Master the
Hidden 90%
of Backend Engineering.
Most tutorials teach you how to code. We teach you how to architect. From local dev to multi-cloud deployments, master the industrial stack.
Industrial Patterns
Learn the exact design patterns used in production-grade systems at high-scale startups.
Deep Observability
Go beyond console.log. Master telemetry, distributed tracing, and real-time monitoring.
System Thinking
Stop thinking in lines of code. Start thinking in nodes, queues, and latency boundaries.
Specialized Tracks
Choose your weapon. Master the ecosystem.
Node.js Mastery
Master asynchronous architecture and high-scale Express deployments.
Python Mastery
Rapidly build secure, type-safe backends with the power of FastAPI.
Go Mastery
Achieve legendary performance with Gin and cloud-native concurrency patterns.
More Tracks Coming
Java, Rust, Zig, and more are being architected as you read this.
The Roadmap to
Senior Engineer
Our curriculum isn't just a list of videos. It's a progressive system designed to build your mental model of distributed systems.
Core Foundations
Master language-specific internals and the event loop.
API Architectural Design
Beyond REST. Master GraphQL, gRPC, and WebSockets.
Scalability & Persistence
SQL, NoSQL, Caching strategies, and Sharding.
Distributed Systems
Message queues, Event sourcing, and Microservices.
The Pro Community
Join thousands of backend engineers who have leveled up their careers with Dely.
"Dely's roadmap is the best I've seen. It doesn't just teach code; it teaches the thinking behind the code."
"The Go track saved me weeks of architectural research. The distributed system patterns are pure gold."
"We use Dely to onboard all our junior engineers. The consistency across languages is unique."

Common Questions
Everything you need to know about starting your journey.
Is this course suitable for beginners?
Phase 1 (Basics) is designed for those who know the language syntax but haven't built systems yet. If you are totally new to coding, we recommend learning the language basics first.
How long does it take to complete a track?
Each track (Node, Go, Python) is roughly 25-30 hours of dense educational content. With practice projects, we recommend 4-6 weeks per track.
Is there a lifetime access option?
Yes! Our Pro Yearly plan provides 12 months of access which is enough for most to master all tracks, and we offer student discounts for long-term learners.
Do you provide certificates?
Yes. Upon completing all phases and passing the final architectural challenge of a track, you receive a verified digital certificate.
