Marc Adler is the former Chief Architect of Citigroup, MetLife, XP Investments, and ADP, and the former CTO of various startups. For the past 5 years, I have been a fractional CTO under the banner of "CTO as a Service" (ctoasaservice dot org), where I have helped dozens of startups. I am available to help your company to develop and troubleshoot your technical team and help you bring your ideas to fruition. If you need someone to code up your application or MVP, I can even get down and dirty with the code. Since starting CTO as a Service in late 2018, I have helped companies in EdTech, Real Estate Tech, Health Care and Wellness, financial services and trading, and many more. My model is to charge you for what you use, in the same manner that you would employ a lawyer or an accountant. You can use me for one hour a month, one hour a day, or 8 hours a day. Here are some of the ways that I could help you. * Vision: Helping you realize your vision by helping to assemble a development team and leading them to develop a product * Innovation: Taking an existing product and helping to move it to the future state * Opinions: Assessment of your current applications and development organization * Confidence: Meeting with investors. Often times, an investor will be more comfortable knowing that there is someone with a lot of senior-level experience behind the scene. * Design: Architecting and designing systems, especially cloud-based systems * Refactoring: Transforming your system into microservices * Hacking: Writing production-quality code * Documentation: Writing technical roadmaps and white papers * Faceoffs: Performing product evaluations * Due Diligence: Vetting vendors, and facing off with CEO’s, CTO’s and Chief Architects from other organizations References are available on request.
