Built together
Great products need
strong foundations.
I help at every layer: the people who build it, the systems that support it, and the product your customers use.
02 / The platform
Give them a foundation they can trust.
Build scalable, robust, and secure infrastructure that helps your team ship confidently. Put automation to work so growth doesn’t mean more manual effort.

03 / The result
Put something useful into the world.
Turn an idea into a prototype, launch an MVP, or build a complete software product. Connect the technical work to what your customers and business actually need.

01 / Experience in practice
Built from scratch.
Tested at scale.
I’ve been a startup CTO, a hands-on engineer, and an engineering leader. Here’s what that experience has looked like in practice.
Kueski / Infrastructure & engineering leadership
100+ developers
An infrastructure team built to support them.
Built the infrastructure and DevOps function from a one-person operation into a multi-team organization. Established automated, security-focused infrastructure for a regulated fintech serving more than 100,000 users.
Amazon / Devices
Days → hours
A shorter path from code to delivery.
Led a project to reduce lead time for changes in the Devices organization, helping engineers move work through the development lifecycle faster.
Keep Technologies / Banking
~40%
Of customer payments through a new channel.
Led the project to create a new payment channel that went on to receive roughly 40% of customer payments. Helped restructure and relaunch teams, then led Risk and Growth work focused on application hardening and new growth opportunities.
AcerosVS / Consulting → Engineering director
>20,000
Tons sold per month.
Built and now lead the software infrastructure and internal tools supporting a steel business selling more than 20,000 tons per month. From consulting partner to engineering director, I’ve helped build the systems behind that growth and am now integrating AI into the company’s technology strategy.
02 / How I can help
What does your
business need next?
A first product. Infrastructure you can depend on. A team that takes ownership. I bring the engineering depth and leadership to work on these together.
01Build your product
Get from idea to a working first release.
You know the problem you want to solve. I help define the smallest useful product, choose the architecture, and build it with you. My experience as a startup CTO keeps the focus on what you need to learn from customers.
- MVP scope & architecture
- Hands-on product development
- Data integrations & internal tools
A product you can put in front of real users.
02Strengthen your platform
Give your engineers room to move faster.
Slow releases, fragile infrastructure, and manual work take time away from your product. I get into the systems with your team, identify the constraints, and improve the foundations behind delivery, reliability, and security.
- Infrastructure & architecture review
- Deployment automation & developer tooling
- Security & reliability improvements
Less friction between a good idea and production.
03Build your team
Hire well. Help people grow.
Your first hires shape how the whole team works. I help you define roles, assess technical judgment, and build a culture of clear expectations, ownership, and support. For existing teams, I coach engineers and managers through their next stage.
- Hiring priorities & technical interviews
- Team structure & engineering practices
- Coaching & career development
People who can take on more, with the support to succeed.
04Set your technical direction
Make the big calls with an experienced partner.
Deciding what to build, what to buy, or where AI can help? I connect the technical options to your business priorities, make the tradeoffs clear, and help turn the decision into a practical plan.
- Ongoing technical advisory
- Roadmap & build vs. buy decisions
- AI strategy & implementation planning
A clear next step, with the reasoning behind it.
03 / Your technical partner
A builder’s instincts.
A leader’s perspective.
I’m at my best where software, infrastructure, and people meet. I can work through an architecture decision, get into the code, and help the team develop the judgment to own it.
As co-founder and CTO of MovingLake, a Y Combinator company, I built real-time data integration technology with Rust, Go, and Kafka. At LandingAI, I helped design and implement infrastructure for large-scale machine learning inference. Those experiences inform how I approach data systems and AI today.
My foundation is electrical engineering at Tecnológico de Monterrey, Campus Ciudad de México, where I graduated with the highest GPA in my program. My career since has taken me from early-stage companies to Amazon, with consulting work alongside operating roles.
04 / Working together
Clear priorities.
Hands-on progress.
You work directly with me. We agree on scope and how I’ll be involved: a focused build, a platform improvement project, or ongoing technical guidance.
- 01
Start with what’s at stake.
We talk about your customers, business goals, and what’s getting in the way. I look at the relevant systems and team context before recommending a direction.
- 02
Choose the work that matters.
We agree on priorities, deliverables, and what success looks like. You’ll understand the tradeoffs and what we’re deliberately leaving for later.
- 03
Build capability as we deliver.
I work in visible increments and share the reasoning behind decisions. Your team gets the code, documentation, and context to keep moving after the engagement.
05 / Let’s talk
What’s your next
big technical challenge?
Tell me what you’re building, what’s getting in the way, and where you’d like help. We’ll start there and work out whether I’m the right partner.
