About Ayush Kumar

If you\'re trying to break into Data Analytics or crack SQL interviews — you\'re in the right place.I\'m Ayush, a Data analyst with 4+ years of experience in SQL, Python, PySpark, and Power BI. I\'ve worked with companies like TCS and Nagarro, building ETL pipelines, optimizing data workflows, and solving real-world business problems with data.But my real passion? Helping YOU get there faster.I started mentoring because I know how overwhelming it feels to learn SQL from scratch, apply for jobs, and not know if you\'re even preparing the right way. I\'ve been there. So I built a system that actually works.Here\'s what I help with:→ 1:1 SQL Mentorship (Joins, CTEs, Window Functions, Interview Prep)→ Real-world SQL case studies and projects→ Resume & portfolio reviews for Data Analyst roles→ Interview strategy and mock SQL roundsResults so far:→ Trained multiple learners from zero to interview-ready→ Helped candidates crack SQL rounds at top companies→ Created \"The Data Engineer\'s Playbook\" — a practical guide for aspiring data professionalsIf you\'re serious about cracking your next SQL interview or switching to a Data Analyst role — let\'s work together.
