I've been in a startup for over two years. I lead/manage a team of six engineers. I was key engineer on the Insights product, which is a nice mix of APIs and complex queries to a Postgres database.
Previous to that, I developed several Web applications in financial domain; using PHP with Zend framework (and doctrine for database abstraction). Before that, I coded tools used in a genetics lab, such as MaggotTracker, and as co-developer of the QuantWorm suite for quantitative phenotyping of C. elegans.
