From shipping features to owning whether they stay up.

I sit in the Trade Finance team, building a new trade finance module for BankUltimus - the core banking platform Leads ships to financial institutions. The work spans a Spring Boot backend, an Angular 19 frontend, and the event-driven plumbing underneath both. It is the first place I have worked where a defect is not a degraded experience but a misdirected payment with a customer attached.

• Built SwiftFusion, a trade finance application implementing the SWIFT ISO 20022 messaging standard on Spring Boot and Angular 19 - now running in the NRBC Bank and Southeast Bank environments.
• Moved inter-service messaging onto Apache Kafka for event-driven flows and gRPC for synchronous service-to-service calls, containerised with Docker so an environment is reproducible rather than remembered.
• Contributed to a distributed transaction orchestrator written in Rust on Actix Web, implementing Two-Phase Commit, choreographed Saga, and hybrid coordination models for bank-grade transactional workflows.
• Instrumented services with Prometheus, Grafana and Elasticsearch - metrics, structured logging, dashboards and alerting that fires before a customer notices rather than after.
• Maintain and extend the Notification & Alert System on .NET Core with background workers, owning its deployments, reliability work and feature additions.

Ran delivery across a large book of client products - fintech, marketplaces, media and internal tooling. Agency work means volume: many systems, short runways, and no opportunity to rebuild something because it turned out inconvenient. The job was half architecture and half making a team predictable.

• Led frontend and backend teams building scalable systems across concurrent client products, owning architecture decisions end to end.
• Set up CI/CD pipelines so releases stopped being events and became routine.
• Ran deployments on DigitalOcean and GoDaddy, including DNS, TLS and reverse-proxy configuration behind Nginx.
• Managed and mentored junior developers through code review - the measure is fewer repeated mistakes, not faster merges.
• Worked directly with UX and UI designers so API shapes and interface needs stopped drifting apart mid-build.

Moved from writing features to owning whether they stayed up. This is where deployment stopped being someone else's job.

• Deployed frontend and backend components to DigitalOcean droplets with Nginx as reverse proxy.
• Integrated APIs on the client with RTK Query, cutting redundant round trips through cache-aware data fetching.
• Held direct client communication to keep scope and delivery aligned, which is its own engineering skill.

First exposure to systems with real users attached. Built the real-time layer that then showed up in nearly every product I touched afterwards.

• Built and deployed Express.js backends.
• Implemented real-time messaging and notification systems with Socket.IO, including the reconnection and delivery edge cases that only appear on unreliable mobile networks.
