Need a developer who can handle the frontend, backend, database, Docker deployment, VPS setup, and production issues without needing five different freelancers? I am a Top Rated Full-Stack Developer with strong backend and DevOps experience. My work usually sits at the intersection of full-stack development, backend architecture, server deployment, automation, and production support. What I can help you with: ✅ Build full-stack SaaS platforms, dashboards, admin panels, and internal tools ✅ Design backend APIs, database schemas, authentication, roles, and integrations ✅ Migrate Lovable/no-code MVPs into maintainable custom applications ✅ Deploy apps on VPS/cloud using Docker, Traefik, Supabase, CI/CD, and monitoring ✅ Move projects between servers, hosting providers, or self-hosted environments ✅ Fix production issues, optimize performance, and stabilize existing codebases ✅ Build automation workflows using n8n, Node-RED, webhooks, WhatsApp APIs, and third-party APIs Recent client feedback: ⭐ “Shahid successfully migrated the project from Lovable to a self-hosted VPS environment and handled the deployment professionally. Everything was configured cleanly, performance was stable, and communication was excellent throughout.” ⭐ “Shahid was great to work with. He communicated clearly, completed the required work professionally, and was very dedicated throughout the project. He was responsive, reliable, and handled everything with care.” ⭐ “Very professional and easy to work with.

I can join an existing team, work with project managers/designers, or independently take ownership of a feature, backend, deployment pipeline, migration, or complete product module. Clients usually hire me when they need: • A SaaS or web app built from scratch • A backend/API system designed properly • A frontend connected cleanly to real backend logic • A Docker/VPS deployment setup • A Lovable MVP migrated to custom code or self-hosted infrastructure • A broken or messy project stabilized • An automation system using n8n, Node-RED, APIs, or webhooks • Long-term technical support for an existing product My working style is clear communication, practical architecture, clean implementation, and production-focused delivery. I care about building systems that are maintainable, scalable, and understandable after launch. Contact me for a project audit, technical consultation, roadmap, migration, DevOps setup, or full-stack development support.
