Project details

Are you looking for a robust, production-grade backend architecture? I specialize in engineering secure, fault-tolerant web applications and distributed microservices.

With hands-on experience building systems capable of handling thousands of concurrent users with zero failures, and developing strict APIs for fintech data pipelines, I deliver absolute reliability.

What you will get:

Custom REST APIs: Scalable endpoints built with Java 21 and Spring Boot 3.

Hardened Security: Stateless JWT authentication, HMAC-SHA256 request signing, and atomic rate-limiting.

Advanced Integrations: Event-driven communication via Apache Kafka, Redis caching, or customized AI workflows using Spring AI.

Production-Ready Delivery: Docker containerization with optional Prometheus and Grafana observability.

Whether you need a foundational CRUD API or a scalable microservices backbone featuring SAGA choreography, I write clean, highly concurrent code. Let's architect a solid foundation for your application.

About Shrey

Shrey D.Status: Offline
Backend Dev
Anupshahr, India - 12:10 am local time
Backend Software Engineer specializing in designing and shipping production-grade, event-driven microservices. Currently working as a Backend Engineering Intern at a US-based fintech, managing HMAC request signing, robust REST API design, and Apache Airflow ETL pipelines.

I focus on building fault-tolerant architectures that scale. My technical stack and core capabilities include:

Core Backend: Java 21, Spring Boot 3, REST APIs, and Spring Cloud.

Distributed Systems: Microservices architecture, Apache Kafka event backbones, Redis caching, and SAGA choreography.

Security & Observability: Stateless JWT authentication, HMAC-SHA256 request signing, Docker containerization, Prometheus, and Grafana.

AI Integrations: Developing end-to-end AI agent workflows using Spring AI and function-calling.

I write clean, highly concurrent code tested for absolute reliability—including architecting multi-service platforms capable of sustaining high-volume concurrent traffic with zero failures.

Let's engineer a scalable, secure foundation for your application.

Steps for completing your project

After purchasing the project, send requirements so Shrey can start the project.

Delivery time starts when Shrey receives requirements from you.

Shrey works on your project following the steps below.

Revisions may occur after the delivery date.

Requirement Analysis & Architecture Design

We will review your specific needs, define the API endpoints, and design the database schema and system architecture before coding begins.

Core Backend & Database Setup

I will initialize the Spring Boot environment, configure the database connections, and build the core data entities and models.
