About

The engineer behind the systems

Backend-focused full stack engineer working on live financial products.

I am a Senior Software Engineer with 3+ years of experience building production web and financial technology platforms. My core strength is backend engineering in Node.js and Express.js, with full-stack delivery using React.js, Next.js and TypeScript.

Alongside application development I have practical DevOps and cloud experience, deploying and maintaining containerized applications on Google Cloud Platform with Docker and Kubernetes.

Day to day I work on invoice financing, real-time payments, settlement workflows, banking integrations and blockchain integration inside live financial products — which means I own both the engineering and the financial business logic behind it.

Backend Engineering

REST APIs, business logic, authentication & security, event handling and transaction schedulers.

Full Stack Delivery

React.js, Next.js and TypeScript features shipped alongside the services that power them.

Fintech & Payments

Invoice financing, Murabaha models, real-time payments and settlement workflows.

DevOps & Cloud

GCP, GKE/Kubernetes, Docker and Linux VMs with secure secret and key management.

Blockchain / Web3
