#Stateful Programming

The SWE Interview Loop Round 4/7. The system design interview. Here’s how it goes and how to prepare. #systemdesign #csmajors #coding #programming

System design patterns you need to know Scale reads → caching, read replicas, indexing Scale writes → sharding, batching, async writes Real-time data → WebSockets, SSE, long polling Long-running work → queues, workers, workflows Reliability → retries, idempotency, circuit breakers Separate reads & writes → CQRS Once you know these patterns, you’ll see them everywhere. #systemdesign #csmajors #coding #programming

The Brutal Difference Between Junior and Senior Engineers Most developers think senior engineers just code faster or cleaner. That’s not the real difference. Junior engineers focus on building features. Senior engineers focus on preventing failures. They think about: Edge cases Traffic spikes Monitoring gaps Scalability Long-term maintainability The shift from junior to senior isn’t about writing more code. It’s about owning outcomes. Reliability over cleverness. Clarity over ego. Trade-offs over trends. If you want to grow as a backend engineer or move toward senior roles, start thinking in systems — not just features.

Want to know if your code looks "Junior" or "Professional"? 📘 Download my FREE High IQ Software Checklist here: https://henrikmdev.com/highiq Most C tutorials teach you syntax, but they never teach you how to build a product. If your project directory is a flat pile of files, you are suffering from something called Source Pollution. There are often layers of separation in architecture used by Senior Engineers. One helpful idea is to ensure your fellow developer can navigate your codebase in under 60 seconds. #softwarearchitecture #cprogramming #codingtips #softwareengineering #cleanarchitecture #projectmanagement #developerlife

System Design Interview 🚨 SQL vs NoQL 🤯 #softwareengineering #systemdesigninterviews

System Design is not just an interview topic. It’s how real-world software handles scale, failures, traffic spikes, and growth. If you want to grow from writing code → designing systems, start with these fundamentals: • Requirements & Trade-offs – Functional vs non-functional requirements, scale, latency, availability • API Design – REST vs gRPC, versioning, idempotency, rate limiting • Data Modeling – SQL vs NoSQL, indexing, sharding, replication • Caching & Performance – Redis, CDN, cache invalidation, TTLs • Scalability – Load balancers, horizontal vs vertical scaling • Reliability – Retries, timeouts, circuit breakers, fault tolerance • Async Systems – Queues, streams, pub-sub, eventual consistency • Architecture Patterns – Monolith vs microservices, CQRS, Saga • Security & Observability – Auth, metrics, logging, tracing • Cost Awareness – Performance vs cost, simplicity vs scale Whether you’re a student, working engineer, or interview candidate, learning system design early changes how you think about software. 👉 Save this as your system design roadmap 👉 Follow for DSA + System Design + real-world engineering #systemdesign #softwareengineering #backenddeveloper #coding #programming techcareers interviewprep distributedSystems

Everyone is running behind frameworks & trends… But core subjects are what actually clear interviews and build strong engineers. OS • DBMS • CN • OOPS These never go out of demand 🚀 If you’re serious about tech, don’t skip the fundamentals. 💬 Comment CORE and I’ll share a simple roadmap. [core subjects, computer science fundamentals, os dbms cn oops, software engineering basics, tech interviews, placement preparation, cs concepts] #softwareengineering #techcareers #codingjourney #interviewprep #csstudents
