Recommendations

  • John Kottis is a strategic leader and amazing person with great technical skills and people relationship skill. As a technologist, he aligns technology solutions with their business objectives and implements them.

    As a technology lead, he provides inputs and develops expertise in a variety of concepts, practices, and procedures; demonstrates and reinforces the value of our customers to ensure client retention; identifies and establishes strategic long-term technology goals, policies and procedures for clients based-on business objectives and budget requirements; and designing and overseeing the implementation of technology solutions.

    Rajat Mathur, Associate Director at Sapient

  • I highly recommend them for his amazing leadership qualities; he is more than his role title. I am excited to see him move up in his next role. In the future, I can easily see him as Head of Technology/digital, cyber, or CIO of a fintech or rising mid-tier organisation. These companies take aggressive market share from other businesses, with their senior roles possessing both leadership & the technical skills to execute low-cost, fast-paced and highly cross-functional teams.

    Watching him at work, I saw above and beyond performance in his complex role, which covered; “Technical Design”, “Solutions Architecture”, “Software Development”, “Cloud (Azure/Google/Aws)”, “Agile” & “Digital innovation” of £M0 digital products, projects and £M00 programs.

    His strong leadership creates high-performing Teams operating in Value streams, which consist of products, marketing, comms, Design, Innovation, Digital Branding, Development, measurement, DevOps and cyber Security.

    He has deep knowledge of the pre-listed modern disciplines required to execute those £m00 programs to achieve the highest ROI & highly satisfied customer NPS scores. He delivers changes abiding by the complex regulatory standards banking enterprises must commit to or risk high penalties.

    Jana Lace, Enterprise Agile Coach at Haleon

  • John is a highly experienced Lloyds Banking Group engineering lead who’s both a technology expert and amazing leader of people. John’s also an organiser of React London BYOP, a London-based Javascript meetup with over 1900 members.

    I’ve had the privilege of knowing John for a number of years and his vision for digitally transforming the banking industry has never faltered. John always considers others before making a decision and makes sure changes that are implemented are properly educated and mentored throughout the team.

    My relationship with John has never been stronger and he’s always a “go to” person whenever I need to rationalise ideas or gauge opinion and direction. This in itself is a great indication of John’s leadership experience, as strong and trusted relationships should always be valued.
