I help businesses migrate, secure, and stabilize their server infrastructure from database migrations and hosting-panel cutovers to security audits and automated backup pipelines. 100% Job Success on Upwork, including hands-on VPS recovery, high-uptime NginX/LiteSpeed deployments, and multi-month server administration contracts. What I bring: Server & database migrations (cPanel/WHM, Plesk, Hostinger, panel-to-panel cutovers) with zero-data-loss runbooks Infrastructure as Code and container orchestration with Terraform, Kubernetes, Docker, and Ansible; CI/CD pipelines with GitHub Actions and Jenkins WordPress deployment, hosting, and migration (vhost setup, SSL via Certbot, All-in-One WP Migration) Security audits and hardening (firewalls, fail2ban, credential rotation, edge lockdown) Backup engineering (automated offsite backups, S3-compatible object storage, restore-tested pipelines) Linux (RedHat/CentOS/Ubuntu/Debian) and Windows Server administration, virtualization I communicate clearly, work fast under deadline pressure, and document what I fix, clients have called me "diligent," "reliable," and "very honest and professional." Let's talk about what's slowing your infrastructure down.

I architect backend systems that handle real-world scale. From high-throughput APIs to blockchain integrations and AI-driven automation, I build the infrastructure layer that products depend on to grow. With production experience across Node.js and Python, I've designed and shipped backend systems for startups, agencies, and established businesses. My focus is always the same: clean architecture, strong security, and systems that don't break when traffic spikes or requirements change. Backend Architecture and API Development I design RESTful APIs and microservice architectures using Node.js, Express.js, Python, and FastAPI. Every system I build follows clear separation of concerns, proper error handling, and thorough documentation. I handle database architecture across PostgreSQL, MySQL, and MongoDB, with a focus on query optimization, indexing strategies, and schema design that supports long-term growth. Authentication, role-based access control, JWT implementation, and secure data handling are built into every project from day one. Blockchain and Payment Infrastructure I integrate blockchain functionality into backend systems using Ether.js and Web3 libraries, alongside traditional payment gateways like Stripe, M-Pesa, and MTN MoMo. Whether you need smart contract interaction, wallet integration, or multi-provider payment flows, I build payment infrastructure that is reliable and secure in production. AI-Driven Systems This is where my work goes beyond standard backend development. I build intelligent backend systems that integrate LLM APIs, machine learning models, and data processing pipelines directly into production architecture. Recently I built an agentic job matching platform with concurrent API orchestration, intelligent scoring, and real-time recommendations served through a high-performance FastAPI backend. I design AI workflows that are production-ready, not just prototypes. How I Work Every project starts with understanding the business problem, not just the technical requirements. I communicate clearly, ship on schedule, and write code that your next developer can read and extend without a walkthrough. I'm comfortable leading backend architecture from scratch or stepping into an existing codebase and making it better without breaking what already works. Tech Stack: Node.js, Python, FastAPI, Express.js, PostgreSQL, MySQL, MongoDB, Redis, Ether.js, Web3, Docker, Git, CI/CD Collaboration: Slack, Microsoft Teams, Jira, Trello, Asana, ClickUp If you need a backend architect who can own your entire server-side infrastructure and deliver systems that are fast, secure, and intelligent, let's talk.

Tired of spreadsheets that don't scale, or SaaS tools that almost fit your workflow? I build custom ERPs, SaaS platforms, and AI-powered automation using the MERN and PERN stacks, so your business owns its software instead of renting it. Full-stack delivery from database design to secure backend architecture to responsive front-end UIs that teams actually want to use, plus agentic AI workflows that automate the manual work behind the scenes. Recent Work: Built a MERN-based logistics platform integrating DHL Express APIs with a multi-currency pricing engine and fraud-prevention locks. Delivered a PERN emergency response system with PostGIS spatial queries for real-time incident tracking, paired with Flutter field apps. Developed a distribution and inventory platform for a logistics client that cut tracking errors by nearly half and automated the entire invoicing process from order to payment. Client feedback: "Aaraf proved himself to be an excellent programmer with strong problem-solving skills. He developed well-documented APIs for our mobile applications using Node.js, and his PostgreSQL query optimisations were outstanding, ensuring fast API responses even when handling large amounts of data" What I Deliver: ✅ Custom ERPs and inventory systems that replace manual spreadsheet work ✅ MERN and PERN full-stack platforms (React, Node.js, Express, MongoDB, PostgreSQL) ✅ Agentic AI workflows and automation (LLM integrations, autonomous task agents) ✅ REST API development, Stripe/AWS integrations, PostGIS spatial data ✅ Real-time dashboards and role-based multi-tenant systems Industries Served: 📌 Logistics & Supply Chain 📌 Emergency Management & Public Safety 📌 ERP & Business Automation 📌 SaaS & Startup Platforms Why work with me: Real business workflows, invoicing, inventory, order management, dispatch, are already understood, so no time is spent explaining the basics. Complete, production-ready systems are delivered, not half-finished prototypes.
