When you ask Vathsala Periyasamy about her work, she does not begin with abstractions about technology or sweeping predictions about artificial intelligence. She starts with a practical proposition about how technology can be used to strengthen human systems rather than overwhelm them.
In an industry grappling with increasing regulatory pressure, cybersecurity threats, and operational inefficiencies, Periyasamy has carved out a path marked not by declarations but by demonstrable impact. At Hexaware Technologies, where she serves as an IT Project Manager and Senior Technical Architect, her work has changed how financial organizations handle compliance and risk management. Perhaps more importantly, it has changed how they operationalize these processes.
Building Stronger Foundations for Compliance
Compliance in the financial sector often resembles an arms race against complexity. New regulations, tighter reporting requirements, and an unrelenting demand for transparency pose daily challenges to institutions. Most organizations, faced with these challenges, adopt temporary fixes.
Periyasamy follows a different method. She focuses first on foundational integrity, structuring data pipelines, optimizing data engineering workflows, and ensuring that systems remain audit-ready from inception. While leading key initiatives for Fannie Mae, she redesigned how critical mortgage data moves through systems. This strategy changed previously fragmented, manual systems into cohesive, automated processes that strengthened compliance responsiveness.
"You cannot automate trust," she says. "You build it at every layer, from how you engineer your data to how you validate your algorithms."
According to a 2024 McKinsey & Company survey on financial institution priorities, 68 percent of executives identified regulatory compliance as one of their top three business risks for the coming years. This growing emphasis on compliance underscores why Periyasamy's work proves timely and consequential. Institutions that once treated compliance as a defensive burden are now beginning to recognize it as a strategic foundation for operational resilience and trust-building.
Creating Better Risk Management with Practical AI
One of Periyasamy's most notable achievements is her leadership in developing a generative AI-driven tool designed to read and analyze home loan documents to detect fraud.
Unlike many AI risk models, which prioritize speed over transparency, her design prioritizes both aspects. Developers built the system on cloud-native frameworks and integrated it with robust cybersecurity protections. The system improves fraud detection accuracy while maintaining full explainability and auditability, which represent critical requirements in today's regulatory climate.
"When you deal with financial data, it is not enough for the system to be smart," Periyasamy explains. "It must also remain accountable. Otherwise, you have simply replaced one vulnerability with another."
The impact appears tangible. Mortgage review times have decreased significantly. Fraud detection has become faster and more accurate. Compliance audits proceed more smoothly. At a time when organizations increasingly embed artificial intelligence in risk functions, Periyasamy's work exemplifies how thoughtful integration can offer institutions both efficiency and defensibility.
Publishing Knowledge Beyond the Corporate Walls
Beyond her corporate achievements, Periyasamy extends her knowledge into the broader conversation about technology's role in public life. She has published in respected platforms such as Field Technologies Online and Global Banking & Finance Review. Her articles focus on themes like event-driven cloud computing for government agencies and the responsible deployment of AI in financial services.
Her work highlights the practical applications of emerging technologies, striking a balance between technical depth and a pragmatic focus. This commitment to grounded discourse reflects an understanding that the societal consequences of technology adoption matter as much as the operational benefits.
Recognition without Spectacle
Although she discusses them with characteristic humility, Periyasamy's achievements have earned her recognition. In 2024, she received the Bronze Globee Award in the Women in IT category. She holds positions as a Senior Member of IEEE and a Fellow of the British Computer Society. These distinctions quietly affirm her standing within the global technology community. In September 2023, she reached a significant milestone by becoming an Institute of Electrical and Electronics Engineers (IEEE) CertifAIEd Authorized Assessor, achieved by very few in the industry.
She clearly states that such honors serve a purpose beyond personal pride.
"Recognition becomes meaningful only if it propels you to raise your standards further," she says. "Technology does not stand still, and neither can we."
Her continuous improvement philosophy mirrors the qualities that financial systems themselves need to cultivate.
The Broader Lesson: Integrity in an Accelerating World
In today's financial technology sector, there is a pervasive temptation to prioritize velocity over substance and to adopt new tools without thoroughly examining their risks.
Vathsala Periyasamy offers a different model. Her work reminds us that sustainable development requires more than clever code. It demands the discipline to build responsibly, the insight to engineer for resilience, and the humility to recognize that technological power carries ethical obligations.
As organizations embed artificial intelligence more deeply in finance, compliance, and risk management, the need grows for leaders who balance speed with accountability. During these changes, Periyasamy's career clearly indicates that the most significant transformations stem from thoughtful engineering, secure practices, and enduring human values at their core.
