Encrypted Today, Decrypted Tomorrow: How PQC Saves the Day
As quantum computing advances, the encryption that protects our sensitive data today may be broken tomorrow. Post-Quantum Cryptography (PQC) offers a proactive solution, combining classical algorithms with quantum-resistant techniques to secure information against emerging threats.
In this session, we’ll explore hybrid encryption approaches that blend proven classical methods with next-generation PQC algorithms, ensuring data remains secure even in a post-quantum world. Attendees will gain a practical understanding of how encrypted data can be compromised via quantum attacks, and how hybrid strategies mitigate these risks.
Through real-world examples, we’ll examine scenarios such as stolen ciphertext, intercepted communications, and future-proof key management. You’ll learn when and how to adopt PQC in your systems, and how hybrid algorithms act as a bridge while standards evolve. This session balances technical depth with actionable guidance, providing both engineers and security leaders with insights they can apply immediately.
Whether you’re responsible for secure communications, cloud services, or sensitive user data, this talk will give you the knowledge to stay one step ahead of quantum-enabled threats. Walk away understanding why hybrid PQC is not just theoretical — it’s a necessity for protecting the digital assets of today against the computational powers of tomorrow.
Breaking the Monolith: The Art of Micro-Frontends
Large, monolithic frontends slow development, complicate deployments, and make scaling teams a headache. Micro-frontends bring modularity to the frontend, allowing teams to work independently, deploy features faster, and maintain large applications without chaos.
In this session, we’ll explore practical strategies for breaking a monolith into smaller, composable units while maintaining performance, UX consistency, and developer sanity. Attendees will learn real-world patterns, pitfalls to avoid, and actionable tips for adopting micro-frontends in modern web applications.
By the end of this talk, you’ll have a clear roadmap for making your frontend architecture more scalable, agile, and future-proof.
The Invisible Architecture of Innovation
Breakthrough technologies are often credited to brilliant ideas or cutting-edge tools, yet the greatest forces shaping innovation are usually invisible and rarely discussed.
They live in culture: the unspoken norms, incentives and assumptions that quietly guide how teams work, what risks they take, and which ideas are allowed to grow. Over the past decade, I have led engineering teams in start-ups, scale-ups and global enterprises, and I have seen how these hidden forces shape outcomes far more than technology alone.
This talk reveals how making the invisible visible can unlock creativity, build resilient cultures and drive meaningful progress.
Resilient by Design: Building Robust Architectures in High-Stakes Financial Systems
In high-stakes financial systems, resilience isn’t optional: it’s mission-critical. Failures can cost money, reputation, and customer trust, yet many teams struggle to build systems that are robust, maintainable, and agile at the same time.
This session explores practical strategies for designing resilient architectures in regulated and high-pressure environments. You’ll learn patterns such as fault-tolerant design, graceful degradation, redundancy, and risk-aware trade-offs, illustrated with anonymised examples from trading, payments, and high-frequency systems.
The talk focuses on principles and frameworks you can apply immediately, including ways to anticipate failure modes, mitigate risk, and make informed architectural trade-offs. You’ll gain actionable insights into how to design systems that keep running under pressure, without slowing delivery or overcomplicating architecture.
By the end of the session, attendees will understand how to build resilient, maintainable, and agile systems in regulated, high-stakes environments.

Clean JavaScript Code: An Oxymoron?
JavaScript has evolved from jQuery hacks to micro-frontends, React Native, and AI-assisted code, but the question remains: what does “clean” really mean today? In this talk, we’ll trace 20+ years of JS chaos, explore the evolution of clean code, and uncover the truths about maintainability, readability, and sanity in modern apps. Expect deep technical insights, brutal honesty, and a healthy dose of humor.
First Steps as a Team Lead: Rules and Mistakes
Stepping into a Team Lead role rarely feels like a promotion. Rather, it feels like entering a new dimension where responsibilities shift, influence changes shape, and the skills that once defined your value are no longer the ones you rely on most. Many new leads search for the "right" way to lead, only to discover that no universal playbook exists.
This talk explores that in-between space: the early uncertainties, the invisible expectations, and the quiet adjustments that define the first steps into leadership. We will examine why certain mistakes are so common, why some instincts fail while others become essential, and why this period feels both disorienting and clarifying at the same time.
Rather than offering a formula, this session asks a different question. How do you grow into leadership with intention, even when the path is unclear? You will leave with frameworks instead of checklists, perspective instead of prescriptions, and a clearer sense of how to lead imperfectly, authentically, and sustainably.
How to Build a House
Designing and constructing a home turns out to have far more in common with building complex software than most people expect. From shifting requirements and conflicting stakeholders to poorly scoped plans, technical debt in disguise, and the consequences of weak architecture, the experience is a masterclass in what not to do when delivering quality, as well as what to relentlessly protect.
In this talk, I’ll share the most valuable lessons learned from a challenging home-building project and translate them into practical takeaways for engineering teams: how to guard against misalignment, maintain craftsmanship under pressure, and design systems that stand the test of time. It’s a story about architecture, process, people — and why the smallest decisions can shape the entire structure, whether you’re building a house or a distributed system.
Bridging Strategy and Execution in Modern Technology Organisations
Effective software craftsmanship is more than writing code — it's about aligning strategy, innovation, and execution to create high-performing teams and scalable systems.
In this session, I will share insights from startups to Fortune 500 companies on sustainable engineering practices and agile processes. We will explore topics including scaling engineering teams while maintaining quality and culture, aligning software development with business strategy, balancing agile practices with long-term maintainability, mentoring future leaders, driving innovation in processes, and lessons learned from startups to enterprises.
Predict Before Breaking: The Simulation Crystal Ball
Imagine running your entire production environment in a fully synchronized digital twin — not just for testing, but for predictive reliability.
This talk explores creating digital twins of distributed systems, pipelines, and cloud infrastructure to simulate failures, test deployments, and optimize performance before impacting users. We will learn practical patterns for observability, automated simulation, and feedback loops that make “what-if” scenarios actionable in real time.
