System Design

Saarathi's 8-week System Design course gives mid-level and senior-track engineers the frameworks, case studies, and mock interview practice needed to reason confidently about distributed systems, and to communicate that reasoning in the exact format system design interviews use.

Why System Design Skills Matter in Nepal's Engineering Market

• Senior engineering roles at Nepal's established software companies, product startups, and outsourced tech teams are consistently harder to fill than junior roles, and system design ability is the main differentiator.
• Remote senior roles with international employers almost always include 1-2 system design rounds. Engineers who prepare specifically for this format convert significantly better than those who only practice coding rounds.
• Tech leads and engineering managers who cannot reason about trade-offs at the architecture level become bottlenecks rather than force-multipliers. System design training directly improves engineering leadership.
• The rise of AI-powered products means engineers are increasingly asked to design LLM pipelines, RAG systems, and embedding architectures, system design thinking now covers this territory.

What You Learn in Saarathi's 8-Week System Design Program

The course is structured around two phases: three weeks of distributed-systems foundations (the shared primitives, storage and consistency, and the network path and the edge, paced so the early weeks go deep on fewer ideas), then five weeks of scaling, architecture, resilience and interview mastery (sharding and caching, async messaging and microservices, security and resilience, real case studies, the coding round, mocks and capstone).

• Distributed systems fundamentals: scalability, load balancing, caching, database sharding, replication, CAP theorem, message queues, API design, and observability.
• Infrastructure and trade-off reasoning: SQL vs NoSQL selection, CDN architecture, rate limiting, consistent hashing, serverless patterns, and distributed tracing.
• Real-world case studies: Twitter/news feed, WhatsApp/chat, YouTube/video streaming, Uber/ride-sharing, Dropbox/file sync, and a production-scale LLM/RAG system.
• Modern system design: LLM application architecture, RAG pipeline design, vector store integration, the AI systems that senior engineers are now asked to design.
• Interview mastery: the STARD framework (Scope → Trade-offs → Architecture → Rate estimation → Deploy and monitor), communication strategies, mock system design interviews in 45-minute format, and company-specific rubric awareness.

Why Saarathi Academy for System Design Training in Kathmandu

• Weekly 1-1 mock system design interviews simulate the exact pressure and format you will face. Most candidates practice by reading, but design interviews require thinking out loud, drawing diagrams, and structuring answers under time pressure.
• Small batches mean your design decisions get challenged and discussed. Real system design improvement comes from having assumptions questioned, not from passively absorbing frameworks.
• The STARD framework gives you a structured template for approaching any system design problem, so you spend interview time designing, not figuring out where to start.
• LLM and RAG system design is included because it is increasingly part of what senior engineers are asked to design today, not a distant specialisation.

Career Outcomes

This course directly targets Software Engineer II, Senior Software Engineer, and Staff/Principal Engineer trajectories.

System design ability is not just for interviews. Engineers who think at the system level ship better features, make better trade-off calls, write better technical specifications, and mentor junior engineers more effectively. The investment compounds across your entire career.
