Dedicated to continuous learning and knowledge sharing

Hunger for more drives us. Sometimes “the more” is to write code efficiently, in less lines. Sometimes it is to learn completely new programming language. Our team members know that achieving success takes lots of learning and self improvement. It does not take much time to step-up to the next level once you join Sentinel. Working on complex products and apps, tackling difficult challenges in search engine marketing and lead generation, sharpen your skills in record time.

As much as we believe in learning, we equally believe in sharing and passing the value to the community. Our team members are IT University lecturers, bloggers, they are frequent speakers on events and conferences on design, UX, social media, SEO & PPC, and web development.
