Mentors may be contacted via the Slack channel which has been setup for this event. To use this channel, you will need to create and account and login. You can create a private chat but, if you prefer, you may email the mentors directly. If you choose to email directly, please post in the Slack channel that you have done so. The mentors are monitoring the Slack channel more closely than email and will need to be prompted to look for your email message.

The following mentors will be onsite for the duration of the hackathon:

Adwait Joshi - Email


Adwait, as his name suggests is a truly unique individual. The Adwaita philosophy by the world guru Adi Shankaracharya, defines Adwait as a non-dual (no one like him exists in this universe), this is especially true if you know Adwait, his creativity, passion and personality is quite addictive and makes a long lasting impression on anyone who crosses paths with him. 

Adwait was not only a straight A student in school but was always interested in business opportunities, from simple projects like collecting a group of kids from the neighborhood and building lanterns to set up a sugarcane juice stand, he was always the leader. When he was 15 years old he won a scholarship and learned C++. This exposure made him start his first company at the age of 15, AD’s Computers, was extremely profitable and paved a path for Adwait’s future; not only giving him the right exposure but also making enough money to pay for his education. While at University at Buffalo, Adwait’s thesis on Visualization Techniques for Anthropometric Data made the concept of Universal Design easy and became a very important part of UB’s research for the next 10+ years. One might say Adwait has a midas touch because whatever he touches turns into gold. Just out of a passion for music, he started a 501c3 in 2004 which has grown to be the largest resource for Indian Music on the entire Internet. Under his leadership this organization has created a strong platform with 40,000 registered members from 140 countries.

Adwait’s IT career in the US began with Fisher Price where he spent his summer creating tools for mechanical engineers to speed up design of toys and he was successful in automating a lot of trivial tasks. He then went on to work at Intel where he was given a challenge that had not been solved before, migrating a 3d visualization software to a 64-bit architecture. He not only took that challenge, but tenuously worked towards finishing the project and won an award for doing it 4 weeks ahead of schedule. That’s when Adwait found his passion for IT, and it was simple to create solutions to automate tedious manual processes.  He believes in the philosophy of complex problems can be solved with simple solutions. For more than a decade now, Adwait has been working with various verticals solving their Data problems. He has tremendous expertise in big data and analytics. After a successful exit in 2016, he is back in the startup mode. His latest venture DataSeers, is a startup focused on RegTech and helping FinTech companies with Reconciliation, Compliance, Fraud and Analytics. The product has been so majorly successful that within the first year the company is already profitable and winning awards. LexisNexis recently awarded DataSeers an Award for creating a truly unique solution in the market space that uses HPCC Systems.

Gurjot Kaur Bandasha - Email


“What you do today defines what you will be tomorrow” has been the driving force for Gurjot.  After completing her Bachelors degree, she worked in the banking sector for about 1.5 years. Though it was a short tenure, her extraordinary abilities of technical delivery and intellect, gained her a “Star Performer Award”. 

Gurjot always had the zeal and desire to learn, grow and excel in not just her domain of work, but in a broader spectrum of the IT landscape. Following her dreams and ambition, she went ahead and pursued her Masters degree in Computer Science. This was one of her crucial career milestones that marked the beginning of her scintillating IT Career in the US.

Post graduation, she embarked on her first full time engagement with a startup – ‘MTS’ as a Database developer. She was a lone warrior in her firm where even without the required guidance or path-setting from a mentor, she strived and set her own growth path, envisioning where she wants to be after a decade. The MTS leadership appreciated her for expert handling and delivery of a critical and time-sensitive project that went on to generate notable revenue and credibility for the firm. In simple words, she is one of her kind who make their own fortune by endless commitment, hard work, persistence to succeed, and most importantly, a never-give-up attitude.

As the next step of advancement, she took up a golden opportunity and teamed up with DataSeers, where she is getting to work with esteemed masterminds such as Mr. Joshi (Adwait)

At DataSeers, she has continuously been shifting gears and working in multiple capacities, contributing immensely towards the firm’s initiatives and engagements. She absorbed the learning curve in a short span and making strides being a big data developer in ECL and gaining momentum on HPCC Systems platform. 

With the pace of learning and grasping abilities that she showcased since the start of her professional career, she has today worked her way up to the ability of managing projects and teams and successful in-time delivery. She received notes of appreciation from her clients that stand as milestones to her impeccable work ethic.

Learning is a never-ending process in life. She respects it and aims to continue learning and acquiring further more capabilities, credentials, valuable technology knowledge, and ultimately, the wisdom to life a complete life. Knowledge is power!
