From Learners
to Lead Engineers.

Arjun Mehta

Senior Software Engineer @ Google

"The distributed systems patterns I learned here were literally the questions I faced in my Google interview. Dely shifted my mindset from a weekend coder to a system architect."

Sarah Jenkins

Full Stack Lead @ Stripe

"I always struggled with scaling Node applications correctly. Dely's production-grade lessons showed me how to handle concurrency and observability like the pros do."

James Whitfield

Backend Engineer @ Graphcore

"I had applied to over 60 companies with no callbacks. The Job Training Program gave me a custom roadmap, rebuilt my GitHub, and drilled me through mock interviews. Graphcore offered me the role after my second round."

Elena Rodriguez

Staff Engineer @ Coinbase

"I replaced three expensive bootcamps with one Dely subscription. The depth of the Python advanced track is unmatched. It truly bridges the gap to Staff level."

Sophie Hargreaves

Software Engineer @ Sage Group

"I was a self-taught developer stuck in tutorial hell. The 1:1 mentorship sessions kept me on track and the application strategy was something no bootcamp had ever taught me. Sage Group hired me within 10 weeks."

Priya Das

Software Consultant @ Self-Employed

"Client projects became much smoother once I started implementing the architectural roadmaps from Dely. My value as a consultant has skyrocketed."

Marcus Thorne

Senior Backend Engineer @ Netflix

"Scaling Node.js services to handle millions of concurrent requests felt impossible until I went through Dely's advanced tracks. The depth on event loop internals and observability is industry-leading."

Aisha Khan

Cloud Architect @ Meta

"The Kubernetes and Terraform modules helped me design resilient infra that handles millions of users. Meta's onboarding was much easier because of Dely."

David Park

Principal Engineer @ Airbnb

"Mastering system design patterns from real-world examples in Dely gave me the confidence to take on large-scale architectural projects at Airbnb."

Oliver Pemberton

Full-Stack Engineer @ Wise

"I knew system design was my weak spot and that's exactly what the program zeroed in on. Weekly check-ins kept me accountable. Three months later I was signing an offer at Wise with a 60% pay increase over my previous role."

Oliver Smith

Backend Architect @ Discord

"Building real-time WebSockets and handling millions of concurrent users can be brutal. Dely's specific lessons on high-concurrency systems are a must-have for any architect."

Maya Patel

Staff Backend Engineer @ Riot Games

"The complex logic of game backends requires top-tier architectural thinking. Dely provided the scaffolding I needed to move from Senior to Staff level at a world-class studio."
