About Us

Hey there! We're Ones & Heroes, and at the helm is Leewyn Jacobs—a senior .NET full-stack engineer and technical leader with over 20 years of experience in the software industry.

Over the past two decades, Leewyn has designed and built platforms across industries from fintech and gaming to social enterprise and professional services. His speciality lies in .NET and Node.js backends paired with modern React frontends, delivered on AWS and Azure cloud infrastructure with Terraform and Azure Bicep—but the real superpower is translating complex business problems into clean, scalable technical solutions. More recently, we've been helping startups integrate AI capabilities into their products using OpenAI and Claude APIs.

Ones & Heroes was founded to give startups and small businesses access to the same calibre of senior engineering leadership that established companies take for granted—at a scale and price point that makes sense for early-stage ventures. Whether you need a technical co-pilot for your next product build or a seasoned hand to modernise an existing platform, we're here to help you punch above your weight.
