Hello there! My name is Michael, and I'm a backend engineer with over 10 years of experience building production backend systems. I'm here to be a senior, experience-based resource that can help you navigate difficult integrations, optimize existing systems, and of course, help you design your own systems from scratch. My 100% success rate is a good reflection of the quality I bring to all of my work, and my dedication to ensuring the project succeeds. During my time on Upwork, I've architected high-performance APIs, HIPAA-compliant systems, and worked with clients across healthcare, law, and government domains. I've listed a few examples below, and my project history has more, with client reviews for reference. Few examples: - Built high volume APIs handling 10M+ requests per month, allowing client data that was previously entered manually to flow directly into the right CRM workflows at scale. The system is built to be modular and work with a variety of vendors, which allowed the company to rapidly scale its acquisition of new clients, and process their data efficiently. - Developed a lead processing system, integrated with Retell AI, that allows for automated qualification of leads, follow up workflows depending on the lead status, and an always on presence that has led to a 10% increase in booking conversions. - Designed HIPAA aware backend systems for healthcare workflows involving sensitive data, access controls, auditability, and operational reliability. I have experience with EHRs, such as NextGen and Epic. - Implemented a GIS API and backend platform for a government client, working from provided specifications to deliver spatial data integration, secure access patterns, and multi-environment deployment workflows. If you need to automate workflows, connect systems, or build a scalable backend or AI integration, send me a message with what you are working on. I am happy to take a look, talk through the workflow, and let you know where I can help.

I have 10+ years experience in developing a wide range of database and web applications such as crm, mrp and medical systems using front-end tools such FileMaker, Delphi and C++Builder and back-end tools such as mySQL, PostgreSQL, Firebird and SQLServer. My main expertise though is FileMaker and I am well-versed from 5.5 to the latest version 19. I have excellent Scriptmaker skills, good AppleScript skills, excellent knowledge of the use of a variety of plug-ins, good interface design, reporting skills and project documentation skills. I am easy to work with and communicate with and most of the time available online.
