Journey

Feb 9, 2026 - Present
Week 2: Stacks & LIFO Operations

Implementing stack data structure from scratch, solving parentheses matching problems, and building a text editor with undo/redo using dual-stack architecture. Target: 7 LeetCode problems + Mini Project.

In Progress
Feb 2-8, 2026
Week 1 Complete: Arrays & Fundamentals

Completed 16 array exercises covering traversal, manipulation, and sorting. Solved 7 LeetCode problems (two-pointer, prefix sum). Built Student Grade Manager with CRUD operations, validation, and statistics calculation.

About

CS undergraduate executing an 11-month FAANG preparation roadmap. Focused on systematic mastery of data structures, algorithms, and programming fundamentals through weekly projects and daily problem-solving.

Primary interest in data-focused roles: Data Science, ML Engineering, and Analytics Engineering - building models, analyzing datasets, and creating data pipelines. Also open to Software Engineering roles involving data systems, ML infrastructure, or developer tools.

Believe in understanding mechanics before optimization and learning through building. Interested in privacy-first architectures and systems that solve real problems.

Current Goal: Seeking Summer 2026 internship in Data Science, ML Engineering, Analytics Engineering, or Software Engineering at companies working on impactful data-driven products.

What I value:

  • — Understanding mechanics before optimization
  • — Building from scratch to expose complexity
  • — Consistent weekly progress over cramming
  • — Privacy-first, local-first architectures
