What I'm looking for

I’m looking for a team where I can take ownership, ship fast, and build secure, scalable systems end-to-end. I want to work on fintech-grade products, collaborate in distributed teams, and grow through modern cloud and CI/CD practices.

I’m a Full-Stack Developer with 4+ years’ experience building secure, scalable fintech and high-trust applications for global clients. I design, develop, and deploy production-ready systems end-to-end—working confidently across frontend, backend, database, and cloud.

At GriffinGlobalTechnologies (April 2024–Present), I develop and maintain backend services using NodeJS (ExpressJS and NestJS) and C#. I integrate third-party APIs for communication, payments, and reporting, and build event-driven micro-services for async processing while keeping reliability and scalability front and center.

I also focus heavily on quality and delivery: I write unit and integration tests using Jest, XUnit, and Test Containers; Dockerize services for local and production runs; and set up CI/CD pipelines on GitHub Actions. My cloud work includes AWS resources such as EC2, ECS, S3, Lambda, DynamoDB, CloudWatch, and related serverless components.

Previously at Teach2Give (Oct 2023–April 2024), I led product team sprint planning, broke requirements into tasks, and delivered backend APIs for payments and reporting. Earlier at Rieti (Sep 2022–Oct 2023), I supported roadmap planning with the business team, created UI mockups in Figma, implemented interfaces with AngularJS, and iterated based on user feedback—always with ownership, fast shipping, and strong collaboration.
