Real production problems. Built from what 100s of recruiters asked us for.
You learn each module by solving scenarios like these, in whatever language you work in. Open any module to see them.
1Systematic Query Profiling
Never fear databases again.
3 scenarios
- What do you do when your queries take over 10 seconds to execute?
- How do you handle performance issues with 100,000+ records in your database?
- How do you optimize queries behind 1,000,000+ transactions per hour?
2API Benchmarking Framework
Find bottlenecks before they affect users.
3 scenarios
- What do you do when p50 response times exceed 200 ms and p99 hits 1 second?
- Simulate security threats like DDoS and measure the impact on API performance.
- Track error rates at 10,000 requests per second and find the failure patterns.
3Responsive Application Craftsmanship
Handle time-intensive tasks.
3 scenarios
- Image uploads run synchronously and the UI stalls. How do you offload the work and keep the app responsive?
- Track product views and purchases in real time for recommendations, offers and fraud detection.
- Design real-time transaction processing for a bank that validates every transaction and blocks suspicious ones as they happen.
4Comprehensive DevOps Blueprint
Streamline your development pipeline.
7 scenarios
- Automate pipelines to handle 100 deployments a day with zero downtime.
- Your primary database crashes and you have 24 hours of transaction logs. How do you recover?
- Secure sensitive data like card numbers, both in transit and at rest.
- Fix "It works on my machine" for the whole team.
- Rate-limit an IP that sends 10,000 requests a minute.
- Set up real-time logging and alerting for 5,000 transactions per second.
- Test and monitor 30+ microservices and catch failures fast.
5Resilient Cloud Architecture
Build for scale, reliability and robustness.
3 scenarios
- 500 users hit your backend at the same moment. What happens?
- Architect for 99.99% uptime, then prevent and recover from failures.
- Stay compliant with GDPR and CCPA while operating globally.
6AI Workflow Integration
Spend less time writing and more time thinking.
3 scenarios
- Build and test prototypes for a new feature in half the time.
- Use AI in code review to enforce best practices and keep quality consistent.
- Use AI to debug a codebase with thousands of dependencies.
7DSA Patterns Mastery
We made it fun.
7 scenarios
- Calculate time and space complexity.
- Implement stacks, queues and linked lists from scratch.
- Add two pointers, binary search and DP to your toolbelt.
- Traverse trees and graphs.
- Query a 100,000-record hierarchy, like an org chart or a file system.
- Find influencers and communities in a 500,000-user social graph.
- Solve a 9×9 Sudoku with backtracking.
8Interview Power Prep
We've got you covered.
7 scenarios
- Build a portfolio that shows your technical depth.
- Present projects by their results and your contribution.
- Optimize your resume for the roles you want.
- Explain technical concepts clearly.
- Answer behavioral questions with the STAR method.
- Negotiate salary and benefits.
- Use mock-interview feedback to improve.
Write lots of code. Scale one app through three milestones.
A clean schema, solid APIs and queries that don't fall over.
Caching, async jobs, benchmarks and a pipeline that deploys without downtime.
Resilient cloud architecture with 99.99% uptime, observability and real failure recovery.
Videos don't teach you to build. Reviews do.
Each assignment follows the same loop. You stay on a task until the review comes back clean.
- Step 1
Pick up a task
A real backend problem with a spec, constraints and a target to hit, like p95 latency or zero data loss.
- Step 2
Build it your way
Java, Python, Go or Node.js. Use docs, Google and AI. Nobody gives you a walkthrough to copy.
- Step 3
Get line-by-line review
A senior engineer reads your code and asks the questions an interviewer or tech lead would.
- Step 4
Prove it under time
Timed assessments and mock interviews check that the skill stuck. Doubt sessions get you unstuck in between.
Swapnil Agarwal
Give me a developer who is hands-on with SQL and can help scale our product. I don't have time for handholding. I need someone who can hit the ground running on day one.
I get requirements like this every day, and most are hard to fill because candidates lack depth. So I built the backend course I wish those candidates had taken. No fluff. You learn by doing.
Founder, Roc8 Careers. Placing developers since 2020.

Do the first week. If it isn't the hardest, most useful week of your year, ask for a full refund within 7 days.
- Review on every submissionThe feedback books and YouTube can't give you.
- Timed assessmentsMock-interview practice under real time pressure.
- A structured curriculumBackend development end to end, in 8 modules.

Practical questions
Can a beginner join?
No. You need professional work experience as a developer to make the most of this program. Any kind counts: frontend, mobile, or even backend itself.
Is there a refund policy?
Yes. If the program isn't working for you in your first week, ask for a full refund within 7 days.
Should I pick the 5-month fast track?
Only if you already have backend experience and are comfortable with databases at scale. It costs half because it's half as many months, but the work is the same.
