Hi, I’m Rahul 👋 I’m a Senior Backend Engineer / SDE3 at JPMorgan Chase with 8+ years of software engineering experience, and I’ve previously worked at Oracle and Mindtree. My core expertise lies in Backend Engineering, Java, Spring Boot, Microservices, System Design, Distributed Systems, Cloud, and Platform Engineering. Over the years, I’ve worked on large-scale production systems involving: - High-scale backend services - CI/CD platforms - Kubernetes and cloud infrastructure - Distributed systems - Developer tooling and platform engineering How I can help on Topmate 🎯 Software Engineering Interview Preparation 💻 Java / Spring Boot / Backend Interviews 🏗️ System Design — HLD & LLD 🧠 DSA & Problem-Solving Strategy 📄 Resume Review & Profile Optimization 🚀 Career Guidance & Job-Switch Strategy 🎤 Technical Mock Interviews 🧭 1:1 Backend Engineering Mentorship If you’re preparing for an SDE, SDE2, or SDE3 interview, planning a move from a service-based company to a product company, strengthening your backend engineering skills, or preparing for System Design interviews, I can help you build a practical and focused roadmap. I believe in specific, actionable guidance rather than generic advice. My goal is to understand where you are today, identify the gaps, and help you decide exactly what to work on next. I also write technical content on Java, DSA, Low-Level Design, System Design, Cloud-Native Engineering, and AI Engineering through my engineering knowledge base and newsletter. https://thescalablestack.substack.com/ Tech Stack Java • Go • Spring Boot • Microservices • REST APIs • System Design • LLD • Distributed Systems • AWS • Docker • Kubernetes • Redis • CI/CD • Jenkins • DSA If you have a specific problem, interview goal, career question, or technical roadmap in mind, book a session and let’s work through it together. 🚀
