Senthil Paramasivam, the CEO on the SQL mentor list

A job interview can turn a perfectly competent person into an amateur magician: produce the answer, conceal the machinery, hope for applause. Latha Kandasamy remembers a rather different experience with Senthil Paramasivam. Faced with a challenging problem, she reached a logical solution. What stayed with her was the panel’s interest in the route she had taken.

Paramasivam, her manager Biju Rajesh and HR colleague Miruthu Bashini wanted to understand her thinking: how she approached the problem, broke it into parts and worked through it. In Kandasamy’s recollection, the experience became a lesson she carried into her subsequent work. The answer mattered. So did everything that made the answer possible.

It is a useful place to begin with the co-founder and chief executive of Nallas. Executive titles tell you who can approve a decision. An interview remembered years later tells you something about the attention a person brings to the room. Here, the attention was on reasoning, a subject that runs through Paramasivam’s professional life, from mathematics and database work to mentoring young programmers.

“how I approached the problem”

A mathematician’s route into the machine room

His education took place at St. Joseph’s College in Tiruchirappalli, commonly called Trichy. His qualifications span a BSc, MSc and MPhil in mathematics, together with a postgraduate diploma in computer applications. The sequence runs from undergraduate study beginning in 1989 through postgraduate work in 1994 and 1995. Mathematics and computing share the page in his education long before cloud services enter his job titles.

There is something pleasingly unfashionable about that combination. Mathematics asks for the steps. Computing eventually asks whether the steps work. A beautiful explanation has limited social standing in front of a machine that refuses to execute it. Paramasivam’s later career would be spent in work where structure, performance and reliability were daily professional concerns.

His early roles included systems engineering at Zylog Systems India and SQL Server database administration and architecture consulting at Deloitte. A subsequent consulting assignment at Microsoft involved Tier III SQL Server support. The titles are technical and specific. They place his background close to the practical business of keeping databases useful, rather than at a comfortable distance from the machinery.

His consulting history also records returning to institutions in different periods. At Bridgewater, the earlier database administration assignment ran in 2008 and 2009; the later operations and migration assignment ran from 2015 to 2017. That distinction is worth preserving. A career described only by company names loses the changing work inside them. Administration, support, architecture and migration each ask something different of the engineer, even when the database technology remains familiar.

Other assignments included GEICO, PwC, Idaho Power and Bridgewater Associates. His Bridgewater work included database administration and, later, database operations and migration. Across those engagements, SQL Server remained a recurring speciality. Before he was responsible for the whole company, his professional vocabulary already included the infrastructure on which other people’s work depended.

The chief executive who still appears under SQL

At Nallas, Paramasivam’s work has included leadership of data and analytics and SQL Server to cloud consulting. Today, the company identifies him as co-founder and CEO. Alongside him is co-founder Vangili Palaniappan, whose current responsibilities cover strategy and product management. The business brings together data, cloud, application, quality and generative AI engineering.

Nallas’s own delivery framework, ValueScope, makes project visibility part of its proposition. It includes scoreboards for progress, risks and quality, alongside a business outcome tracker. The company also describes internal hackathons and learning communities organised around technologies and practice areas. These are organisational arrangements, rather than personal anecdotes, but they help explain the environment around its CEO: a services business whose published approach gives space to feedback, shared learning and the examination of work in progress.

The change in responsibility is considerable. A database assignment has a defined technical centre. Running a services company brings recruitment, delivery, client relationships and commercial decisions into the same frame. The connection between the two becomes visible in an unexpected place: a student coding initiative called Codozzle.

There, Paramasivam appears among the technical mentors as “Senthil”, the SQL expert. No elaborate executive introduction is required. Python, Java, data, quality assurance and .NET have their own named mentors. His place in that group is tied to the craft he knows. A chief executive’s title can be quite a large hat; on this page, there is room for the working tools beneath it.

Codozzle brings student programmers together around problems, collaboration and contact with industry professionals. Participants can work on business challenges, share questions, strengthen their skills and compete for recognition. The initiative also offers a chance to work with Nallas. Its design connects learning with the possibility of employment, making the passage from college exercises to professional work a practical concern.

That gives the interview recollection a second setting. Kandasamy remembers having her reasoning examined by a panel. Codozzle gives students a place to practise reasoning in company, before a hiring conversation begins. The two episodes sit naturally beside each other: a candidate explaining her approach, and a mentor listed by the particular discipline he can help others understand.

Trichy remains in the conversation

Paramasivam’s association with education extends beyond the coding community. St. Joseph’s College lists him among its industrial experts on the academic advisory body. A December 2023 mathematics Board of Studies document also names him, then with a technology leadership title at Nallas. His college connection therefore includes a formal professional role alongside his own years of study.

Advisory lists are rarely accused of theatricality. Their interest lies in the relationship they record. Here is someone whose education included advanced mathematics, whose career moved into enterprise databases in the United States, and whose name appears again in the academic life of the institution where he studied. The connection is concrete, even without a grand speech attached to it.

His professional base is Stratford, New Jersey. Nallas also has an operating presence in Coimbatore. His Indian directorships add dates to that cross-border working life: Nallas Software Solutions appointed him a director in October 2018, and Nallas Technologies India in July 2023. These are separate corporate appointments, each a specific point of responsibility.

The geography matters because it keeps the story from shrinking into a single office. New Jersey, Coimbatore and Trichy each have a different place in his professional record: current base, company operations and education. His activities with students sit within that same geography, connecting the business he runs with people preparing to enter the field.

A lamp, a new intake and an old question

On August 21, 2025, Paramasivam was chief guest as Jansons Institute of Technology welcomed its seventeenth intake of students. The setting was the Padmam Auditorium. The ceremony included Tamil Thai Vazhthu and the lighting of the Kuthuvilakku, the traditional lamp. Photographs show him taking part in the lamp lighting and receiving a memento.

His address concerned embracing innovation in the digital age. For the students, it was the opening of an engineering education. For the visiting executive, it was another appearance at the point where education meets working technology. The ceremony’s traditional form and its digital subject made an agreeable pair. A brass lamp requires no software update to perform its part.

College appearances can easily disappear into ceremonial language. This one belongs beside the more practical details: a named SQL mentorship and an academic advisory position. Together, they show repeated participation in settings where students encounter the profession. The speech, the mentoring and the committee listing are different forms of that contact, each with its own demands.

The AI conversation returns to the data

By 2026, the conversation around Nallas had expanded further into enterprise AI. The company announced Paramasivam’s planned attendance at the Databricks Data + AI Summit in San Francisco, scheduled for June 15-18. Its stated themes included data modernisation, AI readiness and turning information into intelligence that organisations could trust.

Nallas’s Databricks consulting work includes migration from SQL environments to lakehouse architecture, governance through Unity Catalog and generative AI proofs of value. For a leader with a SQL Server background, the connection is easy to follow. The platforms have changed; the work still concerns organising information so that a business can use it responsibly and effectively.

An October 2026 Nallas article develops that company position further. It argues that moving AI into dependable production requires attention to the architecture beneath it: timely information, context, controlled access and traceability. The argument belongs to the company’s published thinking. It also gives a clear picture of the market in which Paramasivam now leads, where database engineering and AI implementation meet.

That is a substantial distance from an individual support assignment, though the technical concerns remain recognisable. Information must reach the right place. Its meaning must survive the journey. Someone must be able to explain what happened. Enterprise technology has acquired more ambitious nouns, while retaining a considerable appetite for careful verbs.

Return, finally, to the interview. Kandasamy remembered the attention paid to her thinking, and credited Paramasivam and his colleagues with helping her approach challenges more deliberately. It is a modest episode beside the corporate titles and conference agenda. It is also a revealing human detail: someone had an answer, and the people across the table took an interest in the working.
