Sound Familiar?
❌Stuck in Maintenance Mode
You fix bugs others created. You modify existing endpoints. But you never get to design the system from scratch.
❌Silenced in Architecture Meetings
When Seniors discuss Sharding, CAP Theorem, or Eventual Consistency, you stay quiet because you've never built it.
❌The "Senior" Title Gap
You have the years of experience. You have the title. But you know you lack the deep system design skills of a true Staff Engineer.
How The Simulation Works
We mimic the exact workflow of a Senior Engineer at a top tech company.
The Product Spec (PRD)
You don't get a tutorial. You receive a detailed Product Requirement Document (PRD) with vague requirements and strict constraints.
The RFC (Request for Comments)
Before writing code, you write a Design Doc. You choose the architecture, database, and trade-offs. You defend your choices.
The Implementation (Sprint)
You build the system. No shortcuts. You handle race conditions, concurrency, and failures. You use Docker, Postman, and Cloud tools.
The Code Review (Async Feedback)
You submit a Pull Request. You get feedback on your code quality, security, and scalability. You iterate until it's production-ready.
The 12-Week Journey
Three modules. Twelve production systems. One goal.
Module 1: The Core (Data & Protocols)
Handling data correctly before scaling
The "YouTube" Ingest
Handle 10GB uploads on a server with only 512MB RAM without crashing.
The "Slack" Scraper
Parse metadata from untrusted URLs without exposing internal networks to SSRF attacks.
The "Auth0" IDP
Issue verifiable security tokens for a distributed system without shared database lookups.
The "Midjourney" Queue
Process heavy tasks in the background without blocking the user interface.
Module 2: The Scale (Concurrency & Real-Time)
Multiple users competing for the same resources
The "Ticketmaster" Engine
Handle 1,000 concurrent requests for a single seat without selling it twice.
The "eBay" Auction
Broadcast live bid updates to thousands of viewers in real-time using WebSockets.
The "Cricbuzz" Scorecard
Push live score updates to millions without polling using Server-Sent Events.
The "DoorDash" Tracker
Find the 5 nearest drivers from millions of locations in under 100ms.
Module 3: The Cluster (Distributed Systems)
Logic that survives across multiple nodes
The "Ledger" System
Build an audit trail where every change is immutable and you can time-travel to any point.
The "Stripe" Deduplicator
Process payments safely, ensuring users are never charged twice for the same click.
The "LaunchDarkly" Flags
Toggle features on/off without deploying. Gradually roll out to 10%, then 50%, then 100%.
The "Microservices" Mall
Build a complete e-commerce backend with multiple services communicating together.
Code is Temporary.
Architecture is Forever.
We focus on the concepts that stay the same even when the frameworks change.
Syntax is Cheap. Design is Expensive.
AI can write code. AI cannot negotiate trade-offs. We teach you the immutable principles of Distributed Systems that haven't changed in 20 years.
Frameworks vs. Fundamentals
Today it's Next.js. Tomorrow it's something else. But the physics of software—Latency, Throughput, and Consistency—are forever.
Meet the Mentor
I am the Head of Engineering at Jobbatical OÜ, with 8+ years of leadership and 15 years of total experience in the software industry.
"Building APIs is just the start. The real challenge is shipping reliable, production-ready systems that scale."
I built learnwithparam to bring that European engineering culture and rigor to you. No fluff, just production engineering.

The Final Polish:
Career Acceleration Skills
Coding gets you the interview. Process gets you the offer.
To land high-paying Remote Roles, you need the skills of high-leverage engineers.
Asynchronous Communication
You will learn to explain complex technical concepts clearly in writing (via PR descriptions and RFCs). This is the #1 skill for remote work.
Trade-Off Analysis
There is no 'Right Answer.' There are only Trade-offs. You will learn to defend your decisions (e.g., 'I chose Eventual Consistency because Availability was critical').
Constraint-Based Engineering
You will learn to deliver value *within* strict limits (Memory, CPU, Time). This proves you are pragmatic, not just academic.
Documentation
You will build a 'User Manual' for every system. Seniors write docs that save the team hours of meetings.
FAQ
Will this help me get a job?
We don't sell job guarantees; we sell Competence. When you walk into an interview and can explain exactly how you designed a Sharded Database or an Idempotent Payment Switch, you stand out immediately.
I have 5 years of experience. Is this for me?
Yes. Many engineers have '1 year of experience repeated 5 times'. If you haven't built Circuit Breakers, Idempotency keys, or Async Queues from scratch, this will fill the gaps in your knowledge and prepare you for Staff/Senior roles.
Do I need a cloud account (GCP/AWS/Azure)?
No. We focus on Local Simulation. You can run everything on your laptop (yes, even a MacBook Air). The concepts apply universally to GCP, AWS, Azure, or bare metal.
Can I use any programming language?
Yes. The Specs describe the Input and Output. You can implement the logic in any language you want to master—whether that's Go, Rust, TypeScript, Java, C# or any other language. You choose the tool; we provide the blueprint.
