You will get Scalable backend API or microservice in Golang
Project details
I will build a high-performance backend API or microservice using Golang.
If you need a fast and scalable backend, I can design and implement a clean solution that handles real production workloads. I focus on performance, reliability, and simplicity — no unnecessary complexity.
Whether it’s a REST API, microservice, or backend system, you will get a stable and maintainable implementation.
What you get:
• High-performance backend in Golang
• Clean API structure
• Scalable and reliable architecture
• Production-ready code
I have experience building backend systems and optimizing performance, so I understand how to design services that work efficiently under load.

React / Next.js Frontend Performance & Code Audit
Konstantin helped us audit our React (Next.js) frontend and provided valuable insights into performance and code structure.
He identified inefficiencies in rendering and state management that were affecting the user experience, and suggested practical solutions to improve performance and maintainability.
The feedback was clear, actionable, and easy to follow. Would definitely work with him again.

Laravel Application Architecture & Performance Audit
Konstantin did a great job reviewing our Laravel application. He quickly identified key performance bottlenecks and architectural issues we had been struggling with.
The audit was clear and actionable, with practical recommendations to improve performance and scalability. Communication was smooth, and his Laravel expertise is evident.
We’re planning to continue working with him on the next phase

Job Success
Tbilisi, Georgia - 7:25 am local time
I've spent most of my career as a long-term technical partner for businesses, not jumping between short gigs — which means I know what it takes to build systems that scale and survive real-world conditions.
What I build:
- Laravel backends and SaaS platforms (multi-tenant, queue-heavy, high-load)
- REST & WebSocket APIs built for performance and maintainability
- Golang microservices for performance-critical components
- AI integrations (LLM APIs, automated workflows, intelligent features)
- Third-party & payment gateway integrations
- Docker-based infrastructure and CI/CD pipelines
Stack:
Laravel · PHP · Golang · Vue · React · MySQL · PostgreSQL · Redis · Docker · Kafka
I work best with:
- Products that need solid architecture from the start
- Teams that need a senior engineer who can lead and deliver independently
- Existing systems that need rescue, optimization, or scaling
