// WHO I WORK WITH

WHO I HELP

Series A-B startups ($2M-$20M raised) who need engineering leadership without the $300K salary.

Best fit if you're:

  • Scaling 5→30 engineers
  • Preparing for Series B diligence
  • Stuck at 2-week sprint cycles
  • Between CTOs or can't afford one yet

WHO I DON'T HELP

Not every engagement is the right fit. I'm transparent about when we shouldn't work together.

Not a fit if you:

  • Need full-time, on-site presence
  • Want someone to just write code
  • Aren't ready to make hard decisions
  • Have <5 engineers (you need a senior dev, not a CTO)

// CAREER HIGHLIGHTS

Led search platform through $550M Target acquisition. Rebuilt core search architecture to handle 10x traffic spike (1M → 10M queries/day). Reduced P95 search latency from 850ms to 120ms. Delivered complete technical DD package: zero follow-up questions from Target's engineering team.
SHIPT / TARGET
Dismantled monolith by 70% in 18 months. Cut deployment time from weekly multi-hour deploys to 15 minutes on-demand. Reduced production incidents 70% (18 per quarter → 5). Hired 20+ engineers.
MINTED
Delivered zero downtime during Black Friday weekend ($12M+ in 24hrs—Minted does >60% annual revenue Nov-Dec). Handled 2000% traffic spike vs. January baseline with zero rollbacks.
MINTED
Navigated RentJuice → Zillow acquisition. Merged two engineering teams (24 total engineers), standardized tech stack (Ruby + PHP → unified Node/React), maintained 100% feature delivery during 4-month integration. Zero attrition among senior engineers post-acquisition.
RENTJUICE / ZILLOW
Built world-class app search engines using Elasticsearch, Solr, and Algolia, with a focus on relevancy and performance.
VARIOUS STARTUPS
Interviewed 500+ engineering candidates across all levels. Refined hiring processes that reduced time-to-hire from 90 days to 35 days while improving offer acceptance rate from 40% to 75%. Built high-performing teams that consistently delivered.

PROJECTS

Holler

Low-pressure social hangout app connecting IRL friends for spontaneous meetups. Built from the ground up with Swift/SwiftUI and live in the App Store.

AI Tools

Developing internal tools that leverage AI to speed up coding, automate testing, and generate documentation. Aiming to reduce development time by 30%.

EXPERTISE

  • Breaking Bottlenecks: Find where velocity dies (usually: unclear ownership, no code review process, or technical debt paralysis)
  • Preparing for Diligence: Make sure you have good answers when VCs ask about your tech stack
  • Hiring Without Chaos: Define real technical bars, interview effectively, close candidates who move the needle
  • Making Hard Decisions: Cut projects that aren't working, restructure teams for clarity, tackle technical debt—I help you move forward when you're stuck

// WHAT CLIENTS SAY

"What truly makes Brian special isn't how much he cares about the tech, it's how much he cares about the people. He never stops pushing his team to grow technically, professionally, and personally. He isn't afraid to make hard decisions if he knows it is in his engineers' best interest in the long term."

— Nick Guertsen, Director of Engineering, Shipt

"Brian is the rare combination of extremely intelligent, hard working, and easy to talk to. I've seen him tackle complex problems with utmost confidence, and come up with a solution that he could articulate simply. He is a great motivator, and he cares deeply about his teams. He's down to earth and always willing to lend a helping hand. It would truly be a shame not to work with Brian!"

— Elliot Potter, CEO of Linq (Seed Round)

"Brian grew our team from 2 to 25 engineers with zero turnover. His toolbox of strong business intelligence, effective leadership, and empathetic mentorship produced one of the highest performing teams in the company."

— Jeffrey Chang, Engineering Manager

"Brian very clearly stated his 5-year plan was to be running the department. I managed him for 3 years and watched him grow from managing 2 people to leading 25+ engineers. His radical candor was always received well and his team flourished as a result. His team was a reflection of him: high quality, dedicated, and always delivering results."

— Bryce Catlin, VP Engineering

"Indecision is worse than making the wrong choice. At least with action, you learn something."
— James S.A. Corey, The Expanse

// HOW IT WORKS

01

Engagement

15-20 hours/week for 6-12 months. Enough to move the needle, not so much you're paying for a full-time exec you don't need yet.

02

Investment

$10K-$18K/month depending on scope. Less than half the cost of a full-time CTO ($250K+ salary + equity + benefits).

03

First 30 Days

Team audit, identify bottlenecks, fix immediate process issues, create 90-day technical roadmap aligned with your fundraising timeline.

04

Exit Strategy

When you're ready for a full-time CTO, I'll help you hire them, do the handoff, and transition out. Or stay on as advisor. Your call.
