7 Newsletter or Influencer Worth Subscribing in 2025

If you're looking to stay updated and inspired in software development or data engineering, here are seven newsletters and influencers worth following in 2025 (I personally curated this list which help me to stay up-to-date with the latest tech):

• ByteByteGo (LinkedIn & newsletter)
• stevencodes.swe (Instagram)
• arjay_the_dev (Instagram)
• Quant Science/PyQuant News (Instagram & newsletter)
• eczachly (Instagram & Youtube & newsletter)
• Educative (newsletter & online courses)
• Medium Daily Digest (newsletter)

ByteByteGo is my top recommended newsletter, created by Alex Xu. He focuses on system design, backend engineering, and technical interview preparation. The newsletter and the posts on LinkedIn features clear, animated graphics that make complex concepts easy to understand. Alex consistently delivers concise updates every 2–3 days, covering a wide range of relevant topics.

stevencodes.swe: Steven is a software engineer and Instagram influencer known for practical coding tips. His interactive backend triage quiz on scenarios—such as handling call alerts—challenge us to think through solutions. He reviews each possible answer, explaining why some are incorrect and highlighting the best approach. Again, his graphics and flow diagrams are perfect for visualizing complex system concepts.

arjay_the_dev: Arjay is a Software Engineer, Educator, and Tech Influencer who shares practical system design content for engineers. He explains how different architectural decisions impact scalability and performance, making complex topics accessible. Plus, his instagram reels often feature his cat in the background (probably intentionally), adding a fun and memorable touch to his educational content.

Quant Science/PyQuant News: Curated by Jason Strimpel, this newsletter has immense resources for algorithmic trading, quant finance, and practical Python tips. Jason consistently delivers insightful content, sharing real-world applications and trends in data science. His posts are concise, actionable, and ideal for anyone interested in quantitative analysis or finance technology.

Data with Zach: Zach is a software engineering influencer who shares practical insights on Instagram, YouTube, and through his newsletter. His YouTube videos are especially helpful, breaking down complex concepts in clear, 15–20 minute segments. I’m currently exploring his free bootcamp on dataexpert.io and may write a review once I complete the course.

Educative provides a some free newsletter articles and a wide range of interactive courses covering coding interview prep, system design, and modern software engineering topics (including Python and other tech stacks). Their hands-on, project-based approach makes learning practical and engaging. I relied heavily on Educative during my first two years as a software engineer— their comprehensive syllabus covers everything from fundamentals to advanced concepts. They frequently offer discounts, so keep an eye out for special deals.

Medium Daily Digest: subscribe to receive a daily email from Medium featuring top articles on software development, data engineering, and tech trends. The more you engage with specific topics, the more personalized your recommendations become, allowing you to discover content tailored to your interests. I enjoy reading a variety of writers on Medium, not only in tech but also in personal development and other areas.
