About

I’m a Java Consultant working in the FinTech & Payments space, with hands-on experience across Java/J2EE, Spring, Spring Boot, Cloud, Microservices, REST APIs, and scalable backend systems. My journey into tech hasn’t been a straight line. I come from a non-technical background, faced a 3-year gap during my government exams prep and had to rebuild everything from scratch. But that phase taught me something powerful: anyone can break into IT with clarity, consistency, and the right roadmap. Over the years, I’ve: • Transitioned successfully into software development • Worked with global teams in FinTech & product engineering • Built cloud-ready, scalable backend systems • Improved system performance, reliability, and code quality • Earned certifications like AWS Solutions Architect & Google Cloud Architect Now, I’m using my journey to help others who feel stuck. Students confused between DSA, YouTube tutorials, paid bootcamps, and endless resources , I’ve been there. My goal is to make your transition faster, simpler, and 100% achievable without burning money on overpriced courses. My goal here on LinkedIn is to: • Share practical insights from real industry experience • Help students understand what actually matters when preparing for tech roles • Mentor people who are navigating setbacks, delays, or non-linear journeys • Build a community of learners aiming for strong tech careers • Offer affordable, high-clarity guidance through structured plans and 1:1 sessions If you're working toward an IT role and need clarity, direction, or mentorship, feel free to DM or check my mentoring services on Top mate. Let’s build your IT journey the smart way.
