You will get a Java Spring Boot REST API Development for IoT or Automotive Backend
Project details
Looking for a Java Developer or Spring Boot Developer to build a production-grade Java Spring Boot REST API for your automotive, IoT, or enterprise Java backend?
As a Java Developer and Spring Boot Developer, I build Java REST APIs that handle real-world load — with production experience delivering Spring Boot REST APIs for automotive OEM integrations with BMW, Mercedes, Ford, Volvo, and Stellantis.
As a Spring Boot Developer, every Java REST API delivery includes: Spring Boot REST API with OpenAPI docs, Spring Security OAuth2 and JWT, Spring Data JPA with PostgreSQL and Liquibase, Redis caching, Apache Kafka integration, Docker and Kubernetes, JUnit 5 and Mockito with SonarQube quality gate. As a Java Developer and Backend Developer, I own the full Spring Boot lifecycle — not just the happy path.
As a Java Developer with IoT and automotive experience, I have built Spring Boot microservices for vehicle lifecycle management, OEM API integrations, and Kafka telemetry streaming at enterprise scale.

About Yurii
Software Architect | Java | Spring Boot | Apache Kafka | AI Consultant
Kyiv, Ukraine - 10:20 pm local time
in software architecture review for Java and Spring Boot backends — and AI consultant
work for companies building AI on top of Java and Spring Boot infrastructure.
As a Software Architect and AI Consultant, I work with Java and Spring Boot engineering
teams where something is clearly wrong: the software architecture is slowing delivery,
Spring Boot services degrade under Apache Kafka load, and AI consultant integration is
stuck before it starts. My job as a Software Architect and AI Consultant is to review
your Java and Spring Boot architecture, find the root cause, and tell you what to fix first.
I don't write production code for clients. As a Software Architect working at the
consulting level, my work is software architecture review, diagnosis, and planning.
Your Java and Spring Boot team implements the fixes. After working with me as a
Software Architect and AI Consultant, your team is stronger — not dependent on an
external contractor.
━━━ WHAT I DO ━━━
→ Software Architecture Review — "Why Can't We Ship?"
Core Software Architect service. A software architecture review of your Java and
Spring Boot system: where velocity is lost, what
is causing it, what to fix first. As a Software Architect, I focus on Java and
Spring Boot root causes, not symptoms. Every software architecture review includes
a written report with specific priorities — not generic "pay off tech debt."
Scope: 1–3 Java / Spring Boot services. Delivery: 5–7 days.
→ Apache Kafka Audit — "Why Is Our Data Unreliable?"
Most Java and Spring Boot teams running Apache Kafka have never had a proper software
architecture review of their Apache Kafka pipeline. As a Software Architect with
production Apache Kafka experience — 100M+ events/day — I audit your Apache Kafka
setup: topics, consumer groups, Apache Kafka error handling, Apache Kafka DLQ,
Apache Kafka consumer lag. As a Software Architect and Apache Kafka specialist, I've
seen every Apache Kafka failure pattern in production Java and Spring Boot systems.
The Apache Kafka audit findings directly inform AI Consultant work — most Apache Kafka
issues I find also block AI Consultant integration.
Delivery: 3–5 days.
→ AI Consultant Assessment — "Are We Ready for AI?"
AI consultant work starts with your Java and Spring Boot backend — not with the model.
As an AI Consultant and Software Architect for Java and Spring Boot systems, I check
whether your software architecture can support AI integration: data pipeline, API
design, Apache Kafka event streaming, Java data quality. I deliver an AI Consultant
report with specific gaps and a clear roadmap. Most Java and Spring Boot software
architectures fail the AI Consultant readiness check before a single model is
deployed.
Delivery: 5–7 days.
→ Full Software Architecture Diagnostic
A complete software architecture review of your Java and Spring Boot platform. Two
weeks, interviews with your Java and Spring Boot engineers, full picture: velocity
blockers, AI Consultant gaps, Apache Kafka issues, architecture debt. As a Software
Architect and AI Consultant delivering a full diagnostic, I give you a prioritized
6-month action plan with effort and business impact for each Java and Spring Boot item.
━━━ WHY THIS SOFTWARE ARCHITECT ━━━
As a Software Architect and AI Consultant, I've built and owned Java and Spring Boot
microservices processing 100M+ vehicle telemetry events per day at a major European
company. That's production Apache Kafka at scale — Apache
Kafka consumer lag, Apache Kafka DLQ failures, Java and Spring Boot performance under
real load. I know what a Java and Spring Boot software architecture looks like when it
can't handle pressure — because I've been inside it as a Software Architect. That's
what makes every software architecture review I do different from a checklist.
Before software architecture consulting, I spent 7 years as a design engineer at
Antonov Aerospace — an industry where software architecture review is not optional
and failure has real consequences. That background shapes how I work as a Software
Architect and AI Consultant. My standard for Java and Spring Boot reliability is different.
Public mentor at Sigma Software University — teaching Java and Spring Boot
engineering practices to the next generation of Software Architects.
━━━ TECH ━━━
Java 17+, Spring Boot, Spring WebFlux, Apache Kafka, PostgreSQL,
Redis, Kubernetes, Docker, AWS, Prometheus / Grafana, gRPC.
━━━ WHO I WORK WITH ━━━
As a Software Architect and AI Consultant, I work best with Engineering Managers who
know their Java and Spring Boot software architecture has a problem but need an outside
perspective — and CTOs at companies where the Java and Spring Boot platform is 3–8
years old and blocking both velocity and AI consultant integration.
Send me a short description of your Java and Spring Boot architecture and what is not
working. I'll respond within 24 hours.
