In an ecosystem, if financial institutions struggle to communicate with each other, every transaction seems like a slow, clunky process across the countries. According to Fortune Business Insights, the global FinTech market was valued at around USD 257.3 billion in 2022 and is estimated to rise to USD 882.3 billion by 2030. In spite of this massive growth, many banks, brokers and financial institutions struggle with a nagging problem of fragmented systems that make reliable, fast and seamless data transfer a distant reality. Here comes into picture, the API economy, an idea that promises to stitch these disjointed systems together. One expert who has brought a change in this landscape is Vishal Sharma, whose work in developing API ecosystems is solving global industry problems from retail to banking, aiding societal progress at large.
Our present day financial services industry faces a thorny challenge of legacy systems. Many banks and financial platforms rely on outdated infrastructure, mainframes that hum along reliably but struggle to keep pace with today’s digital demands. These systems often operate in silos, making it difficult for institutions to share data with partners, onboard clients quickly, or deliver real-time services to customers. Adding to these hurdles is the growing pressure for security, where the average cost of a data breach in the financial sector was $6.08 million in 2024, 22% higher than the global average breach cost of $4.88 million, per IBM report. Without a unified way to connect systems securely, institutions risk falling behind in a world where consumers expect quick, personalized services, whether they’re checking investments or transferring money across borders.
To tackle these challenges, Vishal Sharma built API ecosystems that act like digital connections. At one major financial institution, he led the charge to develop a comprehensive API framework, including a gateway to manage traffic, robust security protocols to protect data, and a developer portal to make integration a priority. Before his approach, external partners had to deal with complex, resource-heavy processes like Mutual TLS (mTLS) to connect with the institution’s systems. mTLS is a legacy pattern that results in longer client onboarding. Vishal’s efforts served as a catalyst for change, with a centralized API gateway that streamlined connections, enforced consistent security standards, and reduced onboarding times.
“The goal was to make integration as simple as plugging in a USB drive,” Vishal explains. “We wanted partners and clients to focus on their business, not on coping up with our tech.”
This API ecosystem had a vast commercial impact with its secure, scalable integrations, where Vishal’s ideas improved the institution’s digital presence by roughly around 20%, allowing it to attract more clients and partners. For retail customers, this allowed faster access to services like real-time investment tracking. For instance, a small business owner in New York instantly shares financial data with a broker in London, or a retiree in Tokyo checking their portfolio in real-time on a mobile app. These are the kinds of experiences Vishal’s API framework made possible, turning legacy processes into smooth, customer-friendly interactions.
The impact was even greater worldwide, with Vishal’s framework aligned with the rise of Open Banking, a system that is redefining financial services by providing secure data sharing between companies. In Europe, where Open Banking regulations like PSD2 have pushed banks to open their APIs, Vishal’s efforts in standardizing gateway became a blueprint for others. It enabled the institution to integrate with over 275 financial entities across the world, promoting partnerships that powered services like instant payment processing and corporate action portals. These portals, used by banks and brokers with significant combined revenues, gave retail investors and financial advisors a single platform to manage corporate actions, services like dividend payments or stock splits, without juggling multiple systems. This not only saved time but also made investing more accessible to everyday people, democratizing wealth management.
At another leading financial organization, Vishal took API management to new heights by integrating it into the firm’s core strategy. He didn’t just build an API gateway, but championed its adoption across the entire organization, conducting 23 global training sessions that were targeted to reach around 50,000 technologists. More than about tech, it was about changing how teams worked together. Before Vishal’s efforts, different departments used their own APIs, creating point to point systems that slowed collaboration. By standardizing APIs and enforcing governance, he made it easier for teams to share data, launch new services, and integrate with external partners. The result was a payment application that could manage over 2,000 transactions per second, allowing merchants to offer faster, more reliable checkout experiences globally.
Benefiting the retail industry with faster, more secure payment systems meant merchants could process transactions without delays, reducing cart abandonment. This is a major problem, with an average of 70.19% of online shopping carts abandoned across industries, according to a 2025 Baymard Institute report. This resulted in smoother online shopping for customers, whether buying clothes from a boutique in Paris or groceries from a local store. The API framework developed by Vishal also supported Open Banking initiatives, allowing banks to share data with third-party apps securely. This meant customers could use budgeting apps to track spending across multiple accounts or access loans from fintech startups, supporting them to make smarter financial choices.
From the societal context, by making financial services more accessible, his API ecosystems have helped reach underserved communities. In regions like Asia and Africa, where mobile banking is a lifeline for millions without access to traditional banks, standardized APIs support fintechs to deliver affordable services. For example, Vishal’s work on secure API gateways supported platforms that let small farmers in rural areas access microloans or insurance products, encouraging economic inclusion. His contributions also aligned with global sustainability goals, as smooth digital processes reduced the need for paper-based transactions, reducing operational waste for financial institutions.
Not limited to API tech solutions, Vishal introduced a Signed URL pattern for handling large financial files, replacing legacy, resource-consuming SFTP processes. This enabled banks and brokers to share huge datasets, like transaction histories or regulatory reports, quickly and securely. For global markets, this provided faster compliance with regulations, lowering the risk of costly fines. It gave the retail consumers quicker access to critical financial information, like tax documents or investment statements, without the hassle of manual processes. “It’s about removing friction,” Vishal says. “When you make data flow smoothly, you’re not just helping businesses, but helping people live better.”
Vishal’s initiatives earned him a speaking slot at API Days, a leading global conference, and a feature in Digital Asset Serv Magazine. His frameworks have set a standard for financial institutions on how to approach API-driven integration, influencing peers across the industry. By challenging the status quo of siloed, bespoke integrations, Vishal’s ecosystems have paved the way for a more connected, efficient financial world.
As the current financial institutions face mounting pressure to innovate while staying secure, Vishal Sharma’s standardized, scalable frameworks offer a pathway to success. The new-age AI assisted financial services, that depend on real-time data exchange, will rely heavily on robust APIs. His approaches are devised in a way that helps institutions to integrate AI tools seamlessly, providing customers personalized advice or fraud detection without compromising security. For global markets, this implies faster innovation cycles and more competitive services. It promises a future where financial tools are more inclusive, efficient, and sustainable, guiding individuals and businesses alike to grow and thrive in a digital-first generation.
