WORK HISTORY
Senior Software Engineer @Ophelos, Part Of Intrum
London, GB
Act as technical architect and second-in-command for a greenfield, AI-first re-architecture of Ophelos’ debt resolution platform, delivered in 8 weeks by a cross-functional team spanning engineering, data, UX, product, and leadership. Own system architecture, data models, service boundaries, and language choices for core platform systems.Designed and delivered a full communication operating system, templating & campaign engine, and state-driven case lifecycle platform from scratch. Reframed business logic as a state-based system rather than binary open/closed cases, reducing regulatory risk, over-communication, and operational cost. Designed a financially auditable ledger as the backbone of the platform. Introduced Spec-Driven Development to align humans and AI-assisted coding around shared intent and constraints. Designed AI-assisted workflows constrained by deterministic decision engines for safety, predictability, and cost control. Chose database-level Row Level Security (RLS) over application-only authorization to eliminate classes of data-leak risk and ensure consistent access control. Act as primary architectural alignment point for UX, Data, and Executive stakeholders, including CTO-level validation. Provide ongoing architectural support during phased rollout across multiple European markets, ensuring regulatory correctness and system stability.

ABOUT KYLE WELSBY
Hey there! I’m Kyle — a Senior Software Engineer working on regulated fintech platforms, large-scale system architecture, and long-lived technical decisions at Ophelos / Intrum.I specialise in fintech systems and platform architecture, where correctness, regulatory safety, and sustainable operating cost matter as much as delivery speed. My strongest work involves owning system boundaries, data models, and architectural trade-offs where success metrics emerge over time rather than immediately after launch.Recent highlights: Acted as technical architect and second-in-command for a greenfield, AI-first re-architecture of Ophelos’ debt resolution platform, delivered in 8 weeks by a cross-functional team. Designed core platform foundations including communication systems, templating engines, state-driven case lifecycle, and an auditable financial ledger. Introduced Spec-Driven Development to align humans and AI-assisted coding around shared intent and constraints. Designed AI-assisted workflows constrained by deterministic decision engines for safety, predictability, and cost control. Known internally for calm judgment under ambiguity and for pushing back when correctness or regulatory clarity is at risk.I bring: System-level ownership — I take responsibility for architecture, data, and long-term outcomes, not just features.🤝 Alignment without authority — I work best in flat hierarchies, creating clarity across engineering, data, UX, and leadership. Pragmatic AI adoption — I use AI where it adds leverage, and constrain it where determinism is required. Positive energy — engineering is a team sport, and I aim to make the game better for everyone involved.I’m most excited by fintech, tech-for-good, climatetech, mental health tech, regulated systems, and problems where getting it right matters deeply to real people. Let’s build durable systems that earn trust #AI #Ownership #Growth #GSD
