Bridging the Gap Between
Learning & Landing the Job
Hi, I am Jonathan, a Senior Data Analyst and Adjunct Professor passionate about helping professionals break into the most in-demand tech careers of our time.
With over 6 years of hands-on experience in data analytics, cloud architecture, and data engineering, I have seen firsthand what it takes to succeed in these fields. I have also seen how many talented people struggle to break in, not because they lack potential, but because they lack the right guidance.
That is why I started coaching. I combine my 4 AWS certifications, real-world project experience, and teaching background to give you a coaching experience that is both technically rigorous and practically focused on getting you hired.
