What I'm looking for

I’m looking to build and scale secure FinTech products—owning Rails backend architecture, real-time ActionCable features, and reliable payment/ERP integrations with strong engineering practices.

I’m a Ruby on Rails developer with 5+ years of hands-on experience designing, developing, and deploying production FinTech systems. I specialise in distributed system architecture, microservices-style integrations, and building real-time features with ActionCable (WebSockets).

I deliver reliable, secure integrations end-to-end—integrating five payment and banking APIs with HMAC-SHA256 webhook verification, idempotent request handling, and IP whitelisting. I’ve maintained scalable RESTful APIs across UI, API, and database layers, with a track record of delivering FinTech products with zero security incidents across 5+ payment integrations.

I’m also focused on performance and operational resilience: I diagnose and resolve database bottlenecks using recursive CTEs, query optimisation, and N+1 elimination. From architecting a production 3-tier Rails↔Tally ERP bridge with idempotency controls and dual-layer timeout failover to ensuring reliable Sidekiq/Redis background processing, I aim for systems that stay correct under failure and scale with confidence.
