In working with Jamuna over the last two and a half years, I have seen Jamuna grow as a leader by managing several complex development projects while also returning to school and obtaining her PMP certification on the first attempt. Her ability to multitask as well as lead a project team truly caught my attention. Also while assigned to my team, Jamuna has been recognized by VA as one of the Subject Matter Experts (SME) for Section 508 Conformance. Jamuna continually strives for perfection through every work task that has been assigned. I have had the great opportunity to also learn from Jamuna.
I could write pages about the invaluable contributions that Jamuna made to the team and as an individual but I only hope this recommendation suffices to let her know how incredibly impressed I have been and remain with her. For the sake of space I would like to focus briefly on the 18 months that she worked on our project at the Veterans Health Administration. During that time she made innumerable contributions that directly impacted the success of the project and the team itself.
Jamuna was a hardworking employee who contributed greatly to the project team. She was insightful, enthusiastic and accomodating. She could always be counted on to deliver what was needed in a timely fashion. Furthermore, her maturity in dealing with team mates and customers alike, was a valued commodity on a project where continuous interaction with stakeholders was required. She also continually worked to refine her trade, and bring to the project what was needed to accomplish tasks as they arose. I would certainly turn to Jamuna as a top choice on any development team I was building.
I have known Jamuna since 1997 (Both personally and professionally). She is a smart, dedicated individual with a very positive attitude. Her commitment to whatever she puts her mind into is truly amazing. She is an achiever and I wish her all success. I will be happy to be work with her in future.
Jamuna is is a seasoned project manager with strong industry knowledge in health care and public services. She takes pride in her work, motivates her team and gets the job done. In particular I was impressed with Jamuna's excellent communication skills, demonstrated in many formal and informal meetings with government clients. Additionally, her rational and level-headed approach to solving difficult situations have been very beneficial. I had the pleasure of working with Jamuna for two years. Not only is she leading by example, but also a kind individual with a great personality. Jamuna would make a great addition to any team.
Jamuna is an extremely skilled, proficient IA. She is conscientious and
analystical in all her work, resulting in the best possible solution delivery.
She quickly grasps and understands systems and fucntionalities; this allows her
to come up to speed quickly.
