Full Stack Developer with hands-on command over the entire stack — from pixel-perfect frontends to hardened production servers. I architect and manage portals, configure and secure Linux/Windows servers, automate deployments, and hunt down the bugs nobody else can reproduce.

99.9% — production stays up. ▊I'm Shahzaib Nagi — a full stack developer who doesn't stop at the code editor. I take a product from an empty repository all the way to a live, monitored, secured production server, and I stay responsible for it after launch.
My core strength is portal development & management: admin dashboards, client portals, order & payment systems, role-based access, reporting panels — built to handle real traffic and real money. On the infrastructure side I set up, harden and maintain servers: Nginx/Apache, SSL, firewalls, backups, cron jobs, CI/CD pipelines and zero-downtime deploys.
And when something breaks at 3 AM, that's where I'm strongest — systematic debugging. Logs, traces, profiling, DB query analysis, network inspection — I find the root cause instead of patching the symptom.
Four pillars — and I own all four end to end, so nothing gets lost between "developer" and "server guy".
Complete web applications — responsive frontends, robust REST/JSON APIs, relational & NoSQL databases, authentication, payments and third-party integrations.
From bare VPS to production-ready infrastructure. I provision, harden, monitor and maintain servers so your app never goes dark.
Admin panels, client portals and internal systems with clean UX and serious permission control — built to be operated daily by real teams.
Inherited a broken codebase? Random 500s? Slow queries? Memory leaks? I diagnose the root cause and deliver a documented, permanent fix.
Representative of the systems I design, build and keep running in production.
Full order lifecycle portal — product management, live order tracking, payment verification, customer records and role-based staff access with an activity audit log.
Bare VPS turned into a secured production stack: Nginx reverse proxy, SSL automation, firewall & fail2ban rules, nightly encrypted backups and uptime monitoring with alerts.
WebSocket-powered analytics dashboard streaming live metrics, with cached aggregation queries and charts that stay smooth even on large datasets.
Diagnosed recurring production 500 errors caused by connection-pool exhaustion and unindexed queries. Root cause documented, fixed and load-tested — no repeat incidents.
Secure client area with document access, invoice history, support ticketing and email notifications — reduced manual support workload dramatically.
Automated build → test → deploy pipeline with staging environment, instant rollback and zero-downtime releases. Manual deploys eliminated completely.
Delivering complete web products for clients worldwide — architecture, development, deployment, and ongoing server & portal management under one roof.
Moved deep into infrastructure — containerisation, CI/CD, monitoring and building large multi-role portals that teams operate every day.
Specialised in backend systems and became the person teams call when production breaks — profiling, tracing and permanently fixing critical issues.
Started with HTML, CSS and JavaScript — obsessed with clean, responsive interfaces. That foundation still shapes everything I build.
We talk through the goal, the users and the constraints. I ask the hard questions early so nothing surprises us later.
Stack selection, database schema, server plan and a clear milestone breakdown with realistic timelines.
Clean, modular code with regular demo builds so you see progress instead of waiting in the dark.
Secured server, SSL, backups, monitoring — then I stay available for fixes, updates and scaling.
Full stack web development, Linux server setup and management, portal development and management, and advanced debugging or rescue work on existing production systems. I cover the entire lifecycle — from an empty repository to a monitored, secured live server.
Yes. I provision and harden Linux servers, configure Nginx, SSL, firewalls and backups, set up CI/CD pipelines and uptime monitoring, and keep maintaining the infrastructure after launch. You don't need a separate DevOps person.
JavaScript, TypeScript, React, Next.js, Node.js, PHP, Laravel, MySQL, PostgreSQL, MongoDB and Redis on the application side — plus Linux, Nginx, Apache, Docker, AWS, DigitalOcean, Cloudflare and GitHub Actions on the infrastructure side.
Yes — freelance, contract and retainer engagements, working remotely with clients worldwide. I usually respond within a few hours and can start with a short paid discovery phase if the scope isn't fully defined yet.
Absolutely — this is one of my strongest areas. Production incident triage, performance and database query profiling, legacy code refactoring and security fixes. I find the root cause, fix it permanently, and document what went wrong so it doesn't repeat.
Send me the details through the contact form below. We discuss the goal, users and constraints, then I put together an architecture plan with clear milestones and timelines before any code is written.
Tell me what you need — a new build, a server rescue, or a portal that finally works properly.
