About Me

I am a software product manager and web developer with 10+ years of experience developing and delivering software products for web and mobile applications.

My primary expertise is in full stack web development and I also have extensive experience managing software products and teams according to agile methodologies

I have experience crafting product roadmaps, user stories, wireframes, mockups and prototypes, with the technical experience necessary to work effectively with cross-functional developers both on-shore and off-shore.

I possess full cycle proficiency across strategy/discovery, UX, design, dev, QA and production line management.
