Is your PHP app slow, stuck on an old version, or running on a badly configured server? I fix exactly that — and build new systems that don't break down the road. I'm Zahid, a Laravel & Symfony specialist with 5 years of experience delivering backend systems for SaaS platforms, government organizations, and international businesses. I don't just write code — I solve the real problems behind your technical requirements. 🚀 𝗪𝗵𝗮𝘁 𝗜 𝗦𝗼𝗹𝘃𝗲 𝗙𝗼𝗿 𝗬𝗼𝘂 🔹 Fix slow applications I identify real bottlenecks — inefficient queries, N+1 issues, missing indexes, poor caching — and improve performance with measurable results. 🔹 Optimize & migrate databases I restructure poorly designed databases, tune slow queries, add proper indexing, and handle full data migrations — across MySQL, PostgreSQL, and Oracle — with zero data loss and full integrity checks. 🔹 Upgrade legacy systems Safe upgrades from PHP 5.x / 7.x → 8.x, Laravel and Symfony upgrades with full compatibility and minimal downtime. 🔹 Build scalable backend systems SaaS platforms, REST APIs, real-time features (WebSockets), and complex business logic designed to scale. 🔹 Integrate payment gateways — I implement secure, reliable payment flows using Stripe, PayPal, Mope payments, and other regional or custom gateways — subscription billing, one-time payments, marketplace payouts, and refund handling all covered. 🔹 Solve server & deployment issues Proper VPS setup, Nginx/Apache configuration, SSL, security hardening, and production stability. 🔹 Clean up messy codebases Refactoring legacy systems into maintainable, structured, and developer-friendly code. 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀 🔹 Laravel & Symfony Development — SaaS, multi-tenant apps, REST APIs, WebSockets, queues, admin panels. 🔹 PHP & Framework Upgrades — PHP 5/7 → 8.x, Laravel 5–12, Symfony version upgrade. 🔹 Performance Optimization — query tuning, Redis/Memcached caching, N+1 fixes, code refactoring. 🔹 Database Optimization & Migration — schema redesign, indexing, query optimization, cross-platform data migration (MySQL, PostgreSQL, Oracle) 🔹 Payment Gateway Integration — Stripe, PayPal, Mope payment, subscription billing, marketplace payouts, webhook handling. 🔹 VPS & Server Setup — cPanel, WHM, Nginx, Apache, SSL, DNS, mail server, firewall configuration. 🔹 Server & Hosting Migration — zero-downtime transfers, database migration, DNS cutover. 🔹 Legacy PHP Modernization — refactoring, security patching, technical debt reduction. 🔹 API & Third-Party Integration — REST APIs, webhooks, Twilio, and custom service connections. 𝗪𝗵𝘆 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗖𝗵𝗼𝗼𝘀𝗲 𝗠𝗲 🔹 Code + Server — One Person I own both the application and the infrastructure it runs on. No gaps between your developer and your sysadmin. 🔹 Government & Enterprise Delivered I've built production systems for government organizations and national enterprises — where reliability, security, and accountability are non-negotiable. 🔹 Performance You Can Measure I don't just say "it's faster." I give you real numbers — query times, page load speeds, server response metrics — before and after. 🔹 Long-Term Code Quality Clean architecture, SOLID principles, and full documentation so any developer can maintain what I build. 🔹 Global Availability Flexible hours covering US, European, and Middle Eastern time zones. 𝗧𝗲𝗰𝗵 𝗦𝘁𝗮𝗰𝗸 🔹 Backend: PHP, Laravel, Symfony, CodeIgniter, REST APIs, WebSockets, Cron Jobs, Queue Workers, Eloquent ORM, Doctrine ORM, JWT Authentication, Mail Integration 🔹 Database: MySQL, PostgreSQL, Oracle DB, SQL, Database Optimization, Database Migration 🔹 Server: VPS, Dedicated Server, Shared Hosting, cPanel, WHM, Plesk, CyberPanel, DirectAdmin, Nginx, Apache, OpenLiteSpeed, Linux (Ubuntu, CentOS, Debian, AlmaLinux), Windows Server, Docker, Kubernetes, Cloudflare, CI/CD, GitHub Actions, Jenkins 🔹 Frontend: React.js, Next.js, Vue.js, JavaScript, Tailwind CSS, Bootstrap, base44 🔹 API & Third-Party: Payment Gateway Integration, SMS Gateway Integration, Chatbot, Geo-Location APIs, Twillo APIs. 🔹 CMS & E-commerce: WordPress, Shopware, Grav CMS Tell me your situation — slow app, broken server, outdated codebase, or a new build.

Senior Web developer with twelve years of experience building web applications in PHP. For the last ten years I have worked with the Laravel framework from version 4.2 to 12 — with over 6,400 hours logged exclusively on Laravel projects here on Upwork. I also work with Symfony and API Platform as part of regular client work. Throughout my Upwork career I have worked on complex and large-scale projects. You can verify that through my completed project history. My primary strength is not writing code — it is the work that happens before code is written. I understand the full software development lifecycle and have applied it as a lead developer across various projects. I take a set of requirements, validate them, turn them into a software model, then break the work into small, well-defined tasks that any competent developer — or an LLM coding tool — can execute cleanly without ambiguity. I have worked extensively with AI coding tools and I know how to get consistent output from them. I use Claude Code, Gemini CLI, and Qwen Code for agentic coding workflows. For in-editor assistance I work with Continue and GitHub Copilot. For local model inference I run Ollama and LMStudio on-device. This is not surface-level familiarity — I use these tools daily and understand where they fail and how to work around that. On the vector and semantic search side I have hands-on experience with pgvector (PostgreSQL), Qdrant, Chroma, Pinecone, and MariaDB vector. I work with PostgreSQL full-text search and understand the difference between keyword, vector, and hybrid retrieval strategies and when to use each. A common misconception is that building AI-powered features requires Python. It does not. Both Laravel and Symfony now have mature tooling for integrating LLMs, building agents, and implementing RAG pipelines directly in PHP. On the Symfony side, I work with the Symfony AI Bundle. It connects to over 25 AI providers through a unified interface, builds autonomous agents with tool use and multi-step reasoning, and integrates with vector stores like Qdrant, pgvector, and Chroma for RAG. It also supports the Model Context Protocol through the MCP Bundle. On the Laravel side, I work with the official Laravel AI SDK and LarAgent. Both support Artisan-generated agent classes, structured output, tool execution, conversation history, and local models via Ollama. If you have an existing Laravel or Symfony application and want to add AI features — a support agent, semantic search, structured data extraction — it can be done entirely within your existing PHP codebase, without adding a Python service. I practice Agile development, specifically Scrum. I write SRS documents, run requirement validation, handle software modelling and architecture design, extract user stories, plan sprints, assign tasks, and review and merge code. I have worked with teams across different time zones throughout my career. I am comfortable with both GraphQL and RESTful API design. For testing I use PHPUnit and am familiar with TDD and BDD approaches. I contribute to open source — my GitHub profile is digitaldreams. I also write technical articles about Laravel, Symfony, and PHP on Medium username is tuhinbepari . Writing forces precision and I find it keeps my understanding of the ecosystem current. Technical stack Languages: PHP, Python, JavaScript, HTML, CSS, SQL Frameworks: Laravel, Symfony, API Platform AI: Symfony AI Bundle, Laravel AI SDK AI tooling: Claude Code, Gemini CLI, Qwen Code, Continue, Copilot, Ollama, LMStudio Vector stores: pgvector, Qdrant, Chroma, Pinecone, MariaDB vector Databases: PostgreSQL, MySQL, SQLite, Elasticsearch CMS: WordPress, Drupal, Statamic Testing:PHPUnit, TDD, BDD
