Eduardo Aparicio Cardenes
Front-End Engineer, ADPList Top 100 Mentor 2025
In this episode of Señors @ Scale, host Neciu Dan sits down with Eduardo Aparicio Cardenes — Front-End Engineer and ADPList Top 100 Mentor — to unpack 15+ years of engineering lessons, the reality of promotions, and what it truly means to mentor and scale as a leader.
Main Takeaways from my conversation with Eduardo:
🧭 Mentorship is leverage.
Eduardo shows how guiding others multiplies your own growth, from sharpening communication to solving unfamiliar problems through someone else’s lens.
🔥 Curiosity, frustration, and even anger are motivators.
Channeling those emotions into learning or proving a point can spark breakthroughs in your engineering journey.
🏗 Promotions are perception + relationships.
It’s not just what you build, but how others see your impact — from your immediate team to your whole organization.
🧩 Divide and conquer your growth.
Eduardo encourages mentees to break down what they don’t know, turn blockers into learning paths, and scope problems realistically.
💬 Communication beats brilliance.
A good tech lead isn’t the smartest in the room — they’re the clearest communicator, making ideas and direction easy to follow.
🎯 Mock interviews matter.
Eduardo stresses role-swapping — becoming the interviewer is the fastest way to understand what companies really look for.
🚦 Burnout needs debugging too.
Apply engineering thinking: identify factors you can control vs can’t, then tackle them methodically.

Señors @ Scale host Neciu Dan sits down with Santosh Yadav, principal developer advocate at CodeRabbit and one of only around 80 GitHub Stars in the world. Santosh started hating C in 2004, fell for C# by 2008, and turned a year of open source contributions to Angular and NgRx into a stack of community titles — Google Developer Expert, GitHub Star, Nx champion, and Microsoft MVP. As a staff engineer at Celonis he led the move of 20-plus apps to module federation and drove Nx adoption across 30-plus teams when the product grew from four apps to thirty. From the year-long incremental migration off a single deployable unit, to why polyrepos can't give AI tools the context they need, to how Nx's affected graph and build caching tame a 20-million-line monorepo, to running code review for free for open source at CodeRabbit, this is the monorepo conversation grounded in someone who actually shipped one at scale.
Señors @ Scale host Dan Neciu sits down with Nicolas Beaussart-Hatchuel, staff engineer at Payfit and one of the maintainers of TanStack Router. Nicolas's path started with C macros to auto-generate his student paper headers and frontend learned by building phishing login pages for practice, took him through an iframe-based AngularJS-to-Angular 2 micro frontend migration at a web radio platform, into open source contributions across NX, ESLint, Vite and Hasura, and finally to maintaining one of the most ambitious routers in the React ecosystem. From why TanStack Router exists, to migrating Payfit's 300-route, 1.5-million-line codebase off React Router v5 using the strangler pattern, to collapsing 25 polyrepos and five different micro frontend strategies into a single modular monolith, this is the routing conversation most engineers never get.
Señors @ Scale host Neciu Dan sits down with Mark Erikson, maintainer of Redux and senior front-end engineer at Replay.io, where he works on a time-traveling debugger. Mark's path started with a 286 he got at eight years old, ran through a computer science degree, four years teaching English in China, embedded software at Northrop Grumman emulating legacy CPUs in old aircraft, and a chain of projects — GWT, jQuery, Backbone — that led him to React and Redux. From the @deprecated backlash that had people insulting him on the internet, to why the Redux core hasn't meaningfully changed since 2016, to what RTK Query actually solves, the underused listener middleware, building source maps into React's own build pipeline, and how Replay's recordings now hand debugging over to AI agents — this is the Redux conversation grounded in two decades of shipping software.
Señors @ Scale host Dan Neciu sits down with Dominik Dorfmeister — better known as TkDodo — the maintainer of TanStack Query and a software engineer at Sentry. Dominik's path started at a technical high school in Vienna, ran through JVM backend work in Java and Scala, and turned to frontend around the introduction of TypeScript. During the pandemic lockdowns in Austria he started answering questions in the TanStack Discord, got addicted to the instant gratification of helping people, and slowly turned that into a blog, a first code contribution six to eight months later, and eventually maintainership of TanStack Query. From tracked queries and the chaotic version-three-to-four rename, to the version-five mistake he still dreads, to ripping 28,000 lines of dead code out of Sentry with Knip and building Sentry's new design system, this is the open source maintenance conversation most developers never get to hear.
