You will get a Java Backend Developer for a custom design builder platform
Top Rated
Project details
This project stands out due to its focus on custom backend development for a house design builder solution, tailored to the specific needs of the client. By leveraging Java, Spring Framework, MySQL, REST API, and Python for ML-powered components along with advanced business logic, I created a flexible and scalable system that enables users to design personalised floor plans with ease. My experience leading the backend team and delivering high-quality, secure solutions ensures that the system is both reliable and optimised for growth. The integration of cutting-edge technologies and a client-centric approach sets this project apart from standard development solutions.

Lviv, Ukraine - 10:12 pm local time
On the backend, my core stack is Java, Spring Boot, and Spring Framework, with REST APIs, Hibernate/JPA, PostgreSQL, MySQL, MongoDB, and SQL for persistence. For infrastructure I work across AWS, GCP, and Azure, and I'm comfortable with Docker for containerisation and environment consistency, Kubernetes, and CI/CD pipelines. When a project needs it, I also write Python, Node.js, and front-end code in React or Angular, including JavaScript for client-side logic. I have working experience with PHP for web backend tasks, and I've applied Python beyond scripting, including data processing pipelines and ML-adjacent work such as model integration and feature engineering.
The impact side: over 5 years I've designed 120+ REST APIs, built 10+ microservice architectures from the ground up, and worked on systems serving anywhere from 10K to 500K+ users depending on the project scale. Performance work is something I take seriously: on several engagements I've cut API response times by up to 60% and improved overall system performance by 40%+ through targeted refactoring and architectural improvements, rather than costly rewrites.
I've also worked extensively with enterprise-level database schemas, writing and optimising complex SQL queries, indexing strategies, and data models across tables with 100K+ records. The production systems I've maintained have consistently held 99.9% uptime, which at that scale doesn't happen by accident. It comes from solid monitoring, thoughtful deployment practices, and knowing where the failure points are before they become incidents.
My clients get clear communication, fast responses, and code that's actually maintainable six months later. I'm business-focused; I care whether the thing solves your problem, not just whether it compiles. As one client put it: "he doesn't just write code; he thinks about why we need it in the first place."
Not only a Java developer, I've led teams, mentored junior devs, and run cross-functional projects where the technical and the human side both needed managing. Clean code matters. So does knowing when to push back, when to unblock someone, and when to just make the call.
I am always open to long-term collaborations and challenging software engineering projects involving Java, Spring Boot, React, Angular, cloud systems, microservices architecture, and modern backend engineering.
Need a Java developer who ships clean code and tells you when you're building the wrong thing? That's the conversation worth having. Drop me a message.
Steps for completing your project
After purchasing the project, send requirements so Ihor can start the project.
Delivery time starts when Ihor receives requirements from you.
Ihor works on your project following the steps below.
Revisions may occur after the delivery date.
Initial Consultation & Planning
During this step, I will gather all the necessary information, including user stories, design preferences, and integrations. This will help me define the architecture and scope of the project before development begins.
Backend Development & Integration
I’ll design the backend architecture and implement features like user management, floor plan creation, and data storage. I'll also ensure everything integrates seamlessly with any external services.
