👋 About Me

I am a C++ developer and competitive programmer focused on Data Structures, Algorithms, and system-level problem solving. I am intentionally preparing for MAANG / top product engineering roles by combining algorithmic rigor, modern C++ practices, and production-grade workflows.

My work emphasizes correctness, performance, readability, testing, and automation—the same standards expected in large-scale engineering teams.

🧠 Core Technical Strengths

🔹 Modern C++ (17 / 20)

• std::optional, std::variant, Concepts, structured bindings
• STL-heavy, idiomatic, cache-aware implementations
• RAII, smart pointers, move semantics, lifetime safety
• Low-level performance analysis and optimization

🔹 Data Structures & Algorithms

• Arrays, Strings, Trees, Graphs, Heaps
• Dynamic Programming (memoization → tabulation → optimization)
• Graph Algorithms: BFS, DFS, Dijkstra, MST, Topological Sort
• Advanced Structures: Segment Tree, Fenwick Tree, DSU
• Number Theory, Bit Manipulation

🛠 Tools & Engineering Stack

• Languages: C++ (17/20), C, Python
• Build & Debug: CMake, GDB
• CI/CD: GitHub Actions
• Version Control: Git, GitHub
• Editors & OS: VS Code, Linux
• Concepts: OOP, Memory Management, Systems Thinking

🗺️ Engineering Roadmap (Industry-Aligned)

Phase 1: Algorithmic Foundations

• Competitive programming (Codeforces, LeetCode, CodeChef)
• Strong reusable DSA template library
• Time and space complexity discipline

Phase 2: Systems & Low-Level Engineering

• Memory layout and performance
• Concurrency fundamentals
• OS and networking basics
• Debugging, profiling, and tooling

Phase 3: Production-Grade Projects

• Modular C++ architecture
• Unit testing (GoogleTest)
• CI pipelines and automation
• Clean code and formatting standards
