Don't just take my word for it

Notes from teammates and client stakeholders I've worked alongside.

Had the pleasure of working closely with Sanjiv, and he is an exceptional leader who seamlessly bridges high-level strategy with deep technical execution.
Sanjiv excels in technical problem-solving—when complex, high-stakes engineering or architectural challenges arise, he is the person you want in the room. He approaches problems analytically, quickly getting to the root cause and devising elegant, scalable solutions.
Beyond his technical acumen, Sanjiv is a standout leader in solution delivery and team management. He has a proven ability to align cross-functional teams, streamline processes, and keep project milestones on track without sacrificing quality. His clear communication, structured approach, and genuine investment in supporting team members make him a trusted partner and a pillar on any team.
I highly recommend Sanjiv to any organization looking for a strong technical strategist and reliable leader who consistently delivers results.

Sanjiv is a results-driven leader who combines strong management expertise with impressive technical problem-solving skills.
Throughout our time working together, Sanjiv consistently demonstrated a unique ability to turn complex technical issues into clear, actionable solutions. Whether navigating architectural roadblocks or optimizing workflows, he approaches every challenge with composure and sharp strategic thinking.
As a manager and project driver, he creates clarity out of ambiguity, ensures cross-functional alignment, and drives projects across the finish line on time and within scope. Any team or business unit would benefit greatly from Sanjiv’s leadership and technical domain mastery.

Sanjiv is a very creative person. Initially I thought he was just a simple UI developer but slowly as time passed and we worked together on few projects, I came to know he is much more knowledgeable and skilled person than what he shows. Sanjiv is always in search for doing something different and learning more and more everyday.
When ever I had some problems or I got stuck in something, I found it was very useful to talk to him about it and he always gave me a new perspective to look at it.
Sanjiv, it was a pleasure working with you and shall look forward to work with you in future as well.

This is a first time I am recommending someone on LinkedIn. Because I think I was looking for strong reason to do it for someone. Its now almost 6 months me and Sanjiv are working together with LBi India. Somehow I get jell up with him as both of our career tracks matches with each other. As he and me get in as a UI designer in the industry and now we both are grown good as UI developer and UI designer.
One thing I tempted to recommend Sanjiv is his helping nature and skills to elaborate the solution. He is a good designer but his JavaScript basic and JQuery tricks rocks. And I would like to mentioned that he was the one of the reasons I started taking JQuery seriously. I am always thankful for him for all his great help and knowledge sharing.
