Office Hours

I regularly speak with founders, engineers, and people interested in technology and business. Many of these conversations start with a simple question about building a product, choosing the right technology, or navigating a career in tech.

To make this easier, I’ve opened up a few weekly office hour slots where you can book time to discuss a specific topic or challenge.

These sessions are informal and focused on helping you move forward with clarity based on my experience building software, leading engineering teams, and working with businesses to launch tech products.

Things we can discuss

Building a web or mobile app
Choosing the right tech stack
Tech startup or business ideas
Becoming a senior engineer
System design and architecture
Building an engineering team

Available sessions

Deep-dive session

50-min session

If you want a deeper discussion or help working through a specific problem, you can book a paid 50-minute session.

These sessions are useful for things like:

reviewing a product architecture
discussing a startup or product idea in detail
working through technical decisions
getting structured advice on career progression
reviewing an AI-generated or “vibe-coded” app for risks or improvements

Free office hours

20-min session

I offer a limited number of free office hour slots each week. These are intended for quick questions, advice, or getting a second opinion.

These sessions are ideal if you:

have a quick question
want a second opinion on a tech decision
want general advice about a product or career step

Because availability is limited, these sessions are intended to be short and focused.
