Full Stack Developer
About this Gig
Need a reliable Senior Engineer to build enterprise-grade, scalable REST APIs?
With 4+ years of experience, I specialize in high-performance Java Spring Boot applications and AWS serverless deployments. I prioritize clean architecture, optimal database queries, and seamless infrastructure over basic coding.
What I Can Do For You:
- Custom REST APIs: Secure, scalable, and well-documented Java/Spring Boot endpoints.
- Performance Tuning: Optimizing sluggish APIs, complex search queries, and heavy POST implementations using async processing.
- Database Integration: Efficient data modeling with PostgreSQL, MongoDB, and Neo4j.
- AWS Infrastructure: Java-based AWS CDK deployments via API Gateway, Lambda, and EventBridge.
- Third-Party Integrations: Secure connections to external services and payment gateways.
Why Choose Me?
- Senior-level enterprise experience.
- Maintainable code that doesn't require a rewrite in six months.
- Clear, daily communication.
Please message me before placing an order to discuss your requirements and ensure a perfectly scoped plan!

FAQ
Can you work on an existing Spring Boot codebase, or do you only build from scratch?
I am highly experienced in jumping into existing enterprise codebases. Whether you need to add a new microservice, integrate a new database, or refactor legacy code for better performance, I can seamlessly integrate with your current setup.
My current API is very slow, especially for search. Can you fix it without rewriting everything?
Absolutely. I specialize in surgical optimizations. For example, I can optimize heavy POST endpoints using asynchronous processing (like DeferredResult) to drastically improve search response times, all without forcing you to change your existing API contracts or response types.
Do you handle the cloud deployment, or do you just provide the code?
I handle the infrastructure as well! I provide Infrastructure as Code (IaC) using a Java-based AWS CDK application. This means I can cleanly provision your AWS resources—like API Gateway, Lambda, and EventBridge—ensuring your app is deployed scalably and securely.
What is your working style and availability?
I treat these projects as specialized technical consulting. I take on tightly scoped milestones to ensure high-quality delivery. You can expect clear, daily communication regarding project updates and milestones.
What information do you need from me before we start an order?
To ensure we hit the ground running, please message me with a brief overview of your business logic, any existing codebase/repository access, your database schema, and expected JSON request/response formats.
Do you offer custom packages if my project doesn't fit the standard tiers?
Yes, absolutely. Every backend system is unique. Please send me a message with your requirements, and I will create a custom, perfectly scoped offer tailored specifically to your project's needs.
