Rhisiart has excellent experience in writing android apps to a very high quality. He is a dedicated professional developer and a pleasure to work with. I would recommend Rhisiart to any team wishing to develop Android apps to a high standard.
Rhisiart built an Android app for The Wildlife Trusts. This was a major software project which included thousands of records of nature reserves and integration with data feeds to display events. We are pleased with the result and it has received some excellent early feedback from users. Throughout the development Rhisiart demonstrated initiative, creativity and perseverance. Recommended!
I've worked with Rhisiart in his capacity as a Java Developer on some very high-profile projects at IBM/DVLA. I found him to be exceedingly capable and adept in multiple disciplines. He exhibits great communication skills when dealing with people and teams be they internal, outsourced or supplier and is excellent at motivating others. Rhisiart demonstrates a great depth of understanding technically, spending the time to understand the full scope of his solutions and finds achievable, quality, and efficient routes to delivery. He is as skilful as he is personable and always gets the job done. I would be more than happy to work with Rhisiart in the future.
I have known Rhisiart for approx 10 years wherein the main he has been a lead Java developer working on complex business systems. His work has been without equal and I could always depend on him to meet challenging deadlines without compromising quality.
I worked with Rhisiart for several years whilst I managed an applications development programme of work and Rhisiart was a J2EE applications developer. He performed a several key J2EE applications development roles, most notably on a mission-critical high transaction web application, bringing both java experience and business knowledge to bear in developing and refreshing an extremely valuable (revenue-generating) website. In this role I found Rhisiart dependable and committed and a key member of the team in bringing continuity across numerous releases. It was a pleasure working with Rhisiart.
Rhisiart is one of the most knowledgeable and competent developers I have worked with as a Tester and Test Manager. He is extremely conscientious and always takes the time to fully understand the requirements of the product on which he was working. As a result, the code he delivers can always be relied upon to be of high quality with extremely low defect rates. He is approachable, helpful and always willing to share his knowledge and expertise with others. It has been a pleasure working with Rhisiart and I would highly recommend him.
Rhisiart is a very capable and conscientious developer who can work unassisted or as part of a team on challenging projects. He was central to the development of some key applications on the DVLA projects I was involved in. I found his approach very professional with a keen eye for detail and is calm when faced with difficult or frustrating circumstances. I would recommend Rhisiart to any company without hesitation.
Rhisiart worked for me on several occasions during complex JEE Integration projects. He is an outstanding developer who thrives on producing elegant efficient solutions. He quickly became the backbone on the team. In additional to his immediate responsibilities, Rhisiart would coach the less experienced team members and assure their work. His meticulous attention to detail speaks for itself in the exemplary quality of his deliverables. If you seek a highly capable senior JEE developer/designer you need look no further. Highly recommended and a pleasure to work with!
