About Us

We’re run by developers for developers focused on React, React Native, and Node.js and we believe that specializing in a few tech stacks allows us to go deeper into the nuanced details of each language and framework we vet for. We practice transparent vetting which means every time you want to hire a developer we’ll send you a detailed technical profile of that developer which includes their score matched to the rubric they tested for, a recording and score of their tech interview, and the code they wrote for our challenge.

For Puzzle, the experience of each collaborator is unique. For this reason, we care about providing them experiences that increase their commitment and promote the agility to adapt to changes.
We know that having more committed collaborators represents an increase of up to 21% in profitability, and 17% in productivity and that currently the
74% of the main companies in the market use agile tools and processes









Specialization matters

We’ve found that by focusing only on specific tech stacks we are able to drill down into the tiny details about what makes each developer great. This is why we only serve a few tech stacks at a time.

Remote work is the future, now

We can’t imagine a world without remote work because we live it daily, working from the comfort of our homes or co-working spaces. We want to see this pushed forward so that one day soon remote work would just be referred to as work.

We operate on grace & kindness

We harp on grace because we don’t think treating people well stems from someone earning it. Instead we seek to be kind to others even on their worst day. Kindness means we celebrate others successes & we speak the truth in a gentle way.

Health is the foundation of good work

Without health we have nothing so we encourage team members at Hirepuzzle to make time for physical, spiritual, and emotional health each day.

We never want to leave our roots of serving the open source and development community as a whole. We’ll continue to hire team members that understand this vision, continue listening to what the community wants, and continue funding open source efforts.


It’s easy to think about being generous “once we’ve made it.” Instead, we are focused on the journey rather than the destination and that means we’ve committed 10% of our profit towards our two main mission fields; the open source development community and street kids in Kenya.
