Why Work With Me

I bring a unique combination of technical depth and business perspective. My 18 years as an entrepreneur give me insight into what actually drives value, while my technical portfolio (200+ deployed applications) demonstrates ability to ship production-ready solutions. I excel at translating ambiguous business requirements into concrete technical plans, architecting integrations that scale, and driving execution across technical and non-technical stakeholders. My multilingual capabilities (5 languages) and cross-industry experience (finance, education, tourism, tech) enable effective collaboration in diverse contexts. I'm passionate about leveraging AI to remove barriers to creation – helping founders and businesses build faster without traditional technical constraints.
