A Specialist is an expert who offers innovative solutions to complex business requirements, leveraging their in-depth knowledge of one or more technologies and extensive industry experience. Specialists excel in technology solution design and development, applying the right technology to various business scenarios across multiple projects. For instance, a specialist might recommend graphical visualizations with drill-down capabilities for business summary reports, advising on whether data aggregation should occur at the database level, backend application layer, or client side. They might also suggest the use of BI tools versus custom query-based reports and decide whether to prepare data aggregation beforehand or extract it in real-time from transactional databases.

While there are numerous areas in which one can specialize, here are a few examples:

Data Engineer

Data Engineers specialize in managing and supporting data and databases. Their role involves handling large datasets, data transformation, and migration, often loading data from traditional sources like CSV and Excel into databases. They may also extract data through web services and transfer it to local databases, aggregating it for report generation. Daily tasks include writing complex queries, functions, triggers, and connecting to remote databases. Proficiency in Python, Linux shell scripting, MongoDB, and optimizing data storage and query performance is crucial.

Test Automation Specialist

A Test Automation Specialist focuses on testing applications for various functionalities, employing technology-based testing and developing frameworks for automation. Common tools include Java with Selenium or Appium and TestNG for web and mobile app automation. Managing large-scale automation projects with thousands of test cases, addressing variations in user roles and device types, and running tests over extended periods (e.g., 8-10 hours) requires significant expertise. Efficiently reporting and managing regression defects are also key aspects of this specialty.

I have extensive experience across these areas and am eager to share my knowledge with those ready to advance to the next level. This course can be tailored as a one-to-one series, accommodating the varying experience levels of each individual.
