About

A focused, system-first approach to building modern software.

Computer Science Student

I’m a Computer Science student focused on building modern full‑stack products and practical AI systems — with a growing obsession for backend architecture and system design.

I care about clean engineering, predictable performance, and systems that scale: caching, queues, data modeling, and reliable deployments.

2023

Started CS + shipping projects

Focused on fundamentals, JavaScript, and building end‑to‑end apps.

2024

Backend + databases

REST, auth, MongoDB/SQL, Redis, and production patterns.

2025

AI engineering

LLM applications, RAG, embeddings, and agentic workflows.

2026

System design depth

Scalability, consistency tradeoffs, and designing for reliability.

Problem Solving Journey

Sharpening fundamentals through DSA, competitive programming, and consistent practice — optimizing for clarity, correctness, and speed.

Mindset

I optimize for fundamentals: clean invariants, edge-case discipline, and performance intuition. The goal isn’t just passing — it’s building an engineering brain.

System Design

Architecture-first thinking: tradeoffs, bottlenecks, and scalable patterns.

Principles

Consistency vs availability tradeoffs
Backpressure, queues, and failure domains
Caching strategy: correctness → performance
Observability: logs, metrics, traces
