You will get Codebase Audit, Security & Architecture Review Consultation
Project details
Scaling an existing application without checking its core health can lead to unexpected security breaches and sudden performance drops. Having shipped 20+ products over 7+ years, I help you diagnose hidden vulnerabilities in your Laravel and React stack before they impact your business.
We will inspect your codebase, evaluate database query efficiency, and identify architectural debt. Whether you need to secure authentication layers, clean up server-side boundaries, or optimize heavy traffic paths, we will review it thoroughly. You get an objective security assessment and a clear refactoring plan tailored to your system.
I help teams harden security layers, eliminate structural bottlenecks, and ensure safe code deployment without interrupting live users.
I solve technical bottlenecks in:
• Security vulnerability detection and dependency risk analysis
• Laravel backend architecture and database query efficiency
• Client-side and server-side security boundaries
• Authentication, authorization, and token flow integrity
• Codebase maintainability and strict adherence to best practices
• Performance bottlenecks under heavy production traffic

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.
About Andrii
Full Stack Laravel Developer | React & Next.js Frontend | Node.js PHP
Zaporizhzhya, Ukraine - 9:14 pm local time
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.
