My Coding Journey:
- Back in 2021, during my first year of college, I started learning web development from Udemy.
- I began grinding on CodeChef, but soon realized competitive programming wasn’t for me, so I focused on DSA instead. I’ve solved around 1200 problems to date.
- After my second year, I started looking for internships and landed one at the University of South Carolina Aiken.
- During that internship, I published two research papers on dynamic programming. Together, they now have 5+ citations and 300+ reads.
- After my third year, I interned at IIT Guwahati, where I built a student-teacher management system for over 500 students.
- Before graduating, I worked as a founding engineer at a local startup.
- After that, I landed a full-stack internship at an amazing startup.
- After 5 months, I received a PPO from the startup and have been working there full-time since November 3, 2025.
- I bought a telescope with my very first salary.
Last month, I took my first flight with my mom to Varanasi.
- Yeah, that’s my journey in a nutshell. Being an electrical engineering student with multiple backlogs, it was quite hard to manage all of this—but I did it.

@OptimalHustler Thanks for the suggestion bro. Left leetcode also one year back. Might have to start from the very beginning again I think 🥲

@j3y3deka3 I'd say rethink the fact CP is not for you. Engineers are problem solvers and I think CP is just problem solving (obv). Give it enough time and you'll be great.

After watching @arpit_bhayani Sir’s DNS video, I got curious about how DNS works under the hood so I built my own DNS server from scratch using Golang!
Unlike typical DNS forwarders this server does not depend on google (8.8.8.8) it performs true iterative resolution just like a true DNS resolver.
Features:
1) True Recursive iterative Resolution: Instead of forwarding queries the resolver starts at the root servers and walks the hierarchy. (Root server -> TLD server -> Authoritative server -> Final Answer)
2) Glue Record & Sub-Resolution Handling: When a DNS server refers to another nameserver without providing its IP, this resolver i) Pause the main query ii) Resolves the nameserver hostname etc.
3) High Performance DNS Cache: Implemented using sync.Map, Thread safe, TTL Aware, Returns cached answers in less than 1 seconds.
4) Authoritative Overrides (Local DNS)
5) Hot-Safe Concurrency: This server handles thousands of concurrent DNS requests using goroutines. Used sync.RWMutex, sync,Map for thread safety.
Would love to hear everyone’s thoughts! This may not be perfect by any means, but I learned something really interesting.

@j3y3deka3 No, nothing that complex yet, a basic class based on a memory database.
Access is based on the primary key; put it all in a HashMap. nothing that complex yet.

@Itstheanurag That's interesting what r u using? B+ tree or lsm tree? I also built a lsm tree a few days ago. It works similar kind of Cassandra.
