Hire the Best Ember.js Developers & Programmers
in Pakistan

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. He provided a comprehensive back-end solution and I look forward to working with him in the near future.” ⭐ “Excellent professional, without a doubt one of the best I've seen on this platform! I highly recommend him.” My strongest areas: Frontend: TypeScript, JavaScript, React, Next.js App Router, TailwindCSS, Zustand, Redux Backend: Node.js, Fastify, Express, Bun, REST APIs, authentication, role-based systems, API architecture Databases & Search: PostgreSQL, Supabase, MongoDB, Redis/Valkey, Meilisearch DevOps & Infrastructure: Docker, Docker Swarm, VPS, Hetzner, DigitalOcean, AWS, Traefik, CI/CD, Tailscale, server migration, environment management Automation & Integrations: n8n, Node-RED, webhooks, WhatsApp APIs, Evolution API, Typebot, payment APIs, third-party integrations, background jobs Monitoring & Reliability: Grafana, Sentry, structured logging, error tracking, alerts, deployment hardening I usually work best with clients who need a technical partner, not only a task-based coder. 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.

Most freelancers accept your job, agree to your timeline, miss every deadline, deliver half broken features, disappear when bugs appear, and still call it a "successful project." I do the opposite. With 5+ years building full stack systems, I've shipped multi role dashboards, AI powered applications, and operational SaaS platforms, from robust web applications to advanced AI driven chatbots. I frequently work with MVP builds and early stage startups, ensuring the product is built on a solid technical foundation that scales as the business grows. I'm equally comfortable jumping into existing codebases, quickly understanding what's already built and extending, fixing, or scaling it without disrupting what already works. Whether it's frontend or backend, I work end to end as a full stack developer. I've also completed a Bachelor's in Computer Science. Recent wins: Delivered a $2,850 UI dev project with continuous high-quality work and on-time delivery. Tech Stacks and Expertise: Frontend: React.js, Next.js, HTML5, CSS3, JavaScript, TypeScript Backend: Node.js, Express, NestJS Databases: MongoDB, MySQL, PostgreSQL, Firebase, Supabase, NeonDB, DynamoDB AI & Tools: Vercel AI SDK, OpenRouter, Groq API, Claude API, RAG pipelines using LlamaIndex with Supabase pgvector vector database Let's connect Whether you need a full stack developer, AI agent, MVP or SaaS ERP CRM solution, or custom API automation, I'll deliver a solution that's future proof, scalable, and tailored to your business.
