Diverse, Seasoned SWE and Mentor. FAANG interview guidance.

As a seasoned Principal Software Engineer with over a decade of experience, I've honed my skills in systems design, architecting distributed, microservice-based architectures leveraging actor patterns and big data. Now pursuing an MS in Computer Science with a specialization in machine learning, I bring extensive experience in LeetCode, HackerRank, and other career assessments, along with expertise in resume crafting, salary negotiation tactics, behavioral questions, mock interviews, and freelance projects. Collaborating closely with FAANG companies and seasoned professionals, I've consistently boosted my salary by 10x in ten years and 3x in one year through continuous skill enhancement and interview technique refinement. My proficiency spans C#, .NET, and Angular, complemented by a deep understanding of Object-Oriented principles and functional, reactive programming. Across diverse industries such as Healthcare, Finance, Bio-Tech, Pharma, Legal, and Government, I've applied standard algorithms, data structures, design patterns, databases, and DevOps practices to deliver impactful solutions. Additionally, I'm passionate about mentorship, guiding others to achieve their career aspirations.

Charles is a great mentor and very thorough! We dove into Python, machine learning, artificial intelligence, data models and data parsing - while sharing insight on ways of looking at a problem from different angles. Seeing an example of an application using OpenAI was very cool! Got me up and running using Python and applied data models using JSON Schema. His expertise made leearning straightforward and enjoyable. From Python basics to understanding machine learning, his guidance was invaluable. His insights into data structuring and ethical considerations broadned my understanding. Charles's support fueled my growth!
