I have 40 years of experience in business and technology related industries. My experience in the Pharmaceutical industry alone exceeds 25 years. I have been responsible for the creation of a number of business solutions from small business to worldwide corporations. I have dealt with a range of clients from senior executives to front line clerks. Every project I have been involved in has been a success. During the past 40 years, I have guided my corporation through years of success as an independent consultant, a task that is not achieved by many in the industry. Recently, I have developed a web based application for the Victims’ Advocates in the Surprise Police department. The system maintains interactions with the advocates and their clients. The application utilizes MySQL databases as well as PHP technologies to provide a very robust tool for the advocates. As part of a volunteer project, I have adapted Raspberry Pi devices to work with a VOIP product (Mumble) to help the Civil Air Patrol more efficiently communicate with their staff during mission critical events. I created the entire server structure to process all user management as well as the setup of the Mumble server. Again, MySQL, PHP and python were some of the tools utilized. I have revolutionized several pharmaceutical companies to properly manage their sales and promotional marketing budgets during the last 25 years. The last development introduced new procedures through extensive change management so they could manage a budget approaching 1 billion dollars. The resultant technology solution that I implemented managed over 3500 projects and affected over 350 end users in the past year. The system managed both production schedules as well as budgets. In addition, it interfaced directly with SAP to tightly integrate all financial data as well as purchase activity. I designed and developed a web-based system to manage all of the Field Sales promotional spending for over 4000 sales representatives. The funds and budgets were integrated into the budget management system and thus help increase sales revenues by timely use of budget dollars. I have worked with one of the leading genetic research branches of a large pharmaceutical company for over 15 years. The tasks accomplished have been in a wide range of disciplines including laboratory system development, legal tracking, research budget management and product sales support and web site development. I have designed and developed a system to manage all of the purchases of bulk cement for the world’s third largest cement manufacturer (at that time) for sales in the United States. The system integrated all the sales with the general accounting system and produced all the accounts receivable documents. I also provided technical support to their staff and installed and maintained various network configurations in extreme work environments. I have worked various other industries throughout the United States. I have worked in the governmental arena (Federal and State), a private world-wide consultant firm, a computer manufacture’s software development area and a wide variety of private industries. Summary - Developed online web based Victims Assistance application utilizing MySQL/PHP technologies for the city of Surprise Police Department.

I’m a Senior Java Backend Engineer with over 14 years of experience building mission-critical systems in fintech, with a strong focus on payments, lending platforms, and core banking solutions. I specialize in Java and Spring Boot, and design backend systems that are secure, scalable, and capable of handling high-volume financial transactions with consistency and reliability. I’ve worked on systems involving payment processing, transaction workflows, loan management, and integrations with external financial services and APIs. This includes designing and building robust microservices architectures that support real-time and asynchronous processing, ensuring data accuracy, fault tolerance, and seamless service communication. I understand the importance of idempotency, transaction integrity, and failure handling in financial systems where even minor inconsistencies can have significant impact. Security and compliance are central to my approach. I have strong experience implementing secure authentication and authorization using Spring Security, token-based systems, and role-based access control. I build APIs and backend services that align with financial industry expectations around data protection, auditability, and reliability. From a technical standpoint, I bring deep expertise in Spring Boot, microservices, REST API design, JPA/Hibernate, and relational databases like MySQL and PostgreSQL. I’m comfortable designing systems from scratch as well as improving and scaling existing platforms, optimizing performance, and ensuring stability under load. I also have hands-on experience with AWS and Google Cloud, and have worked on deploying and managing backend systems in cloud environments. I understand how to design cloud-ready architectures, implement CI/CD pipelines, and ensure systems are resilient, observable, and production-ready. What sets me apart is my ability to think beyond just implementation. In fintech systems, correctness, reliability, and long-term maintainability matter more than quick fixes. I focus on building clean, well-structured systems that not only meet current requirements but are also prepared for future scale, regulatory needs, and product evolution. If you’re building or scaling a payments platform, lending system, or core banking backend and need someone who understands both the technical and domain challenges, I’d be glad to contribute.
