Trusted by Web3 Projects
Delivering high-impact results for protocols and DAOs.
"They built our SDK from scratch and it cut third-party integration time in half. The frontend handled $20M in liquidity without a single critical bug. No drama, no delays — just clean work."
Daniel
Protocol Lead, Ajna Labs
"We brought the Ninja team in for a time-bound refactor of a messy Next.js codebase. They cleaned up years of technical debt in weeks and left the code in a state our team could actually maintain."
James
Engineering Manager, Mode Network
"Their lead integrated with our 12 developers and kept the frontend stable at 5 million monthly visitors. Bugs dropped 25%, productivity went up 30%. They deliver what most teams only promise."
Kaal
Project Coordinator, Shiba Inu
"The jackpot UI they built runs on some of the biggest iGaming platforms in the world. Vanilla JavaScript, no framework bloat, pixel-perfect on every device. These guys know how to ship production code."
Mark
Product Owner, Games Global
"The Web3 Ninja engineers joined our team of 15 and immediately started improving things nobody asked them to fix. They mentored 4 of our frontend devs and the quality of PRs changed within a month."
Rudi
CTO, Linum Labs
"We needed a dashboard connecting vesting, farming, and rewards to Ethereum smart contracts. They shipped it across React, Next.js, and Python — and it just worked. No excuses, no scope creep."
Andrea
Founder, Omnia DeFi
"They refactored our entire SPA and saved us roughly €50,000 in ongoing maintenance costs. The codebase went from something nobody wanted to touch to something juniors could onboard to in a week."
Thomas
Managing Director, iControlApp
"Solid team that understood the complexity of our scientific data platform from day one. They built search interfaces that researchers actually use — not just demos that look good in a pitch deck."
Erik
Technical Lead, Elsevier
"The Ninja collective mentored me for 4 months. No hand-holding, but no abandonment either. Real projects, honest feedback. Three of us from the same cohort got placed as junior devs."
Sofia
Junior Frontend Developer, Former Mentee
