Olayiwola Akinnagbe is a Senior Backend Engineer and AI researcher working at the intersection of financial technology, distributed systems, and intelligent human–AI collaboration. His work is guided by a clear conviction: systems should not merely function. They should scale, adapt, and strengthen the people who use them.

In the fintech sector, Olayiwola architects API-first, event-driven microservices that power payments, loan origination, and high-volume transaction platforms processing over one million API requests daily. He designs secure and resilient backend infrastructures using Java, Spring Boot, Kafka, and AWS. By applying CQRS principles, low-latency search optimization, and cloud-native deployment strategies, he consistently delivers measurable improvements in latency, throughput, and system reliability.

His contribution extends beyond engineering practice into scholarly research. He is the author of the peer-reviewed paper “Human–AI Collaboration: Enhancing Productivity and Decision-Making,” where he reframed artificial intelligence not as automation, but as cognitive partnership. His work examines how humans and intelligent systems can intentionally distribute cognitive responsibility while preserving human agency. This framework has been recognized for its clarity in explaining productivity acceleration and hybrid decision-making models.

Olayiwola holds a Master’s degree in Information Technology, graduating in the top five percent of his class, with research focused on machine learning–based malware detection. His broader publications span AI in finance, cybersecurity, federated learning, and predictive modeling for risk management. This combination of production engineering and academic inquiry enables him to translate theoretical insight into secure, deployable, and economically sound systems.

An AWS Certified Solutions Architect and Developer, he is committed to building architectures that are secure by design, resilient under pressure, and optimized for real-world constraints. He mentors engineers, contributes to technical scholarship, and speaks on system design, fintech infrastructure, and the evolving discipline of human–AI collaborative intelligence.

For Olayiwola, technology is not only about writing code. It is about designing systems that expand human capability while preserving judgment, responsibility, and trust.

Jacqueline “Jaki” Stockwell is the CEO & Founder of Leadership Through Data, a global company who provide information management training and consultancy to both public and private sectors.

Alongside running the business, Jaki is also a professional speaker and is invited to attend international conferences and events. Jaki’s sessions are all about teaching information managers how to deliver fun, engaging and informative presentations to their colleagues in their respective businesses. As information managers know, it’s important that everyone in a business understands what information management is, however getting them to listen and comply is undeniably difficult. Jaki’s teaching methods empower information managers to think differently and use psychology along with a combination of styles to get their message across; after all, one size doesn’t fit all.

As well as being an international speaker, Jaki’s creative and inspirational leadership style and proactive approach to information management has led her to mentor others. She is quoted by clients and industry peers who say that “her positive attitude is infectious” and “she is totally human in her approach”.

Jacqueline’s aim in her career is to simplify information management what is unfortunately viewed as a complex and uninteresting topic, into relevant practical and enjoyable solutions which can be understood and implemented by all. The safety and security of information is both key to successful businesses but also a threat to their success if not managed effectively.

Whether in business or in her personal life, Jaki is always mindful of her sustainability efforts. At home she loves to upcycle and breathe new life into preloved furniture and décor. She loves to craft and sew and enjoys gardening and growing fruit and vegetables - no matter how successful the harvest may be .

Sankalp Gilda is a Staff ML Engineer and independent researcher focused on epistemic accountability and structured reasoning for AI-assisted workflows in regulated and high-stakes domains. He holds a PhD in Astronomy and has six-plus years of production data science experience spanning time-series analysis, uncertainty quantification, and MLOps -- most recently driving AI for electric-vehicle systems in greentech as well as in oil and gas.

He created tsbootstrap, an open-source Python library for bootstrapped time-series resampling (87+ stars, sktime-integrated), and gave its tutorial at SciPy 2024. His other public OSS spans the security and developer-safety ecosystem -- idna-ip-literal-smuggle-rules, a CodeQL/Semgrep ruleset and gopatch auto-fix codemod for a Go IDNA-canonicalization bug class (UTS-46 digit-fold IP-literal smuggling) he privately disclosed to the Go team in April 2026, and mcp-keyring-injector for session-scoped credential safety in MCP environments. Recent research includes workshop papers at ICLR 2026 -- Logical Reasoning of LLMs (algebraic invariants for LLM reasoning chains and weakest-link reliability propagation) and AI in Finance (epistemic accountability and generator-ratifier disjointness for agentic financial AI). He builds Verity, a reasoning-layer system for AI coding assistants in regulated environments, currently in private development.

Outside work he's drawn to high-commitment activities -- skydiving, scuba diving, kitesurfing -- that reward the same combination of careful preparation and decisive action that good engineering does. He consults across industries through DeepThought Solutions on AI governance, structured reasoning, and ML-for-regulated-domains problems.
