Full Stack Developer is needed in Sofia, United States.

Client: DevFixr

Location: Sofia, MH, in

Contract: Freelance

Job Description

This is a remote position.

We are seeking a Mid-Level Full-Stack Developer to join our engineering team during an exciting period of architectural evolution. You will play a key role in transitioning our existing platform from a Laravel-based stack to a modern, high-performance Next.js and PostgreSQL environment. This role is perfect for a developer who is strong in React but wants to deepen their “full-stack” muscles by handling API logic, data integrations, and complex system migrations.

Key Responsibilities

• System Analysis: Dive into our current Laravel solution to understand existing modules, integrations, and dependencies to ensure a smooth transition.
• Migration Execution: Assist senior leads in defining the migration strategy—identifying which components to bridge, replace, or move incrementally.
• Feature Development: Build new, full-stack functionality using Next.js, including both polished UI/UX components and robust backend/API logic (via Next.js API routes).
• Data & Logic Integration: Work with PostgreSQL data models and migrate business logic from PHP/Laravel over to the new TypeScript/Next.js environment.
• Code Quality: Write clean, maintainable, and testable code. You will also assist in optimizing CI/CD workflows for the new stack.
• Collaborative Delivery: Partner with designers, QA, and other developers. You’ll participate in code reviews, document your decisions, and help maintain architectural standards.
• User Continuity: Ensure that the migration happens with minimal disruption to our current user base, supporting the platform until Next.js becomes the primary driver.

Requirements

• 2–4 Years of Professional Experience: A solid foundation in modern web development.
• React & Next.js Expertise: Proven experience building applications with React; familiarity with Next.js server-side logic is a major plus.
• Database Skills: Strong working knowledge of PostgreSQL and relational data modeling.
• PHP/Laravel Awareness: While this is a Move-to-Next.js role, you must be comfortable reading and analyzing Laravel code to understand how to migrate it.
• Communication: Great English communication skills are essential for coordinating across remote teams and time zones.
• Reliability: Ability to work remotely while maintaining high visibility on progress and blockers.

Benefits

• Time Zone: You must be available to coordinate and work within UK business hours.
• Flexibility: Fully remote role with a focus on clear documentation and team synergy.
• Growth: Exposure to high-level architectural decisions and a structured migration roadmap.
