How AI Changed My Work
Since its launch, generative AI has fundamentally changed my work by automating the time-consuming and routine aspects of data engineering, such as writing boilerplate code, generating documentation, and debugging complex queries. This automation has shifted my focus away from manual implementation and toward higher-value strategic tasks, including designing more sophisticated data architectures and critically evaluating the insights produced by AI-driven systems.

AI Job Automation
AI Job Automation Reality Check 🤖💼
After attending dozens of job fairs and speaking with hundreds of recruiters across analytics, IT, and engineering roles, the transformation is undeniable 📊🔧. What I'm hearing consistently is that 23.5% of companies have already replaced workers with AI tools like ChatGPT1, and 49% of companies using AI say it has directly replaced human workers1. Recruiters are telling me that 300 million jobs globally could be automated23, with 30% of current U.S. jobs potentially automated by 20301. The most shocking revelation? Entry-level positions are especially vulnerable, with nearly 50 million U.S. jobs at risk

AI and Career Formation
This job fair held on May 13, 2025, was the largest job fair in Central Massachusetts this year. It featured over 100 employers from a wide range of industries—including healthcare, education, construction, finance, and public service—seeking candidates to fill open positions. The event provided job seekers with opportunities to connect directly with hiring managers, explore new career paths, and learn about current labor market trends.
Robot Jobs
Artificial intelligence is rapidly transforming the job market, both creating new opportunities and leading to significant job displacement. According to the World Economic Forum’s 2025 Future of Jobs Report, 40% of employers expect to reduce their workforce where AI can automate tasks, and nearly 50 million U.S. jobs could be affected in the coming years27. Entry-level and routine white-collar roles—such as HR associates, analysts, and administrative staff—are especially at risk, with companies increasingly relying on AI for efficiency and scalability
Continuous Learning
AI’s impact is not limited to job loss; it is also reshaping the skills required in the workforce. Many existing jobs are being redefined, with a greater emphasis on digital literacy, critical thinking, and the ability to work alongside AI systems9. While AI is expected to displace millions of jobs globally, it is also projected to create millions of new roles, particularly in technology, data analysis, and human-machine collaboration89. This shift underscores the urgent need for workers to pursue upskilling and retraining to remain competitive in an AI-driven economy

Why Data Engineers Should Think Like Product Builders
In data engineering, the difference between "good enough" and game-changing often comes down to treating your work like a product, not just a pipeline.

Networking & Business Connections
Gabriel - Veteran Entrepreneur
I gave Sam very vague requirements about a data analysis project, and he worked with me to define the scope while iterating to ensure the final product met my needs. He delivered valuable insights under budget and discovered patterns in the data I never expected. His expertise perfectly complemented my industry knowledge. I strongly recommend Sam for any data-related task.
Gavin - No-Code Automation Expert
Working directly with Sam has been a pleasure, especially on technical projects. He always keeps the overarching goal in mind, which creates flexibility and makes it easier to achieve wins along the way. His coordination between different team members ensured smooth project execution.
Faizan - Graphic Artist
Sam and I worked together for eight months on Upwork. He has been running a teaching business for 18 months, specializing in data science. Beyond being easy to work with, he excels in project management, even under tight deadlines and last-minute changes. He always provided clear instructions and checked my workload before assigning projects, ensuring a balanced workflow. His talent, professionalism, and attitude speak volumes!
Data is connectedness — and so are we
Matt - Fullstack Web Engineer
I met Sam at the Austin Indie Hackers meetup, where he stood out as someone who values hands-on experience over theory. Whether it was copywriting or engaging an audience on social media, Sam’s practical advice raised the bar for our group. His insights on promoting projects elevated my thinking—he's an asset to any team looking to grow
Cornelius – Senior Software Engineer
Sam has been co-hosting virtual entrepreneurship and innovation meetings since the pandemic began, playing an integral role in maintaining that community. He listens to others' ideas, provides valuable advice, and helps connect people to the skills and expertise they need. He is dedicated to growth and willing to step outside his comfort zone
Kelsie – UX Design & Product Manager
Sam and I worked on improving data visualization within our firm. He took initiative by creating a survey to better understand the tools others were using, ensuring that design decisions aligned with user needs. He also helped develop an R library for internal use. Sam is proactive, always seeking to improve work experiences for others
Stephen, Actuarial Analyst, Health Insurance
"Sam's course was great. I took Exam PA in June 2021 and got my first 10 on an exam. I used only Sam's course and practice exams to study."
Sean, Actuarial Associate
"I almost exclusively used ExamPA.net for studying, crammed it all in two days, and still got an 8!"
Sam, Actuarial Analyst
"I recently took and passed the June 2021 PA sitting. I got a 9 with your help—the highest exam score I've ever had, and on my first attempt! Loved your prep. Thank you! Don't suppose I can convince you to make a guide for the EA exams next?"
Predictive Analytics Lessons
The SOA modules do not prepare you for this exam. Sam’s course helped me pass even though I started it late—I only purchased it on October 28th and sat for the exam on December 7th. I passed with a 7. The course tells you what you need to know and HOW to study effectively. The way he teaches, writes, and explains things makes it easy to understand."
A great learning tool and life saver!
"Buy 👏 this 👏 course 👏 This course is the reason I passed in December. I wouldn't have been able to prepare at all on my own, and I wouldn’t have even been willing to TRY to sit for the December exam if it weren’t for this product. I passed after only studying for 2.5 months because Sam is really THAT GOOD. Passed Dec 2019."
Delegate the Code. Focus on Strategy.
I handle the models, pipelines, and messy data — so you can focus on making smart business moves.
With experience at Expedia Group (handling global tax data pipelines), and actuarial analytics at Milliman and Willis Towers Watson, I’ve worked across industries. Now as the founder of Predictive Insights AI, I help startups and small businesses turn raw data into real results.
From ETL & EDA workflows to automated predictions and dashboards, I deliver insights without the noise — so you don’t have to write a single line of code.
Want your business to think like a data scientist (without becoming one)?
Let’s make that happen.
