Hello everyone! This week I began my daily learning journey β diving into System Design concepts (via the roadmap.sh System Design Roadmap) and solving DSA challenges on LeetCode.
β 7 days straight of showing up. Here are the highlights:
π System Design Concepts Covered
- Latency vs Throughput β Learned how speed (latency) and volume (throughput) trade off in system performance.
- Consistency Patterns β Strong, Weak, and Eventual β and where each makes sense (finance vs gaming vs social media).
- Availability Patterns β Redundancy, Replication, Load Balancing, Circuit Breakers, etc.
- Failover β Active-passive vs active-active setups, and why resilience always adds complexity.
π‘ Biggest Insight: System Design is about trade-offs, not absolutes. You never get high availability, high consistency, and high performance all at once.
π» DSA Problems Tackled
- Regular Expression Matching (hard) β Recursive approach stretched my thinking.
- Integer β Roman Conversions β Dictionary lookups + loops made the logic clean.
- Longest Common Prefix β Sorting trick was an elegant win.
π‘ Biggest Insight: For DSA, sometimes brute force teaches you the problem space β but the best solutions come from reframing (like sorting or recursion).
π Week 1 Reflections
- Showed up daily despite challenges (some problems took 2β3 hours).
- Learned to balance deep dives (like regex recursion) with practical clarity (like Roman numeral conversions).
- Seeing patterns emerge between System Design and DSA: both are about trade-offs and structured problem solving.
π Whatβs Next (Week 2 Goals)
- Push into more advanced system design topics (e.g., gRPC, DB sharding, caching strategies).
- Continue solving medium/hard LeetCode problems, but improve on timeboxing solutions.
- Start sharing shorter code insights to make posts even more practical for readers.
π€ Letβs Connect!
Thatβs Week 1 in the books π.
If youβve been following along, Iβd love to hear:
- Which System Design trade-off do you find most challenging in real projects?
- Whatβs your DSA strategy β brute force first or optimal-first thinking?
- Or just drop a π‘ to celebrate learning and consistency!
Your engagement helps me keep momentum, and Iβd love to make Week 2 even better β for me and for everyone reading π.
