Available to hire
I’m Lindsay Jackson, a Senior Software Engineer with over 10 years of experience delivering scalable, high-performance web and mobile solutions across healthcare, finance, retail, and education. I specialize in cloud-native architectures, microservices, and full-stack development using C#, ASP.NET Core, React.js, TypeScript, Node.js, and Python. I design secure APIs, real-time systems, and maintainable platforms, and I’m passionate about automation, DevOps, and building solutions that improve reliability and user experience.
Throughout my career I’ve led cross-functional teams, driven large-scale cloud migrations, and shipped mission-critical platforms used by millions. I focus on security, HIPAA, HL7, and FHIR compliance while optimizing performance and operational efficiency. I enjoy collaborating with data scientists to apply analytics and ML, and I love turning complex requirements into robust, scalable software that makes a real impact.
