What people say

Ashwanth is extremely knowledgeable and an awesome leader with an incredible ability to motivate his team to perform at their best. He is an absolute powerhouse with an amazing amount of energy and industry knowledge. He is very friendly and always enjoys mentoring and helping many engineers around him with his deep technical expertise and leadership skills. He is always focused on what he does and loves solving complex engineering problems creating scalable creative solutions. Ashwanth is an absolute joy to work with.

Ramesh Periyathambi
Distinguished Engineer, eBay

I have seen Ashwanth as a great individual contributor with stellar leadership skills. Being a strong coder he was extremely productive by contributing a ton of code to the Search Experience Service and Search Backend code bases. His ability to convince leadership and senior architects on his strategy and design is noteworthy. Junior engineers in the team also constantly looked up to Ashwanth for advice.

Praveen Athmanathan
Engineering Leadership, ShiftSmart

I know Ash as an excellent mentor and highly experienced engineer. When I was a newbie in the company, he helped me to navigate through the technical and subtle cultural aspects of the organization. Pragmatic learnings from him rocketed my onboarding process enabling me to start quickly delivering value for the company at full speed!

Dmitry Paramzin
Java Software Engineer, Canva

Ashwanth is one of the best engineer + leader employees I’ve had the honor to work with in my career. He not only adds value through his excellent coding, design, and automation skills, but also increases the impact of the team through code reviews, technical designs, and mentoring. Within a year of joining my AI team at NPD, he came up with a framework that reduced our testing and validation time from days to mere minutes and then open-sourced the framework. He also developed the framework + ecosystem to enable deterministic dialogs in ShopBot’s AI in a matter of minutes, something which had taken months in the past and was a major obstacle to our build to production cycle. I have enjoyed having Ashwanth on my team and have learned a lot about engineering simplicity and agile development from him.

Amit Srivastava
AI Executive, ServiceNow

Ashwanth has a serious blend of technical and leadership skills. I have seen him be a mentor to many developers and he has a natural way of advising the decisions and compromises one should make around coding and architecture of a system. Based on his experience, he can master any skill pretty quick and so I highly recommend him for senior roles in technical projects.

Ravindra Bhanot
Software Engineer, Meta

Ashwanth is a very talented engineer, who delivered and helped my team deliver many crucial projects into production. What is most noticeable in him is the ability to explore new areas and become proficient or even an expert in them in a very short span of time. His knowledge and practical experience with ecommerce software, deep computer science background and ability to think on the ground was crucial to engineering organizations like ours. He has single-handedly developed software that affected a huge code base with almost zero issues in production, fixed many critical issues in production and worked in a team setting to help meet a deadline with great quality and he has delivered brilliantly on all fronts. I wish him all the very best and look forward to working with him in the future.
