    React at Scale with Mateusz Albuquerque
    2025/08/18
    In this episode of Señors @ Scale, Staff Frontend Engineer Mateusz Albuquerque joins Dan to talk all things React, rendering, and real-world performance at scale.They dive into React scheduling and fibers, why rendering strategies always “depend,” and how to make performance decisions when millions of users are at stake. Mateusz shares war stories about dropdowns with 16,000 options, migrating a stable React app to SSR (and regretting it), and what happens when browsers you’ve never heard of load your app in production.They also unpack how feature flags and ring deployments help ship safely, why junior devs struggle when they learn frameworks before fundamentals, and how mentorship + RFC-driven development can keep teams moving in the right direction.🎯 Whether you’re debugging hydration issues, experimenting with performance APIs, or mentoring new frontend engineers, this one is full of sharp lessons from the trenches of large-scale React.*Chapters*00:00 Introduction to Mateusz Albuquerque04:19 The Journey to Programming06:57 Diving into Frontend Development09:33 Understanding React Scheduling12:21 Rendering Strategies in React15:01 Web Performance Challenges and Solutions17:30 Techniques for Optimizing Performance20:01 Common Challenges for New Developers32:13 The Importance of Foundational Knowledge33:56 The Value of RFC-Driven Development35:42 Proud Achievements in Software Development39:57 Challenges and Bugs in Large Scale Applications46:11 Best Practices for Frontend Development49:40 Recommended Reading for Developers54:22 Personal Interests and Relaxation TechniquesFollow & Subscribe:📸 Instagram: [ / senorsatscale ]( / senorsatscale )📸 Instagram: [ / neciudev ]( / neciudev )🎙 Podcast URL: [https://neciudan.dev/senors-at-scale](https://neciudan.dev/senors-at-scale)📬 Newsletter: [https://neciudan.dev/subscribe](https://neciudan.dev/subscribe)💼 LinkedIn: [ / neciudan ]( / neciudan )💼 LinkedIn: [ / se%c3%b1ors-scale ]( / se%c3%b1ors-scale )Keywords:Mateusz Albuquerque, React, frontend development, web performance, programming challenges, mentorship, feature flags, deployment strategies, tech conferences, performance optimizationDon’t forget to like, comment, and subscribe for more engineering stories from the front lines.

  • Refactoring at Scale with Jose Calderon

    Refactoring at Scale with Jose Calderon
    2025/08/11

    In this engaging conversation, Jose Calderon, a lead software engineer at JP Morgan Chase, shares his journey into software engineering, his passion for Java and the Spring ecosystem, and the importance of documentation and decision-making in software architecture.


    He discusses the evolving role of AI in coding, offers tips for learning Java, and emphasizes the significance of mentoring future engineers.


    The conversation also touches on crafting engaging conference talks, testing strategies for enterprise software, and the balance between refactoring and rewriting code. Jose concludes with book recommendations and insights into the gaming world as a form of relaxation.


    Takeaways


    • Jose's journey into software engineering began with a passion for fixing computers and playing games.
    • Java's ecosystem is robust, with a strong community and rapid evolution.
    • Documentation of architectural decisions is crucial for future reference and understanding.
    • AI tools can enhance productivity but should not replace fundamental coding skills.
    • Unit tests should serve as documentation for code behavior.
    • The choice between refactoring and rewriting code depends on the stability and control of the existing system.
    • Chaos engineering helps teams prepare for unexpected failures in production environments.
    • Mentoring future engineers is essential for fostering a strong tech community.
    • Crafting engaging conference talks involves storytelling and relatable analogies.
    • Gaming can serve as a form of relaxation and mental recharge for developers.


    Sound Bites


    "You can build whatever you want and play around."

    "The world is your oyster with Java."

    "You can simplify and still be effective."

  • Pragmatism at Scale with Tudor Barbu

    Pragmatism at Scale with Tudor Barbu
    2025/08/04

    🎙️ In this episode of Señors @ Scale, Principal Engineer Tudor Barbu (ex-Personio, Skyscanner) shares two decades of software engineering lessons — from hacking on cassette-based machines to leading platform efforts in modern frontend teams.


    We talk debugging horror stories, the evolution of tech roles post-pandemic, and the shift from chasing technical perfection to delivering user value. Tudor breaks down what it means to be a pragmatic engineer, how he interviews for adaptability, and why ownership (not just code) drives results.


    Whether you're mentoring juniors, scaling architecture, or just tired of reading octal bugs — this one’s for you.
