Simple, Direct Engagement
Discovery Call
Brief conversation to understand your needs and technical landscape. No sales pitch — just a straight assessment of whether I can help.
Scope & Proposal
Clear deliverables, timeline, and rate. You'll know exactly what you're getting before any work starts. No surprises.
Execution
I embed with your team and get to work. Direct communication, fast iteration, and real technical output from day one.
Independent by Design
Large consulting firms staff projects with a partner who wins the deal and a bench of junior resources who do the work. You pay senior rates for junior output, and your project becomes a training ground for someone else's career development.
