    Learning is also a kind of earning. So, I learned Web analytics and completed 200+ projects on Fiverr and Upwork. Then I fell in love with Data Science and learned its all topics by heart along with a master degree in Data Science :) The future belongs to those who learn more and more skills so I believe that when we stop learning, we start dying. However, my existing skills along with a short description are given below. Web Analytics: Certified, experienced and best at web analytics using Matomo and Google Analytics. Web Development: PHP frameworks are my home turf and I have completed so many projects in Opencart, Codeigniter, Laravel, and WordPress. Please have a look at the portfolio to see the projects. Web scraping & crawling: Thanks to the Search Engine development project for which I crawled & scraped 1 million web documents :P so after that I always see myself doing scraping, crawling, and automation-related projects. For automation, I use selenium, beautiful soup, and Python. APIs development: As Python is in my blood so before data science, I used to work on APIs development and web scraping using Python. Big data: I have rich experience in the Hadoop eco-system using Apache Hadoop, Apache Hbase, Apache Nutch, Apache Hive, Apache Solr, etc. The detail is given below. ** Apache Hbase: How to store and retrieve data from Hbase and how to use it with Hadoop and Apache Nutch. ** Apache Nutch: How do search engines work? How to develop your own search engine using Apache Nutch as a crawler, Customization of Nutch at all phases, Tuning of Nutch for effective crawl, and a lot more. ** Apache Solr: How to use Solr for indexing purposes, How to use it in distributed mode, how to do indexing, how to analyze indexed data using different Solr clients. Matomo analytics: There was a time when I was the only Matomo related developer on Fiverr and Upwork. I have very rich experience in following tasks. ** Matomo Installation, configuration, and integration with the website. ** Matomo customization like custom dashboard development i.e., change look & feel different and you can claim that it is your custom product. ** Custom event tracking with/without Matomo tag manager ** Custom variables/dimensions, Goals, and conversions tracking. ** Conversion rate, custom reporting, and GeoIP-based correct location tracking. ** Expert to fetch tracking data through Matomo API to develop a custom dashboard or to display insights on another website.

    As a Master’s Degree holder in Computer Science, specializing in intelligent systems, I bring over six years of in-depth experience in system architecture, data analysis, and processing, with a keen focus on managing massive data flows. My expertise spans machine learning, database administration, data warehouse and lake design, NLP, web scraping, and DevOps, among others. I’ve had the privilege of contributing to cutting-edge machine learning research projects at Stanford University and collaborating remotely with Harvard professors. My work has focused on the design of bespoke machine learning models, generating interpretable explanations, and applying reinforcement learning. Additionally, I’ve developed optimization algorithms for diverse real-world applications, ranging from bail-out decisions and employee performance predictions to data mining and network modeling. My experience extends to managing large databases and complex data models, involving the complete redesign of databases containing sensitive information, developing ETL pipelines, and crafting Business Intelligence solutions. DevOps is a passion of mine. I thrive on creating scalable and elastic infrastructures using Docker, Kubernetes, graph databases, and message brokers to support sophisticated code and ML models. My enthusiasm extends to optimizing Python code, deploying TensorFlow models, designing micro-services, and implementing in-memory databases for high transaction volumes. Beyond technical capabilities, I excel in academic writing, project proposal creation, product development, and project management, underscoring my holistic approach to technology projects.
