Little did I know that this experience would be worth a thousand courses that I could have taken on any platform. Sometimes I think what if the lockdown had not happened.
This story might be demoralizing for some people, but I think I just need to blab this out to the world. Also, I hope my family doesn't read this, there are things I haven't told them in here.

Karn is an extraordinarily talented, diligent and foresighted individual. He is gifted at building products from paper to code, and has a knack of finding efficient solutions to complex problems.
In my experience, I have rarely seen such a mixture of talent and passion put together. At InterviewReady, Karn exceeded our expectations.

Managed me at SendX
Karn is an amazing developer with an extremely good work ethic and eye for executing pixel perfect front end work.
He has endless potential and is truly a joy to work with. Iβd highly recommend him to anyone lucky enough to work with him.
CEO, SendX & SendPost
Managed me at SendX
Gyan interned with SendX and SendPost for around 6 months. He is a very strong full-stack engineer who can create pixel perfect frontend while being able to work on backend pieces sending millions of emails per day. He is a quick learner, a great team player and, has a very strong work ethic. You can rely on him that things will be done with utmost quality. He also has pretty good product instincts and can think from the user's perspective.
During the internship, he grew tremendously and his impact was visible to everyone in the company. It was a great experience working and learning from him. I hope to work with him again in the future. If not, I will be sitting on the sidelines, cheering him and watching products he builds in the future.
CTO, SendX & SendPost
Worked together at Customer.io
Karn is a role model for drive and growth. He is a spark that inspires the rest of the team. I've worked with Karn on numerous projects over my time at Customer.io and was consistently impressed with his ability to turn an idea into a prototype with minimal direction.
As a product designer, you dream of working with engineers who have a strong product sense. Engineers who understand that the end experience is the source the truth. Engineers that don't need a red-lined design file. Engineers you can trust to make a decision themselves instead of waiting on one. Karn is one of those engineers. That type of engineer keeps the energy and momentum up for the whole team. It ultimately leads to a better outcome for customers. Any team would be fortunate to have Karn on their team.
Product Designer, Customer.io
Worked together at Customer.io
I've had the privilege of watching Karn grow from an eager, fast-learning newcomer into an absolute powerhouse of an engineer. He thrives on challenging projects, he improves every area he touches, and he keeps quality, maintainability, and scalability in mind with every change. I've loved and benefitted from his partnership and initiative on seemingly improbable projects, valuing his passion and ability to pitch approachable and thorough solutions, refining them with senior tech leaders (including our CTO!), and delivering them with ease and confidence.
Beyond his technical skills, he brings a contagious energy, deep curiosity, and genuine empathy for both customers and teammates. An early adopter of new technologies, he freely shares knowledge, ideas, and insights and inevitably elevates any team fortunate enough to have him.

Worked together at Customer.io
I had the pleasure of collaborating with Karn as part of the In-App squad at Customer.io. Together, we worked closely with the Content team to implement In-App templates and successfully refactored the entire In-App message creation process using Customer.ioβs main visual editor, built on top of Parcel.io.
Karn is an exceptional engineer with an impressive ability to deliver results at a remarkable pace. He led the initiative, coordinating efforts across multiple teams to enhance the In-App message creation experience significantly.
It was a privilege to work alongside Karn, and I strongly recommend him to anyone seeking a talented, efficient and highly capable teammate!

Senior Platform Engineer, New Relic
Mentored me at Google SPS
I worked with Gyan when he, along with three other members joined Google Software Product Sprint. Gyan is technically pretty sound, and he showed great maturity in designing and implementation. He has very impressive webpage development/frontend skills and he can make websites look very very professional almost effortlessly! He was eager to learn new things and was never afraid to take on challenges. I want to wish Gyan all the best in all his future endeavours, and he always shows up to be a great contributor.
