Who are we:
While we are a diverse set of people, we value the following core traits:
- Fast learning: We often require learning new tools and technologies. We believe in adopting them if they are particularly well suited for our problems, instead of limiting ourselves to what we already know. However, we are always short of time and therefore have to learn fast.
- Versatility: While each one of us has a core skill, we possess at least one secondary skill as well. Apart from allowing the team to be fluid, it also helps us understand how all pieces (frontend, database, network, servers, etc.) fit together.
- Madness about quality: Put together, individual lines of code should be robust, scalable, high-performance, fault-tolerant, and most importantly, beautiful software. We also stay up-to-date with the latest in the world of software to make ourselves better.
- Passion: To try out new ideas and iterate on existing product features, and love experimenting with new technology if it's right for the job. Because not only do we ride the cutting edge, we make it happen.
- Collaboration: We believe that engineering is a continuous process of learning and improvement and that the best way to learn is by getting help from your fellow engineers. Coding is more fun when you do it together and appreciate the feedback.
