About

Background, approach, and what to expect

I am a Frontend Engineer with 7 years of experience architecture-ing and building scalable web and mobile applications at leading technology companies. My core stack includes React, React Native, JavaScript, TypeScript, and GraphQL, alongside an active focus on building AI-powered applications, LLMs, and agentic workflows.

Beyond building systems, I have sat on both sides of the interview table. Having conducted numerous official interviews and rigorously mastered the loops of top-tier tech companies, I specialize in preparing engineers for the exact formats that break most candidates:

System Design (HLD & LLD): Designing resilient, scalable client-side architectures.

Machine Coding: Writing clean, modular, and extensible code under tight time constraints.

JS Problem Solving: Deep dives into core JavaScript, closures, event loops, and custom polyfills.

How I Can Help You Win Your Next Interview Knowing the tech is only half the battle; managing the clock is the other. The biggest mistake candidates make is letting a great signal spill over past the 60-minute mark. I will help you master the meta-game of interviewing:

Time Management & Pacing: Exact breakdowns of how many minutes to spend on gathering requirements, high-level design, deep dives, and bottlenecks so you never run out of time.

Communication Strategy: Exactly what to say, how to articulate your trade-offs, and when to pause for interviewer feedback.

Actionable Mock Interviews: Real-world scenarios designed to simulate high-pressure loops, followed by brutal, constructive feedback.

Let’s map out your preparation strategy and turn your technical gaps into strengths.
