About Ismail

Ismail K.Status: Offline
Java and Spring Boot Expert | Ready to deliver your Secure Payment API
5.0  (1 review)
Bochum, Germany - 2:56 pm local time
I’m a senior Java / Spring‑Boot engineer with 10 + years of experience building high‑traffic, PCI‑DSS‑compliant payment systems and micro‑service architectures for SaaS and fintech companies.

Why I’m a great fit
- Designed and shipped a Stripe‑Connect micro‑service that processes > 2 M transactions/month with latency under 150 ms.
- Write clean, test‑driven code; every project has 100 % unit and integration coverage using JUnit 5 and Testcontainers.
- Deployments are containerized, automated with Docker and GitHub Actions, and run on AWS (ECS/EKS) using Terraform for infrastructure‑as‑code.
- I can deliver a functional prototype within 48 hours and iterate quickly based on feedback.

My usual approach
1. Review the existing API specification and data model.
2. Build a Spring Boot starter with the required Stripe or Wise integration and JWT security.
3. Add comprehensive automated tests and configure a CI/CD pipeline.
4. Deploy to a staging environment, run load tests, and hand over full documentation.

Deliverables
- Complete source code in a private Git repository.
- OpenAPI/Swagger specification.
- Docker image ready for production.
- CI/CD configuration (GitHub Actions).
- Two hours of post‑delivery support.

I’m happy to begin with a small paid milestone to build confidence.

Next steps – Let’s schedule a brief 15‑minute call to discuss your requirements and lock in the timeline. I look forward to helping you launch a secure, scalable payment solution.
