Raman Trehan
LeetCode tutor
US$22.00 /15 minI can help you with the following: -> Design/Implement large scale distributed systems and dive deep into concurrency, communication, availability, scalability, etc. Rather than just knowing Kafka, Redis and Cassandra, it's important to understand what system features you need to put these building blocks together. -> Data structures and algorithms (Leetcode, Topcoder, etc), low level system design (object oriented programming, design patterns) and high level system design (distributed systems, etc). -> Well structured plan and mentorship (short/long term) for interview preparation, conduct mock interviews for software engineers and senior software engineers. I have extensive experience in tech interviews, as a candidate as well as being part of panel team. -> Mentoring for growing into senior software engineering roles. -> Project building (end to end). -> Pivoting from another domain/career into software engineering. -> Other tech topics that you might be interested in (AWS, Kafka, Redis, Databases, etc). About me: I write software and work with distributed systems day-in and day-out. I have worked at Qualcomm in the area of smart vehicles. I have been involved with startups like Dailyhunt to build backend systems end to end; which could scale to the order of 50k+ requests a second. Feel free to block something on my calendar: https://calendly.com/ramantrehan/30min. Kindly ping me on chat when you do so.

How long does it take to learn LeetCode?
The time it takes to learn LeetCode depends greatly on several factors, including your prior experience, the complexity of the language or tech stack, and how much time you dedicate to learning. Here’s a general framework to help you set realistic expectations:
- Beginner level: If you are starting from scratch, getting comfortable with the basics of LeetCode typically takes about 3 to 6 months. During this period, you'll learn the fundamental concepts and begin applying them in simple projects.
- Intermediate level: Advancing to an intermediate level can take an additional 6 to 12 months. At this stage, you should be working on more complex projects and deepening your understanding of LeetCode’s more advanced features and best practices.
- Advanced level: Achieving proficiency or an advanced level of skill in LeetCode generally requires at least 2 years of consistent practice and learning. This includes mastering sophisticated aspects of LeetCode, contributing to major projects, and possibly specializing in specific areas within LeetCode.

How does personalized LeetCode mentoring differ from traditional classroom learning?
Personalized LeetCode mentoring through Codementor offers a unique and effective learning approach compared to traditional classroom learning, particularly in these key aspects:
- Customized content: Personalized mentoring adapts the learning material and pace specifically to your needs and skill level. This means the sessions can focus on areas where you need the most help or interest, unlike classroom settings which follow a fixed curriculum for all students.
- One-on-one attention: With personalized mentoring, you receive the undivided attention of the tutor. This allows for immediate feedback and detailed explanations, ensuring that no questions are left unanswered, and concepts are fully understood.
- Flexible scheduling: Personalized mentoring is arranged around your schedule, providing the flexibility to learn at times that are most convenient for you. This is often not possible in traditional classroom settings, which operate on a fixed schedule.
- Pace of learning: In personalized mentoring, the pace can be adjusted according to how quickly or slowly you grasp new concepts. This custom pacing can significantly enhance the learning experience, as opposed to a classroom environment where the pace is set and may not align with every student’s learning speed.
- Practical, hands-on learning: Mentors can provide more practical, hands-on learning experiences tailored to real-world applications. This direct application of skills is often more limited in classroom settings due to the general nature of the curriculum and the number of students involved.
Personalized mentoring thus provides a more tailored, flexible, and intensive learning experience, making it ideal for those who seek a focused and practical approach to mastering LeetCode.
