I'm being serious here.

Contact & Business

You can contact me via email or by reaching out on LinkedIn.

I am the sole proprietor of a business registered under the name A battle tested one-man army for growing and scaling software technology ventures. I combine deep technical skill, business acumen, data savviness, and common sense to help clients successfully execute their go to market strategies. I am a former CTO and co-founder in both product and consulting businesses.

My focus is on high impact roles at starting or scaling software product ventures with appropriate (corporate) backing. I excel in roles where versatility is rewarded. I often find myself working out budgets to get a runway projection, setting up hosting for a new company website, and managing a hiring funnel, while evolving technology vision on the same day.

Recent Engagements

Here is a selection of recent engagements for your review.

Shackle — the greatest hotel app on the planet

Shackle is a hospitality tech business founded by Mark Abraham, and backed by Frontline Ventures.

Shackle improves hotel guests' lives by removing the in-person check-in procedure at the front desk, and providing a mobile room key on a guest's smart phone by leveraging bluetooth enabled door locks common in today's hotels. Shackle helps hotels generate revenue by creating a direct digital channel to the customer, providing opportunity for upsell of goods and services.

At Shackle, I acted as interim Chief Technology Officer and member of the leadership team leading up to preparation for VC backed seed funding. Shortly after a permanent replacement was recruited and hired for the role, a $5.5m funding round led by Frontline Ventures was secured.

I delivered the following activities and outcomes:

  • From zero lines of code written to product go live at the launching customer hotel in six months.
  • Sunset existing relationship with under-delivering third party development shop.

  • Establish a architecture for quick iteration on Shackle's integration strategy and implementation.

  • Establish a culture of aggressively prioritising activities with go-to-market impact over satisfying internal vanity goals.

  • Lay down a technology vision and roadmap balancing short term product viability and near term platform foundation.
  • Draft and prototype a protocol for dynamically configured multi-device computing (based on gRPC, implemented in Python, if you were curious).
  • Align road map initiatives with go-to-market timeline.

  • Detailed descriptions and criteria for ML roles in BEAT engineering, used for internal alignment on the hiring procedures.
  • Production of hiring copy, including job descriptions.
  • Exploration of channels for lead generation, including extensive utilisation of my existing network in the data science and machine learning communities.
  • Analysis of data acquired through web scraping to identify relevant communities and their activity to optimise lead generation.
  • Leading multiple workshops on hiring and assessing for machine learning and data science roles.

Speaking Engagements

Public speaking is not one of my commercial activities, hence there is no charge. When travel and / or lodging are required, it is generally appreciated to be compensated for that though.

I can be approached for any speaking engagement where there is a good match with the audience and I will have fun being there. I arbitrarily decide case by case whether I want to speak at an event.
