One accountable lead.
Every project has a single senior lead who owns it from the first call to the last deploy. You always know who to ask.
CLEAR OWNERSHIPLemonberry Labs is a small studio of highly experienced engineers and product people, founded and led by Ran Magen. We make products of our own, and we build, automate and coach for clients.

I’m Ran Magen, the founder of Lemonberry Labs. I have spent more than 25 years building scalable systems, shaping products, and taking ideas from nothing to launch, at Coinbase, Twitter, Apollo GraphQL and AWS. I am known for distributed systems, backend infrastructure and developer productivity platforms, and I can work at nearly any layer of the stack.
I do my best work where engineering meets product: asking the right questions, challenging assumptions, and moving a project forward with a clear goal.
I started the studio to build products of my own and to bring that experience to other teams. Founding companies with paying customers taught me what engineering work a business needs. I like to learn, to collaborate, and to write software that lasts.
I spent my career on the systems other engineers build on, at companies where a mistake reaches millions of people, and then founded two companies of my own.
An AI learning app for kids. I run the technical side of the company: the Go backend, the cloud infrastructure, and how we ship.
I build, launch and support products with paying customers, Lemonvite among them, and I lead every client project. It taught me what engineering work a business needs.
I was the technical lead for backend engineering productivity. I led the migration to GraphQL Federation, set Protobuf standards across more than 700 repositories, and founded the Server Foundations Guild.
I worked on backend infrastructure and Federation, and wrote the next-generation Federation gateway in Rust.
I built AWS Elemental MediaConnect, a live video transport service, from its first line of code.
I was the tech lead for Timelines infrastructure: Home, Profile and Notifications. I owned tweet fanout, the system that writes each new tweet into its followers’ timelines, for hundreds of millions of users.
I built distributed systems at Dapper (acquired by Yahoo), my6sense, and Worklight (acquired by IBM), after eight years building for the web.
A small core team keeps the work focused. A trusted network gives us range when a project needs it.
Every project has a single senior lead who owns it from the first call to the last deploy. You always know who to ask.
CLEAR OWNERSHIPWe staff each project from a close network of senior engineers, AI researchers and product people we have worked with for years.
A SENIOR NETWORKWe try new tools on our own products first, so the risk is found before it reaches your project.
FAST LEARNING LOOPSA small studio has no approval chain. You ask a question and get an answer from the person doing the work.
RAPID EXECUTIONTests, monitoring, documentation and security are part of the work, at the pace of a small team.
QUALITYWe build and run products of our own, so we live with the results of our technical decisions long after launch.
