About Mehuol

Mehuol D.Status: Offline
Senior Java Full Stack Developer | Spring Boot & Microservices Expert
Karachi, Pakistan - 8:51 am local time
I'm a Senior Java Full Stack Developer with 6+ years of experience building high-performance, scalable backend systems for fintech, digital signature, and enterprise platforms used by millions of users across Europe and Asia.

I specialize in Java (8–21), Spring Boot, and Microservices architecture, with hands-on expertise in event-driven systems using Apache Kafka, cloud-native deployments (Docker, Kubernetes, AWS), and modern design patterns like Hexagonal Architecture and Domain-Driven Design (DDD).

Here's what I bring to your project:

▪️Backend Development: Spring Boot, Spring Cloud, Spring Security, Hibernate/JPA, RESTful & GraphQL APIs
▪️Microservices & Event-Driven Systems: Apache Kafka, RabbitMQ, CQRS, Saga Pattern
▪️Databases: PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch
▪️Cloud & DevOps: AWS (EC2, S3, RDS, Lambda), Docker, Kubernetes, CI/CD (Jenkins, GitLab)
▪️Frontend: Angular, React (for full-stack projects)
▪️Security: OAuth 2.0, Keycloak, mTLS

Recent highlights:

▪️Built a core document-conversion service for a GoSign e-signature platform serving millions of users across Europe.
▪️Engineered B2B payment systems processing $50M+ in monthly transaction volume at 10,000+ TPS.
▪️Reduced API response times by 30% and cut application startup time by 60% through caching and GraalVM optimization.

I care about writing clean, testable, production-ready code and communicating clearly throughout a project, from requirements to deployment. Whether you need a scalable backend built from scratch, a legacy system modernized, or an existing team strengthened, I'm ready to help.

Let's talk about your project.
