I'm currently working as a Software Engineer - Level 3 at Chaldal. I completed my undergraduate degree in Computer Science and Engineering from BUET in 2023. I have over 5 years of experience doing competitive programming and working on various projects and more than 1 year of professional experience.

• 🧩 I enjoy solving complex algorithmic problems. During my undergraduate years, I participated in various programming contests and hackathons. I had the honor of representing my country in the 45th ICPC World Finals in Dhaka, Bangladesh, and the 47th ICPC World Finals in Luxor, Egypt.
• 🏆 I am rated Master in Codeforces.
• 🔬 I have previously worked on theoretical computer science research to solve the Parameterized String Matching with Mismatch Tolerance problem.
• 🛠️ I am currently exploring Distributed Systems and System Design.
• 🌟 I love designing and building complex systems and feel fortunate to witness the advancement of technologies.

Here’s some things I’ve learned from my experience over the years:

• Murphy's Law: "Anything that can go wrong, will go wrong."
• Ensuring data consistency across different microservices can be complex. Each piece of data should have a single source of truth, and other services must be able to adapt and stay in sync with that source. Distributed Transactions are your friend.
• In distributed systems, network failures are inevitable. Always design for resiliency and plan for retries and fallbacks.
• Allocate sufficient time to plan the entire design before diving into coding. Designing for unhappy paths is often more challenging than designing for happy paths.
• Even a rare bug with a probability of 0.01% can occur more frequently than expected with a large number of users. For example, with 10,000 daily users, you might encounter such a bug approximately everyday.
• As the system scales, performance bottlenecks can appear. Regular profiling can help find and fix these issues early.
