45 → 8minutes per deploy
Dockerized CI/CD pipeline
Rebuilt releases around Docker and GitHub Actions — deploys went from 45 minutes to under 8, saving about three engineering hours per release.
Full-stack engineer with a DevOps streak — I build the product, the API behind it, and the Linux, Docker and CI/CD setup that keeps it fast and online for real users.

Huzaifa (Muhammad Huzaifa Abdulahad) — Full-Stack Software & DevOps Engineer
( About me )
I'm a full-stack engineer who also owns what happens after the merge — the Linux servers, containers and CI/CD pipelines that get code to production, and keep it there.
I've built NestJS and PostgreSQL APIs serving 10,000+ monthly users at 99.9% uptime, cut a 45-minute deploy to under 8 minutes with Dockerized CI/CD, and made legacy apps 30% faster. I still get a kick out of every green pipeline.

x80graphics
Building modern web applications end to end for
businesses that need them to just work. I own the
full lifecycle — architecture, backend and frontend,
APIs and integrations, and the Linux servers and
CI/CD pipelines they ship through.
2023 - 2026
InvoTechLab
Led backend engineering for two SaaS products —
NestJS, TypeScript and PostgreSQL APIs serving 10,000+
monthly users at 99.9% uptime and $40K+ in monthly revenue.
I built Dockerized CI/CD on GitHub Actions that cut deploys
from 45 minutes to under 8, made legacy queries 30% faster
with zero production incidents in 12+ months, and shipped
an IVR workflow that automated 40%+ of inbound calls.

Globewyze
Software Engineering Intern, gaining hands-on experience
building and improving production-ready web and mobile
applications. I worked closely with the development team
to implement features, integrate Stripe payments, and
understand real-world application architecture and APIs.
The experience strengthened my problem-solving, debugging,
and software development skills while teaching me how
professional engineering teams build and ship products.

- 01Full-Stack Engineering10 capabilitiesI build complete products around real business requirements —React and Next.js frontends, Node.js and NestJS backends, the APIsbetween them and the databases underneath, typed end to end.
- 02DevOps, Cloud & Linux8 capabilitiesI own the path from commit to production — Linux servers, Dockerimages, CI/CD pipelines and cloud infrastructure that keep releasesfast, repeatable and boring in the best way.
- 03AI & Business Automation8 capabilitiesI automate repetitive workflows and connect systems so businessescan operate faster with less manual effort. I combine APIs, AI,cloud services, databases, and workflow automation into reliable systems.
- 04Product & Technical Strategy8 capabilitiesGood software starts with good decisions. I help turn ideas intopractical technical solutions by balancing architecture, developmentspeed, scalability, maintainability, and long-term business value.
( My philosophy )
Great software starts with the right engineering decisions. I focus on understanding the problem first, then designing the architecture, choosing the right technologies, and building solutions that are reliable, maintainable, and ready to scale.
Field notes from production — Node.js backends, DevOps and payments, written up so you can use them.

I’m Muhammad Huzaifa Abdulahad (Huzaifa), a full-stack software and DevOps engineer based in Islamabad, Pakistan, building software professionally since 2022. I build SaaS products end to end — React and Next.js frontends, Node.js and NestJS APIs on PostgreSQL — and run them on Linux, Docker, AWS and CI/CD. I’m currently a software engineer at x80graphics.
Four kinds of work: full-stack engineering (web and mobile apps, APIs and SaaS products), DevOps, cloud and Linux (Docker, CI/CD with GitHub Actions, AWS, Nginx and monitoring), AI and business automation (n8n workflows, AI-powered features and integrations), and product and technical strategy (architecture, MVPs and codebase reviews).
TypeScript and Node.js with NestJS and Express on the backend; React, Next.js and React Native on the frontend; PostgreSQL, MongoDB and Redis for data; Docker, Nginx, GitHub Actions and Kubernetes for delivery; and AWS (EC2, S3, CloudWatch and API Gateway) to run it all. I also integrate Stripe payments, real-time updates over WebSockets and Server-Sent Events, and the OpenAI API.
At InvoTechLab I led backend engineering for two SaaS products: NestJS and PostgreSQL APIs serving 10,000+ monthly users at 99.9% uptime, Dockerized CI/CD on GitHub Actions that cut deploys from 45 minutes to under 8, and an IVR workflow that automated 40%+ of inbound calls. Book My Barber, a booking platform I built, handles 200+ appointments a day across 5+ branches.
Yes. I take on a limited number of projects at a time, from MVPs to scaling an existing product. Email mhuzaifaa.dev@gmail.com with what you’re building and we’ll map out the right solution together. I’m in Islamabad, Pakistan (PKT, UTC+5).
