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.

Señors @ Scale host Neciu Dan sits down with Craig Abbott, Principal Accessibility Specialist at TetraLogical and the former Head of Accessibility at the UK's Department for Work and Pensions, one of the largest government departments in the country, where he built a dedicated accessibility practice from nothing and open sourced the DWP Accessibility Manual. Craig has over 15 years in user centred design and has led accessibility work across the public sector and at Elastic. From what sustainable accessibility actually means and why third party audits alone don't get you there, to the three C's of compliance, culture and capability, to running screen readers in VMs without expensive licences, to accessibility acceptance tests in CI with Playwright, Cucumber and Guidepup, to why compliance does not mean usable, this is the accessibility conversation for teams who want it to survive the person who cares about it.
Señors @ Scale host Neciu Dan sits down with Carmen Huidobro, CTO at Incredible Bee in Vienna, where she builds products and helps teams figure out what should be automated and what should stay in the hands of users. Carmen has spent 17 years in tech, almost all of it freelancing, working across Objective-C, Ruby on Rails, the web, mobile, hardware, and even ABAP inside an SAP consultancy, plus five years in developer relations and developer education. Her argument is that the generalist versus specialist debate misses the point: the durable skill is being an expert at adapting. From adding a local Mistral model to a twenty-year-old macOS app without betraying the people who use it, to the refugee hackathon project the City of Vienna still runs a decade later, to why she won't take money from junior developers, this is a conversation about the skills that survive the shift.
Señors @ Scale host Neciu Dan sits down with Marko Gaćeša, Head of Product at Semaphore, the agent-native CI/CD platform, and the first product guest on the show. Marko is a serial entrepreneur whose career spans developer tools, IoT, industrial automation and enterprise SaaS, including founding Dry Tools and serving as Chief Product Officer at Alchemy Cloud, with earlier work in domains like medical equipment where quality is non-negotiable. From why testing rather than coding is now the bottleneck, to what agent-native CI/CD actually means when developers live inside their coding agent, to how SemAI attacks flaky tests and automates migration off GitHub Actions, to pricing a platform where a minute of CI is not the same minute everywhere, this is the product side of developer tooling from someone shipping it.
Señors @ Scale host Neciu Dan sits down with Maxim Salnikov, AI Dev Tools Solution Engineer at Microsoft, where he leads AI native development enablement for over 100 enterprise customers of Microsoft and GitHub in Norway. Maxim has been building for the web since the late 90s and spends his days inside real enterprise dev teams across finance, energy, agriculture, and pure software companies, watching AI adoption succeed and fail. From why adoption is a change management problem rather than a technology one, to the anatomy of an AI harness and the external layer successful companies build on top of it, to the context engineer and agent ops roles now appearing in team topologies, to managing agent skills as versioned dependencies instead of letting them pollute the repo, this is the enterprise AI adoption conversation from someone who sees a hundred versions of it.
