Señors @ Scale host Neciu Dan sits down with Tyler Benfield, Staff Software Engineer at Prisma, to go deep on database performance. Tyler's path into databases started at Penske Racing, writing trackside software for NASCAR pit stops, and eventually led him into query optimization, connection pooling, and building Prisma Postgres from scratch. From the most common ORM anti-patterns to scaling Postgres on bare metal with memory snapshots, this is the database conversation most frontend developers never get.
Señors @ Scale host Neciu Dan sits down with Corbin Crutchley — lead maintainer of TanStack Form, Microsoft MVP, VP of Engineering, and author of a free book that teaches React, Angular, and Vue simultaneously — to dig into what it actually means to maintain a library that gets a million downloads a week. Corbin covers the origin of TanStack Form, why versioning is a social contract, what nearly made him quit open source, and the surprisingly non-technical path that got him into a VP role.
Señors @ Scale host Neciu Dan sits down with Andrey Sitnik — creator of PostCSS, AutoPrefixer, and Browserslist, and Lead Engineer at Evil Martians — to explore how one developer became responsible for 0.7% of all npm downloads.

Señors @ Scale host Neciu Dan sits down with Daniel Afonso — Senior Developer Advocate at PagerDuty, SolidJS DX team member, egghead instructor, and organizer of the JNation conference in Coimbra — to explore how a kid who taught himself to navigate the web before he could read became one of the most active voices in the developer community. Daniel shares his origin story, how writing about every hard problem he faced at work became the skill that launched his career, and the one hidden tip every developer should use when joining a new codebase.
Señors @ Scale host Neciu Dan sits down with Lucian Popovici — founder of Bridging Innovation and the free mentorship community Bridging Gaps, former Director at Deloitte Digital Romania where he scaled the team from 0 to 700, and veteran of Deutsche Bank and Ericsson — to talk about what actually happens when engineers become leaders, why the manager title is a trap for the ego-driven, and how AI is reshaping not just team sizes but entire industry models.
Señors @ Scale host Neciu Dan sits down with Anamari Fisher — engineering leader, coach, and O'Reilly author of 'Leveling Up as a Tech Lead' — to explore the first jump into leadership. Anamari shares how she went from software engineer to tech lead and product director, why accountability is the key differentiator from senior engineer, and how to scale your impact through soft skills that actually work in real teams.
Señors @ Scale host Neciu Dan sits down with Florian Rappl — author of 'The Art of Micro Frontends,' creator of the Piral framework, and Microsoft MVP — to explore how micro frontends are transforming how we build scalable web applications.

ES2025 is out, ES2026 is close. Here is the new feature of Javascript we can use today, what is coming next and how we can get our AI friends to use these new features
This made me take a good, hard look at my Astro blog and start optimizing: assets, headers, caching, CDN. Here is exactly what I did to fix it.
I spent three days building a custom ESLint rule and accidentally learned how JavaScript actually works. ESLint is just walking your code's syntax tree and running functions against each node. Once you see it, you can enforce any coding standard automatically instead of arguing about it in PR reviews.
Before you write another useEffect, ask one question: is this syncing with an external system? If not, there's a better way.
