Individual contributor on backend systems for business current accounts, payments, migrations, and integration platforms at Allica Bank, in a regulated fintech environment. • Designed an internal Claude Code AI tool, a "second‑brain" knowledge system for capturing and retrieving engineering context via LLM‑maintained wiki articles, with guardrails against PII/credential capture. • Built and shipped an AI agent skill automating FCA REP20 regulatory reporting from Azure logs, replacing a manual quarterly task with a reusable tool. • Integrated payroll's payment processing with Allica's AI‑powered bulk‑payment file system, and decoupled its AI components from non‑AI consumers via a feature‑flag redesign. • Led payroll system integrations as sole IC engineer, partnering with Product, Design, and Compliance to define and deliver a scalable architecture. • Delivered the audit‑logging framework (taxonomy, sanitiser, async writer) for regulatory compliance and extensibility. • Owned the account‑switching product end‑to‑end from beta to live, enabling ~20% month‑on‑month growth in business migrations. • Designed payee validation for single and bulk payments, adding compliance‑driven fraud checks that reduced errors and strengthened regulatory controls. • Led a greenfield Kotlin/SpringBoot migration from Azure Event Grid to Service Bus, adding DLQ/retry patterns for reliable, scalable event‑driven workflows. • Built internal Ops/Admin tooling that cut manual effort and improved incident triage, auditability, and observability. • Automated customer/ops communications for account switching, cutting mail‑server load by 65% while improving transparency for Operations and Compliance. • Stabilised and optimised Xero/Sage accounting integrations, improving sync reliability and driving a 68% YoY increase in adoption. • Drove architecture reviews, on‑call, incident response and post‑incident improvements, while mentoring new engineers.

Developed backend services for Reliability Modeler application, translating complex client requirements into scalable solutions. Designed and implemented in‑memory caching, reducing database calls and improving feature performance by up to 80%. Refactored data import pipelines to support 1M+ records, removing earlier system bottlenecks. Built Import History functionality using CQRS and Outbox pattern with Kafka, Debezium, and Zookeeper. Built Import History from scratch using CQRS and Outbox patterns with Apache Kafka, Debezium and Zookeeper, keeping the import and history modules consistent. Built gRPC service-to-service calls with request and response contracts defined in Protobuf, keeping internal call latency low. Integrated the Hitachi APM platform through RabbitMQ ingestion and aggregation services, and refactored the codebase to bring response times back within service level agreement (SLA) targets.

About

Senior Backend Engineer with over 6 years of experience building and running event-driven, cloud-native systems in regulated fintech environments.At Allica Bank, I work on backend services that power business current account onboarding, migrations, and payment workflows. Alongside core backend engineering, I actively experiment with GenAI and agentic development for rapid prototyping and internal POCs. This includes using LLM-assisted workflows to explore automation, developer productivity improvements, and fast validation of new product ideas—while staying mindful of security and compliance constraints in fintech. Alongside core backend engineering, I design and build internal GenAI/agentic tooling. I built an AI agent skill that automates FCA REP20 regulatory uptime/downtime reporting from infrastructure logs, replacing a manual quarterly process now in production use. I also designed a Claude Code-based "second-brain" knowledge system with built-in data-handling guardrails (PII/credential scanning) for capturing and retrieving engineering context, currently in use ahead of a security-reviewed org rollout. I've also integrated production payment pipelines with an internal AI-powered bulk-payment processing system, including cross-team architecture work to decouple AI-specific components for non-AI consumers.I regularly contribute to architectural design, code reviews, production support, and mentoring—owning systems end to end with a strong emphasis on reliability, observability, and clean system design.Previously, I’ve also worked in the energy domain, where I applied backend engineering principles to automate and optimize large-scale operational systems.I’m interested in senior backend roles within fintech or payments teams where ownership, system quality, and real-world scale matter.
