    WHEN done right, a modern iOS mobile application can provide your customers a great way to access your products and services. However, creating and maintaining a modern software application can be a risky venture! There are procedural risks, technical risks, and risks in hiring the right person or team. Some risks are downright unavoidable. That's where I come in. I specialize in creating modern software solutions for individuals, startups, and established companies. Using the latest technologies and engineering methods, I will strive to build you a great mobile solution, while minimizing risks and other factors that can break your budget. During project construction, I can provide a web portal where you can: -- Monitor your project status. -- review daily status reports, bug reports, and project design artifacts. -- access your Git source code repository. -- download and install the latest version of your app onto your iPhone or iPad device. I am well-versed in Requirements Analysis, Object-Oriented Design, and implementing code in Swift and Objective-C using xCode. Experience working in agile, test-driven environments. I'd love to learn about the ideas you have for maximizing your business. Testimonials "Fred was a true asset to us, providing advanced coding skills from years of experience as a software engineer. We highly recommend him for any project, simple or complex. His courtesy, experience and skill set are a blessing." - Geoff Coldiron of OpenDrive, Inc. "I enjoyed working with Fred on some very specific projects that required some creative thinking and high throughput. I found Fred to be a very pleasant and dilligent worker and I think he would be good contributor to any organization." - Bob Steurer of SpaceLabs Medical

Highly recommended." * “Jeffrey was a very good help on our project, always available and ready to present good solutions. I would recommend his work to a friend.” I have been working as an enterprise architect in financial services for over thirty years. I focus on Java, web technologies (HTML, CSS, Javascript, jQuery mobile, web services), Low-Code/No Code solutions (such as Creatio), APIs and new technologies such as cloud services, distributed storage, graph databases, big data tools, application servers (WebSphere, WebLogic, TomEE) and database systems (MS SQL, Oracle, DB2, Cassandra/Titan). I have been working on Elance as technical advisor for several start-ups. One is a start-up in San Francisco that I worked with since May 2014 as their "part-time, remote CTO" -- after documenting the design for their investment management software, then documenting the enterprise software non-functional requirements that they need to meet to be taken seriously in the financial services world, and was their "technical project manager" for over 6 months. I have also helped them on their business continuity planning and information security programs that they need in place to connect to some large investment firms. Another is a more mature start-up in Indonesia, but they have several challenges with the organization of their IT team and development activities. I am helping them to put in place methods, tools and procedures. I work regularly with other smaller start-ups; all related to their IT activities and most of them with a focus on efficiently outsourcing to lower-cost resources.

    I have worked in software development for 15 years both as coder implementing backend (Java) and front technologies (HTML, CSS) as well as a software architect. I have been responsible for end user documentation for APIs as well requirements and design specifications. I've worked with various project stakeholders and clients to develop requirements and projects plans. I have worked with UX engineers to help refine designs and created mocks ups of wireframes, UML diagrams and other visual assets. When not working, I am a singer/songwriter. I have released multiple albums and perform regularly in the Bay Area. I maintain my own music publishing company and my own website as an artist. I have been writing creatively from a young age -- I was illustrating my own short stories as early as kindergarten and wrote the play for the student production my senior year of high school. I also paint with acrylics.
