Project details

Fast-tracking your product launch requires a reliable backend and a responsive frontend built for speed and future scalability. Having shipped 20+ products over 7+ years, I help you establish a solid foundation that gets your startup to market quickly.
We will build core REST APIs, clean database structures, and dynamic React components. Whether you need to streamline user workflows or connect third-party services, we will handle the technical execution from end to end. You get a robust launchpad designed to handle early user traction smoothly.
I help founders bring ideas to life with clean code structures and efficient development loops.

I solve technical bottlenecks in:
 • Core backend REST API design and implementation
 • Database schema modeling and rapid data structuring
 • React and Next.js frontend setup and routing
 • Tokenized user flows and secure session management
 • Third-party service integration and webhook configuration
 • Deployment pipeline preparation for early-stage apps

Product Listing Website (MVP) - Developer needed We were happy to win Andrii for this job. We awarded this job to him because he communicated a technical solution and timeframe that convinced us. During the project we got daily reports so it was easy to follow the status. He delivered milestones in time. Very responsive with good English. We can highly recommend to work with Andrii.

Building a SaaS or MVP and need a backend that won't fall apart as you scale?

I’m a senior Full Stack Laravel Developer with over 7 years of commercial experience, 9,000+ total hours logged, and 20+ shipped products. My primary stack is built around robust Laravel backends and sleek React front-ends, ensuring secure, high-performance web applications that hold up under real-world usage.

As a Full Stack Laravel Developer, I take ownership of systems end-to-end. I’ve built 3 scalable SaaS platforms on Laravel, PHP, React, and Node that automated complex multi-provider payment routing and transaction flows. Whether it's developing 4 custom Product Listing Websites from scratch with 99.9% uptime or delivering 5 critical addons for existing websites with zero downtime, I focus on clean architecture that lasts.

As a Front-end React developer, my work centers on Next.js and React interfaces, focusing on tokenized flows, lightning-fast rendering, and consistent UI logic under heavy traffic. I tie these smooth frontend flows directly to deep Laravel backend processing, handling MongoDB and SQL database migrations that reduced response times by 40%.

In my day-to-day work as a backend engineer, I design systems that power high-load services. I regularly work with Laravel to build clean modular architectures, Supabase real-time sync, and optimized databases. By applying strict KISS, DRY & SOLID principles alongside supplementary Node.js experience, I’ve achieved 35% faster development cycles, shipping production-ready code smoothly.

When projects require AI functionality, I bring hands-on experience integrating it directly into backend systems. As a dedicated AI developer and LangChain developer, I implement custom AI agent workflows and production-ready RAG pipelines using OpenAI API and Anthropic Claude across 10+ AI-Powered Automation setups.

Clients typically work with me when they need:

A Full Stack Laravel Developer who owns 15+ early-stage MVPs scaled to live production

A Laravel developer experienced with deep API flows, payment orchestration, and multi-PSP adapters

A Front-end React developer and Next.js developer for scalable interfaces tied cleanly to backend state

A Node.js developer and Nest.js developer for supplementary high-load services and real-time WebSockets

An AI developer and LangChain developer for autonomous AI agent platform execution and smart data pipelines

API-driven architectures and secure, audit-ready backend systems

My core engineering stack covers:

Back-End: Laravel, PHP, Node.js, Nest.js, Express.js, Supabase Postgres, REST APIs, WebSockets, OAuth, JWT

Front-End: React, Next.js, Angular, Vue, JavaScript, TypeScript, Redux, Tailwind CSS, Material UI, Bootstrap

Databases & Cloud: MySQL, PostgreSQL, MongoDB, Redis, Supabase, Elasticsearch, DynamoDB, AWS (EC2, S3, RDS, Lambda), Docker, CI/CD

Development Mindset: VS Code preferred IDE, Git workflows, clean state layers, and strict KISS, DRY & SOLID principles.

I regularly work on MVP builds and early-stage products, focusing on solid backend foundations and avoiding short-lived prototypes. If you need a developer who can jump into your project, understand the Laravel and React architecture fast, and start shipping immediately, let’s see if it’s a good fit.
