Frontend Architecture at Scale – With Faris Aziz

Key Takeaways from our conversation with Faris Aziz

Faris Aziz

Staff Front-End Engineer at Small PDF, Co-Founder of ZurichJS

In this episode of Señors @ Scale, host Neciu Dan sits down with Faris Aziz — Staff Front-End Engineer at Small PDF and co-founder of ZurichJS — to talk about scaling frontend systems, the power of BFF architecture, and the human side of engineering culture.

Main Takeaways from my conversation with Faris:

💪 From CrossFit to code.
Faris pivoted from coaching athletes to building software — using personal projects as his bootcamp for real-world learning.

🧩 BFF architecture done right.
A Backend-for-Frontend layer helped shrink payloads from 2.3MB to just 666 bytes, cutting down load times and saving mobile users from flaky 3G connections.

Implicit vs explicit performance.
It’s not about sprinkling useMemo everywhere. True React performance comes from component architecture, primitives, and data shaping.

📊 Architecture is about structure, not speed.
Atomic design, smart state management, and understanding REST vs GraphQL all shape how systems behave at scale.

🔍 Observability over endless tests.
Instead of a massive test suite, Small PDF leans on error tagging, monitoring, and rapid detection to manage outages across 30M users.

🔑 Culture as architecture.
With no heavy processes, engineers own deployments end-to-end. Accountability and trust replace bureaucracy — and build resilience.

🌍 Meetups are micro-architectures.
Co-founding ZurichJS taught Faris that communities scale like teams: structure, delegation, and ownership matter as much as code.

🏍 Balance through focus.
Racing motorbikes forces total focus — the same mindset Faris applies to high-stakes engineering.

React Native at Scale with Kadi Kraman
Episode 35

Señors @ Scale host Neciu Dan sits down with Kadi Kraman, software developer at Expo working on the tools that make React Native development as smooth as possible. Kadi's path started with C++ in a university maths degree, took her through Angular 1, scientific programming for pharmaceutical and defense companies, five and a half years at Formidable, and finally to Expo itself. From the limitations of early React Native to development builds, EAS workflows, fingerprint-based repacks, and the right way to think about over-the-air updates, this is the React Native conversation most web developers never get.

Browser ML at Scale with Nico Martin
Episode 34

Señors @ Scale host Neciu Dan sits down with Nico Martin — open source ML engineer at Hugging Face working on Transformers.js, and Google Developer Expert in AI and web technology — to go deep on running machine learning models directly in the browser. Nico breaks down architectures vs. weights, quantization, tokenizers, ONNX, WebGPU, and why on-device AI is the right answer for a huge class of problems. He also shares the road from ski instructor and self-taught web developer to landing what he calls his dream job at Hugging Face.

Frontend Foundations at Scale with Giorgio Polvara
Episode 33

Señors @ Scale host Neciu Dan sits down with Giorgio Polvara, Staff Engineer at Perk (formerly TravelPerk), who joined when the company was 15 people in two flats with a hole knocked through the wall and helped build the frontend foundations that still hold up at unicorn scale. Giorgio covers the multi-year migration from a monolithic frontend to vertical micro-frontends, why their first attempt with single-spa didn't work, how they pulled off a full rebrand behind feature flags without leaking, and the staff engineer mindset of treating every feature as a system improvement.

Module Federation at Scale with Zack Chapple & Nestor
Episode 32

Señors @ Scale host Neciu Dan sits down with Zack Chapple, CEO and co-founder of Zephyr Cloud, and Nestor, the platform engineer building it, to go deep on module federation, microfrontends, and what it actually takes to go from code to global scale in seconds. They unpack why module federation is Docker for the frontend, how Zephyr composes applications at the edge in 80 milliseconds, and why the real unlock for enterprise teams isn't deployment — it's composition.
