Digest #44: December 2025
This month at Mad Devs, we look at the foundations that keep products stable as they grow. From the tech stacks behind industry giants to clear business requirements and Web3 strategy, December's digest connects architecture, planning, and innovation with practical tools and concepts.
Foundation in focus
This month's content section covers three big questions: what powers leading products, how to write business requirements that actually guide delivery, and what it really takes to build a successful Web3 product.
Tech Stack of Prominent Companies: What Are Industry Giants Using to Power Their Applications?
Our article explores the technologies that sit behind well-known products and services. It explains what a tech stack is, how leading companies combine languages, frameworks, and cloud platforms, and why your stack choice should reflect your use case rather than trends.
➡️ We also shared a short LinkedIn overview with key takeaways.
Writing Business Requirements for a Software Product: Best Practices and Templates
Clear business requirements keep projects aligned and reduce the gap between stakeholders and engineering teams. This guide explains what a BRD should include, how to describe business goals and constraints, and how to make requirements specific enough to guide real work without blocking collaboration.
➡️ You can find a concise LinkedIn version with the main structure and tips.
How to Build a Successful Web3 Product?
Web3 can mean everything and nothing: crypto, dApps, NFTs, DAOs, wallets, chains. This article walks through what Web3 is, which technologies enable it, which real-world examples already work today, and what to consider if you want to build a Web3 product that brings value instead of speculation.
➡️ We revisited the topic on LinkedIn with a focused summary for product and tech leaders.
Latest entry in Tech Journal
This article shows how an AI agent pipeline can speed up early-stage project estimates while staying close to how real delivery teams work. The pipeline mirrors roles like Product Owner, System Architect, Tech Lead, and Delivery Manager, passing context from one stage to the next and producing structured outputs such as user stories, architecture decisions, effort estimates, and staffing plans.
