Lessons
Developer Relations engineer who spends most of his time on developer tooling, AI infrastructure and open source. Built PlacePrep after watching too many capable students get filtered out by rounds they were never taught to prepare for.

Courses
- 25 lessons
AI Inference Engineering
How trained models actually get served in production — quantization, batching, KV caching, speculative decoding, GPU internals, benchmarking and the hardware underneath.
- 30 lessons
Machine Learning
What machine learning actually is, taught from zero with no hand-waving — from vectors, probability and Bayes' theorem, through every major classical model, to neural networks and the real tools (NumPy, pandas, scikit-learn, PyTorch) used to build them.
- 44 lessons
Context Engineering
How LLMs actually read context, from tokenization and attention math up through retrieval, memory, agents, rigorous evaluation, and the full production tech stack — with C++ hands-on labs throughout, plus a deep Context Designing module for building it all for real.
- 26 lessons
C++ Programming Basics
Start from zero and build a real mental model of how C++ works. Written around the mistakes people actually make, not just the syntax.
- 51 lessons
Data Structures & Algorithms
Start from complexity analysis and work up to graphs and dynamic programming. Built for coding rounds and technical interviews.
- 25 lessons
System Design
Design scalable systems from first principles — load balancing, caching, databases, distributed systems patterns and real-world case studies.
- 44 lessons
SQL & Databases
How databases actually work, taught from absolute zero with the math behind every idea — SQL from scratch, relational theory, indexing, transactions, and a full guided tour of PostgreSQL, MySQL and NoSQL so you know exactly which database to reach for and when.
- 31 lessons
Web Scraping
From raw HTTP requests and HTML parsing to Selenium, Playwright, Puppeteer, CAPTCHAs, production scraping and modern AI-driven tools like Firecrawl, Apify and crawl4ai — rooted in the fundamentals, one module at a time.
- 29 lessons
Docker & Kubernetes
Containers and orchestration explained from first principles — what problem they actually solve, how Docker works under the hood, and how Kubernetes takes container apps to production at scale.
- 31 lessons
Computer Networks
How computers actually talk to each other, built up from first principles: wires and radio waves, addresses, routing, reliability, and the web itself. Every idea is explained with a simple picture first, then the real math behind it.
- 41 lessons
Compiler Design
How a pile of text you type becomes a running program, explained from absolute zero: hand-drawn pictures first, then the real math and C++ underneath every phase — lexing, parsing, semantic analysis, runtime environments, intermediate code, optimization, and a full working compiler you build yourself.
- 42 lessons
Operating Systems
How your computer actually manages itself, built up from absolute zero: system calls, processes, threads, IPC, concurrency and synchronization, deadlock, CPU and I/O scheduling, memory management, virtual memory, and file systems — with the real math behind every idea, ending with a hands-on module where you build a real bootable kernel in C++.
- 37 lessons
Computer Organization & Architecture
How a computer actually works underneath every program you've ever run, built up from a single switch to a full working machine: binary and logic gates, the ALU and datapath, the control unit, instruction pipelining, the memory hierarchy, how devices talk to the CPU, and a full trace from pressing the power button to a running program. Every idea starts with a five-year-old's picture, then the real math and hardware behind it.
- 52 lessons
Database Management Systems
How your data actually gets stored, organized, queried and kept safe, built up from absolute zero: data model history, the ER model, the relational model, relational algebra and calculus, SQL in depth (including window functions and CTEs), integrity constraints and normalization, file organization and indexing with B and B+ trees, transactions with concurrency control (isolation levels, MVCC, crash recovery), and query optimization and distributed databases. Every idea starts with a five-year-old's picture, then the real math behind it.
- 33 lessons
Local to Production: Scaling Systems
How a small app on your laptop turns into a system serving millions of people — servers, databases, caching, the cloud, microservices and background jobs, explained from absolute zero with the math behind every decision and a clear rule for exactly when to add each piece.
