I would describe myself as a full stack developer (Grails, Groovy, Java, Spring, Hibernate, jQuery, SQL). With over 12 years of experience in small and large companies, I am the solid foundation on which companies can build on and I tend to elevate my co-worker's proficiency to new levels. I am at my best when I work very closely with 'business' and materialize their vision, with the help of my technical team, in the simplest and most efficient way.I currently work at 99dresses, an app on which women buy, sell and trade clothes. I have been there for 1 3/4 years and in that time, we built and released 17 versions of 99dresses, pivoted 4 times and released a couple of versions of 99onesies (the kids' version). 99dresses reached a moderate success, 80,000+ women signed up and 30,000 items of clothing were exchanged. We also received 175+ reviews on the app store, averaging 4 stars.As the Co-Founder/CTO of 99dresses, I was leading our team of 5 in terms of product development and delivery. I designed and implemented the backend (domain, services, API used by the iOS apps) as well as public facing web pages and admin web pages necessary for operations. I also integrated with 3rd party APIs for payments (Stripe,) shipping (EasyPost) and Metrics collection (MixPanel). In addition to the development tasks, I provisioned and maintained the database and app server environments (AWS), from test to production. I also performed all database migrations, across new features and 3 notable pivots. Finally, I instated continuous delivery practices (automated tests, Jenkins) and feature/bug tracking (JIRA).
