use-cases. Meta is a multinational technology conglomerate that owns and operates Facebook, Instagram, |
Threads, and WhatsApp, among other products and services. It is one of the ten largest publicly traded |
corporations in the U.S. and is considered one of the Big Five U.S. information technology companies. Before my |
leadership role with Meta, I was a Vice President with Goldman Sachs in Salt Lake City, UT and a Manager, |
Machine Learning with Dell in Phoenix, AZ. My career has spanned more than a decade and has centered around |
building distributed systems and scalable machine learning. Areas of expertise of mine include software |
engineering and management, cloud architecture, big data management and strategy, data security and |
management, and continuous deployment and integration. |
In addition to my experience, I am well-educated, holding a Master of Science degree in Business Analytics and |
Project Management from the University of Connecticut School of Business and a Bachelor of Technology in |
Computer Engineering from the National Institute of Technology Karnataka in India. |
Based on my more than decade of experience in the industry and high level of education, and my observation of |
Mr. Tiwaris career, I am expertly qualified to speak to his extraordinary ability in digital banking and financial |
services. |
First, I am aware of Mr. Tiwaris participation as a judge of the work of other professionals in the field through his |
participation in the Expert evaluation committee at Meta for validation and evaluation of generative AI (Artificial |
Intelligence) applications across Metas payment products and payment settlement systems, as they released |
llama and llama2 models. Mr. Tiwari evaluates the underlying variable, development architecture and domain |
policies of the AI models across Payment applications. His deep understanding of Payment flows and associated |
dependencies helps Meta make decisions on associated changes and choices around model specific choices. He |
had been part of the evaluation committee for last 2 years. |
I am also aware of Mr. Tiwaris membership in Metas AI for Payments Panel, an organization in the field that |
requires outstanding achievement of its members, as judged by recognized national or international experts in |
their field. |
Mr. Tiwari has an exceptional reputation in the industry, as evidenced by his participation as a judge of the work |
of others in his field and his membership in an organization that requires outstanding achievement of its |
members . There is no question in my mind that Mr. Tiwari is an individual who has risen to the top 1-2% of |
experts in his field. His unique contributions to digital banking and financial services on a widespread scale make |
him a critically important source of change and disruption in the field. He personifies an individual of |
extraordinary ability and I wholeheartedly endorse him for that visa classification. |

Dear Sir/Madam |
RE : Sid Tiwari |
Sid let me know that he is applying for a green card, and I am writing to provide some input on his expertise. |
I have known Sid for a number of years, our first meeting being several years ago when we were petitioning various |
companies for expertise on a "payments platform of the future. Sid was clearly the expert on the McKinsey team and |
gave multiple presentations representing his company on how to imagine such a platform. Sid was clearly an expert |
in the realm of the payments ecosystem. He has had a good amount off experience in consulting, banking and |
technology, and is able to offer advice and expertise on building or improving service offerings, using a set of |
financially and regulatory compliant and innovative solutions to ensure that the product offering is cutting-edge and |
controlled in all the right ways. |
My name is Debra Ameerally, and I am currently a director on the AIML organization at Apple Inc. I have previously |
worked in Payments for several years here at Apple. I am a seasoned e-commerce professional, with broad expertise |
and experience in online commerce, including analyses and strategy, with a strong IT background in large corporate |
systems. |
I would not hesitate to recommend Sid as a thought leader in the field of payments/financial services/digital banking. |
He is very capable and leaves no stone unturned once he dives into a project. He thinks through all aspects of a |
problem to provide the best long-term solutions. |
On a personal note, I have always found Sid to be an upstanding character, with lots of integrity and a kind and |
generous nature. He has become a great friend. He would be an asset to any community. |
Please do not hesitate to let me know if I can answer any questions for you regarding Sids work with us. Much of our |
work is confidential, but I may be able to answer at a general level. You can contact me by email or phone; I attach |
my contact information in the signature below. |
