Independent software, built to be understood
ClusterMicro Technologies is a small, independent software studio in Bengaluru, India. We build research and learning tools that take something complicated — the stock market, a Java certification exam — and make it legible, one clear answer at a time.
One engineer, two decades of enterprise software
ClusterMicro was founded by Arup Jyoti Basu, a software engineer and project manager whose career spans large multinational technology organisations, with roles across companies including SAIL, Siemens, GE, EMC, Kronos, Symantec and Capgemini. That background is in designing and shipping real systems under real constraints — and it is the same discipline applied to everything published here.
He holds the Oracle Certified Associate (OCA), PMP and Scrum certifications. StockLearn, JavaLearn and JavaOCP are not a content farm or a reseller of someone’s data — they are hand-built products, written and maintained daily by the person behind them.
Three products, one principle — explain everything
Different subjects, same conviction: a tool should teach you why, not just tell you what.
StockLearn
A technical research platform that scans about 2,000 NSE stocks, mutual funds and ETFs every evening and reduces each to one plain-English verdict — bullish, caution or weak — with the reasoning shown, never hidden. Nifty 50 is free, every day.
stocklearn.clustermicro.com →JavaLearn
Practice for the Oracle Certified Associate (OCA) Java exam — a large bank of exam-style questions with worked, explained answers, built for people preparing to certify rather than just to memorise.
javalearn.clustermicro.com →JavaOCP
Practice for the Oracle Certified Professional (OCP 21) Java exam — thousands of reviewed questions with detailed, code-traced explanations for the current professional certification.
javaocp.clustermicro.com →Research and education — not advice
Everything ClusterMicro publishes about markets is research and education, and we are deliberate about that line. StockLearn explains the method behind every verdict — what Stage Analysis is, how RSI actually behaves in a real uptrend, why volume changes what a move means — because a signal you don’t understand is worth nothing. Our market guides exist for exactly that reason, and are free to read whether or not you ever use the scanner.
ClusterMicro Technologies is not a SEBI-registered investment adviser, and nothing here is a buy or sell recommendation. The verdicts are automated technical indicators, not calls. Markets carry risk, and the responsibility for any decision is yours. We would rather be honest and useful than confident and wrong — that principle is the whole reason these tools exist.
