How I can help
Prompt design
I craft prompts that do exactly what you want them to do, and avoid what you don't. In the format your app or service needs.
Prompt optimization
I review a prompt you already use, suggest improvements and optimize it so you cut costs, get better results and eliminate errors & inconsistencies.
GPTs
I create a complete GPT (personalized version of ChatGPT with your own prompt) from scratch. Use it for your personal productivity, share with your team or publish on the GPT Store.
AI consulting
I help founders and teams navigate the messy AI landscape, overcome overwhelm around AI and find practical, easy-to-tap opportunities for optimization & revenue.
System engineering & APIs
I help you figure out the dance of API variables like system, user & assistant messages among other moving parts. I make sure the elements are organized efficiently so your app just works.
Testing & tamper-proofing
Any prompt that you get from me is tested and optimized to account for possible abuse and edge cases. No unpleasant surprises.

About me
I've been working & experimenting with AI, both cosumer-facing and APIs, ever since ChatGPT saw the light of day in November 2022. Since then, I've crafted 260+ megaprompts (+ countless iterations) for my own business, other people's apps and personal productivity.
I've helped 30+ founders across verticals, from newly-minted startups to established solopreneurs like Justin Welsh, to build and enhance their products with AI.
In the process, I accumulated a sizable war chest of techniques, tips and strategies to use AI, especially for business, at an advanced level.
My specialty is business applications of AI which I use every day for a wide range of use cases from ideation, writing, marketing & business planning to complex multi-step product features.
But I also made LLMs work for numerous less conventional applications: produced high-quality designs as a non-designer, implemented code as a non-tech founder and came up with powerful UX & app features without formal training.
Since 2021, I've worked on over a dozen of my own products (and buried most). Apart from Promptnik, I'm now building Smasher of Odds (AI business plan generator), Sito (AI food diary analysis) and Unfile (doc to text conversion for AI APIs). Through these ventures, I get daily hands-on experience with implementing AI in nearly every aspect of business.
For my previous "main hustle", Brick, I built three AI features and achieved a 4x monthly operating cost reduction in under three months once I started using AI seriously.
