PP Pat Paluch

Staff frontend & product engineer

I build frontend systems that make complex products easier to ship.

Across BuzzFeed and Complex Networks, I turned AI workflows, editorial tools, publisher platforms, and custom advertising into reusable product systems. My focus is clarifying ambiguous work, designing the contract between interfaces and services, and leaving teams with a better path to the next launch.

How I create leverage

Staff impact through systems, not just launches.

I work where product definition meets frontend architecture. That often means taking a loosely defined request, finding the durable technical model inside it, and aligning product, engineering, and operations around something teams can build and maintain.

At BuzzFeed, that looked like connecting LLM output, editor state, live previews, and canvas rendering through shared data contracts. It also meant reshaping campaign tooling around the real workflow used by engineering, RevTech, and AdOps—and making the case for dedicated infrastructure when the existing stack imposed limits.

Earlier, at Complex Networks, I modernized a publisher platform deployed across more than 100 partner sites and co-architected the tooling used to manage and ship rich-media campaigns. The thread across the work is the same: make complexity explicit, build the reusable layer, and keep delivery moving.

Experience

Growing scope from execution to architecture.

The two roles most relevant to my current work, followed by the earlier product experience they build on.

2021 — 2026 BuzzFeed · Remote

Senior Web Engineer → Staff Engineer

AI products and custom advertising platforms
  • Defined reusable AI-builder architecture. Connected structured LLM output, JSON configuration, editor state, live previews, shared APIs, and canvas rendering across Generator Generator and BF Island Builders.
  • Created leverage beyond a single launch. Built the OpenAI Quiz UI foundation used for four production quizzes and later AI experiences across BuzzFeed, Tasty, and HuffPost.
  • Modernized campaign operations. Partnered with RevTech and AdOps to redesign how bespoke campaigns were built, previewed, packaged, and deployed; secured dedicated S3 infrastructure to remove asset-type limits in the existing stack.
  • Delivered under changing constraints. Shipped custom chat and branded AI experiences, including a high-priority AI filter in 2.5 days and a navigation-token system for a more structured Cathay Pacific chatbot flow.

2012 — 2021 Complex Networks · New York

Web Developer → Senior Web Producer

Publisher platforms and branded experiences
  • Modernized platform infrastructure and ad delivery. Led modernization and optimization of Catalyst Creator, a JavaScript monetization platform deployed across more than 100 partner sites with shared ad delivery, video, analytics, configuration, and integrations. Streamlined ad delivery, improving initial ad load speed by roughly 15-20% on desktop and 35-50% on mobile.
  • Co-architected an operational product. Helped build an Angular and Laravel CMS that engineers and Ad Implementation Managers used to manage, preview, package, and deploy rich-media campaigns to Google Ad Manager.
  • Built over 250 branded campaigns. Over nearly 10 years, delivered work ranging from 24-hour takeovers and run-of-site units to multi-month campaigns, including billboards, 300×250 and 970×250 units, animated banners, skins, overlays, pop-ups, audio ads, and responsive custom formats.
  • Engineered formats beyond standard ad units. Created the “Superhero” format with one 640×360 image and one 640×360 video displayed side by side on desktop and stacked on mobile; 300×50 toolbar triggers that expanded full width; content-injected effects such as horror overlays on article images; Samsung’s interactive “X-ray” reveal; and Hot Ones audio units featuring short participant quotes.
  • Owned polished client delivery. Built interactive campaign sites and video experiences for major brands, including the linked Beats by Dr. Dre and Las Vegas editorial experiences.

Selected case studies

The decisions behind the shipped work.

These are architecture summaries, not invented outcome stories. Each one separates the problem, my contribution, and the evidence available.

01

AI creation platform · BuzzFeed

One data contract from prompt to editable canvas

Problem

AI experiences were becoming a family of products: user input had to become structured model output, flow into a live preview, and remain editable inside a visual builder.

My contribution

Led core engineering for Generator Generator and BF Island Builders. Designed the relationship among JSON configuration, Mustache variables, LLM output, editor state, shared APIs, renderers, and a Fabric.js canvas layout block.

Leverage created

Refactored the approach toward shared components and configuration-driven formats, establishing a reusable path for new builders instead of treating each experience as a standalone implementation.

Evidence
First Island Image Builder
Usage
Tens of thousands of created pieces
Core stack
React, JSON, Canvas / Fabric.js, LLM APIs
02

Campaign operations · BuzzFeed

A delivery platform shaped around the people using it

Problem

Custom campaigns crossed engineering, revenue technology, and AdOps, while the existing asset workflow constrained the formats the team could deliver.

My contribution

Defined requirements and technical architecture with the teams doing the work. Rebuilt the flow for managing, previewing, packaging, and deploying campaigns around their actual handoffs rather than a generic CMS model.

Leverage created

Made the business and technical case for dedicated S3 infrastructure, removing asset-type limitations and giving custom formats a more flexible delivery path.

03

Publisher platform · Complex Networks

Platform scale and custom ad engineering across 100+ sites

Problem

A large publisher network needed consistent advertising, video, analytics, and configuration behavior across many independently operated sites—while branded campaigns still demanded custom, highly interactive executions.

My contribution

Modernized and optimized Catalyst Creator, the JavaScript platform that centralized those capabilities and integrations. Alongside the platform work, built a conservatively estimated 250+ branded campaigns across standard, animated, audio, and custom responsive formats.

Leverage created

Maintained a shared layer for delivery and measurement while extending the creative surface with reusable patterns for takeovers, skins, overlays, expandable units, content effects, and other bespoke campaign ideas.

AI product foundation

AI Quizzes & Chats

Evolved a proof of concept into four production quiz experiences and a base other engineers used for later products.

High-priority launch

Drake AI Filter

Shipped an unplanned AI experience in 2.5 days under a compressed timeline.

Brand constraints

Sprite: 50 Years of Hip Hop

Iterated on prompt guardrails for an open-ended branded conversation that could not name musical artists directly.
