technical co-founder. We define your architecture, evaluate vendors, build your tech roadmap, and de-risk every major engineering decision.

Security & Technical Due Diligence

Code audits, security reviews, and pre-funding or pre-acquisition technical diligence — we find the issues that don't show up in a demo, before they show up in production.

Embedded Engineering

Seasoned engineers who work inside your team — no recruiting lag, no onboarding overhead. We embed directly and ship alongside you across product, systems and infra.

Don't Just Take Our Word For It

See What The Clients Say

“I've brought GrayLining onto several projects for my agency, and it's the same story every time — they take ownership, communicate clearly, and deliver clean work on time. I trust them enough to hand off a project and not worry about it.”

Anantha K.A.

Founder, Pixel Technologies

“I've worked with GrayLining on several projects, and it's been a great experience every time. Whenever we need extra engineering support or someone to take ownership of a complex technical problem, they're the first team we reach out to. They're easy to work with, communicate well, consistently deliver quality work and are very professional. It's been great having a technical partner we can rely on, and I wouldn't hesitate to recommend them to anyone looking for experienced developers or technical leadership.”

Taras P.

CEO, Pectora

“One of the best python devs on upwork. Gets all issues resolved and gets the job done. Worked with him for 4 months on a medium term project to develop an auto trader for crypto exchange which was in a bad state. He resolved all problems with this custom trading system and got it up and running.”

Chris J.

Founder, CEO, Next Layer

“Our CRM demoed well and customers were already using it, so we thought it was solid. We asked GrayLining to fix a couple of bugs, but they traced them back to the real cause and found issues we hadn't caught. They fixed what needed fixing, and now the product can actually stand up to real usage. I trust it in a way I didn't before.”
