How I turn business problems into software systems
I help service businesses, agencies, and startups turn manual workflows, disconnected tools, and unfinished software ideas into AI-assisted web, mobile, and automation systems.
Map the operational bottleneck
I look at how work moves today: intake, processing, review, action, reporting, and follow-up. The goal is to find where time, context, and revenue are leaking.
Design the software workflow
I turn vague business pain into a clear product workflow: user journeys, roles, data models, integrations, MVP scope, and what should be built first.
Build the web, mobile, or internal tool
I can stay hands-on across React, React Native, Node.js, Python, Firebase/Google Cloud, AWS, APIs, databases, DevOps workflows, and product delivery.
Automate the repetitive parts with AI
Where it makes sense, I add AI-assisted workflows for summaries, classification, missing-info detection, lead research, CRM updates, reports, and next actions.
