How Ashok Choppadandi's Data Architecture Transformed a $28B Financial Institution
Before Choppadandi's involvement, the bank was grappling with deep-rooted inefficiencies: over 40 fragmented systems across business lines, inconsistent customer experiences, and compliance processes riddled with manual effort. 'The bank had accumulated a patchwork of legacy systems through years of growth and acquisitions,' Choppadandi recalls. 'This created blind spots that affected everything from customer service to regulatory compliance.'
Recognising the urgent need for change, Choppadandi led the design and implementation of a cloud-native, intelligent data ecosystem that would redefine both the institution's internal operations and its external reputation. Built on Snowflake, AWS S3, and Kafka, with business-specific data marts and governed by Collibra and Coalesce low-code ELT tooling, the new architecture was a leap toward real-time, customer-centric banking.
'We designed the system with both current and future requirements in mind,' he explains. 'It had to meet regulatory frameworks like CECL, AML, and Basel III, but also empower agile decision-making and customer personalisation.'
At the core of this transformation was Data Vault 2.0 modeling, enabling a flexible and scalable data warehouse. Kafka streaming pipelines delivered real-time insights across functions, while an ambitious data governance initiative enforced over 1,500 data quality rules and complete lineage mapping.
But perhaps the most pioneering element was Choppadandi's application of Data Reliability Engineering (DRE). 'We treated data platforms as living environments,' he says. 'Our self-healing architecture could detect and resolve anomalies before they affected operations, driving resiliency and trust.'
The results were nothing short of extraordinary. A unified Customer 360 platform enhanced relationship banking, regulatory reviews found zero compliance gaps, and platform resiliency soared. Real-time insights accelerated decisions across departments, and automated governance reduced both risk and cost.
The transformation's impact extended well beyond the institution. 'The solutions we developed weren't just about one bank,' Choppadandi reflects. 'We were creating blueprints that address industry-wide challenges—trust, transparency, compliance, and customer focus.'
Today, those architectural patterns are part of peer-reviewed publications and industry reference models, establishing Choppadandi as a thought leader in financial data innovation. His work didn't just change one bank's future—it helped define a new era for data-driven banking.

Thinking Differently about the Neural Intelligence: The Work of Swaminathan Sethuraman in Bridging Adaptive AI and Neural Network Innovation
A necessary mark in the field of artificial intelligence (AI) is the ability of the machines to constantly learn and adjust to changes in their environments. The key to this advancement is the field of continuous learning, which is a process that has attempted to endow machines with the human capacity of learning through a gradual process without losing former knowledge. The same paradigm has posed a technical challenge as well as a vision that propels the research of Swaminathan Sethuraman, a working data engineer and AI researcher. Having a long history in commercial data engineering and an ample history dealing with high-throughput data systems, Swaminathan has imbued his scientific work with a no-nonsense flair that is most prominent in his work in neural networks, continual learning and bio-inspired architectures. Hyperdimensional Computing as a foundation of Advancing Robust Learning His article on Brain Inspired Hyperdimensional Computing: The fast and robust neural networks (Journal of Applied Cognitive Science and Neural Architectures, Vol. 1, 2022) by Swaminathan positions him to present a special manner of developing robust neural networks. This paper has been inspired by the hyperdimensional computing framework that attempts to replicate the characteristics of human cognition and has formally proposed high dimensional binary vector spaces as a memory representation space capable of encoding, storing, and reconstructing memory representations efficiently in the AI models. The fact that Swaminathan had experience in stream processing, data integration, real-time analytics were very useful in the process of modeling these complex vector operations to scale. According to the article, Swaminathan said, we have to have AI systems that can reason and adapt simultaneously. Our built-in hyperdimensional spaces ensure that our system gives a sort of structure to not only persistence memory but also provides the fluid acquisition of knowledge. His work was the design of the memory-centric learning architecture, which substituted the dense layers with transformations of vectors in a space, secured against the data noise and gave better convergence of training. The extensive experience that Swaminathan has gained on distributed systems and large scale data streams by working on actual project that has been done using Spark, Kafka, and Scala based data lakes enabled the process of modeling bio inspired mechanism in a performant and scale manner. The paper was not only capable of showing an improvement in the synthetic benchmarks but also it established a computational framework which could drive tasks in lifelong learning, which has high demands of reliability under uncertainty. Lifelong Adaptation: A Future of Lifelong Learning Swaminathan added to this vision in 2021 with the book Continual Learning in Neural Networks: Overcoming Catastrophic Forgetting in AI Systems (American Journal of Autonomous Systems and Robotics Engineering, Vol. 1). He has been a co-developer in this work comprising of a framework of a solution to one of the most long-standing problems of AI, catastrophic forgetting. One thing about neural networks is that when presented with some new data, the networks will generally override earlier learned data hence leading to failure of the networks in practice. Some of the tactics examined in the paper were Elastic Weight Consolidation (EWC), replay buffers and dynamic network growth. Swaminathan got a practical experience of data volatility in his leadership in the design of real-time enrichment systems of payment platforms. His data engineering prowess played an essential role to represent processes, such as experience replay, to make memory-efficient mechanisms, which reuse minute subsets of prior experience to guard knowledge decays. Addressing the shortcomings of static architectures, Swaminathan produced the following words, 'Lifelong learning needs the ability to maintain stability and plasticity. Our method has the effect of bringing mathematical regularization into agreement to a degree with biological intuition.' His continuous task was to devise scalable constructions of replay plans and optimization procedures to safeguard elevated performance of tasks within sequential stream of learning. Its concepts had practical application on the fraud detection problem or personalised recommendation systems – things that he is also well vertically aware of due to his years of engineering production-grade pipelines. CS Graph Neural Networks In Graph Neural Networks in Complex System Modeling and Scientific Discovery (Transactions on Intelligent Machine Systems, Vol. 1, 2022), Swaminathan added to his research in discussing the capabilities of having graph neural networks (GNNs) as a powerful abstraction of an interaction-based system modelling. GNNs generalise neural networks to operate upon graph structured data so that dependencies can be discovered between entities, such as molecules in a scientific environment or transactional networks in a financial system. In this case, Swaminathan added value of his understanding of metadata-driven architecture and enormous amount of information linkages across various sources. In the actual commercial systems that he has spearheaded, application og tokenized data, encrypting layers, and device identities, the concepts of connectivity, node diffusion and temporal learning are steppingstones. Swaminathan indicated that graph models in this way permits us to imitate dynamic interdependencies of real-world systems. This is similar to the functionality of financial transaction, verification of identity, and detection of fraud in connected and dynamic networks. His occupation at the paper has been to model graph embeddings with GNNs in order to discover latent relationships, which is a skill he has developed by spending the last several years designing data lakes which connect 250K+ clients, ingesting more than 100 GB of data on a daily basis. Scaling Up Systems in biomedical Research The similarity between Swaminathan contributions in these publications is that the operationalisation of systems is achieved efficiently through academic systems. He has a track record of migrating rigid legacy systems onto open-source and of designing enrichment pipelines that can process terabytes of data per day, but always acts as a liaison between abstract theories and how that theory can be effectively implemented. In another example of Business Data Solutions application, he led a multi year conversion project to put open-source (Hadoop, Spark, Scala) stacks in place of licensed systems, creating a metadata driven low-code environment. The platform is currently supporting over 14000+ external endpoints per day and generates revenue directly to the enterprise. In a separate effort, B2B payment platforms token integration, Swaminathan designed and developed a pliable file ingestion protocol and encryption pipeline that allowed the clients to clearly define their own formats of payment. The systems employed the principles of encryption-in-motion, masking of tokens, and scalable batch templates and once again collaborated with his links of expertise in data security and modular design which resonated throughout his published research. About Swaminathan Swaminathan Sethuraman is a Lead Data Engineer and has more than 17 years of experience in designing and scaling up data systems to enterprise scale. He is presently managing the commercial data platforms that make over 30 million per annum. He is technicalized in Spark, Kafka, Scala, Hive and large-scale distributed processing and has deep knowledge in metadata-driven low code systems. Swaminathan is a multiple recipient of internal awards of excellence in engineering and has a postgraduate certification in Artificial Intelligence and Machine Learning in UT Austin. his work in the area of end-to-end learning, hyperdimensional computing, and graph neural networks indicates his dedication to the gap between theory at the bleeding edge and production systems.
