Omar is one of the most professional and highly skilled engineers I have ever worked with in my 20 years delivering technology. His role was Lead Architect and Data Scientist on a program to develop a custom Machine Learning Platform for a top 10 global telecom client. The work he delivered exceeded client expectations and has been a foundation for our clients ML journey for the next few years.

Omar is a dedicated professional that knows how to get things done. He was a pleasure to work with and is incredibly capable and helpful. Hire him whenever you need something done right, or when you need something impossible pulled out of a hat. He is a life saving wizard... He will cast a spell and make results magically appear! Trust me on this one.

First time request with a large budget. Omar was excellent as always. He was quick to understand the brief. Came back very quickly with interim results of his work for review, was flexible on time for video calls and delivered as requested on time and budget. Hugely impressed and will use again. Many thanks Omar!

Frequently Asked Questions

Send me an email describing your goals, success metrics, budget, timeline, and data. If I'm a good fit for you, I'll reply with a link where you can schedule our call. If I'm not a good fit, I'll try to point you in the right direction.

We will use a portfolio strategy to maximize your value. We will brainstorm many potential POCs and will select a few to move forward based on risk, reward, and effort estimates. The objective is to select a portfolio that maximizes the likelihood of us achieving enough value, even if some POCs fail. Here's the process I follow with every client:

  1. Discovery: let's diagnose exactly what you need.
  2. Strategy: let's make sure the portfolio selection is robust.
  3. Development: let's iteratively converge to a working solution.
  4. Validation: let's make sure it works inside your business.
  5. Transfer: let's empower your team to continue to evolve it.

No. I help teams before an RFP can exist. If you already have one, you're set on a specific path and the value I can provide is reduced. I only develop for clients that go through the discovery and strategy phases with me.

I use fixed-pricing with shared risks and rewards. I do not provide time-based rates for projects (e.g. hourly rates) because doing so produces bad incentives: the slower I am the more I get paid. I want to get payed for being effective and efficient, and fixed pricing puts the risk on me, the expert.

If necessary, but in most cases it is not. I work remotely and that works fine for most projects. If your particular case would benefit from meeting in person, I'd be happy to do so once we setup a reimbursement mechanism.

Yes. I often help companies with their own clients. I will represent your company when interacting with your client. If we're working through a project, these will be included in the fixed price. If we're working through a retainer, these will count towards your call time.

Yes. I'm happy to refer potential clients to other established experts. Send me an email describing what types of projects you believe you're a good fit for. I'll add you to my list of experts and refer you to potential clients when you seem to be the best fit. Please note that refererals are not endorsements.
