Hello! My name is Sandeep, and I am a staff software engineer based in London with several years of experience building large-scale backend and data systems at top tech companies like Meta. I specialise in Java, Python, SQL, distributed systems, and machine learning, and I love helping students truly understand how things work rather than just memorising solutions.
In our lessons, you can expect:
Clear explanations of concepts in algorithms, data structures, system design, and backend engineering, always adapted to your current level and goals.
Practical, hands-on exercises (LeetCode-style problems, system design scenarios, and real-world architecture discussions) so you learn by doing, not just by listening.
Structured guidance for interview preparation: from problem-solving strategies and time management to communication, mock interviews, and personalised feedback after each session.
I work regularly with technologies such as Java, Python, REST APIs, microservices, Kafka, distributed databases, and ML/AI systems, so I can connect theory directly to real industry use cases. Whether you are:
Preparing for coding or system design interviews
Strengthening your university CS fundamentals
Transitioning into backend/ML engineering
Or already an engineer wanting to level up to senior/staff roles
…I will design a learning plan tailored to you and your pace.
Most students benefit from starting with a short trial session where we:
Clarify your goals and timeline
Assess your current level with a light problem or discussion
Build a concrete roadmap for the next few weeks of study
If you are serious about improving your technical skills and want guidance from someone actively working in the industry, book a lesson or send a message and let’s get started.
