You will get same-day React, Node.js & MongoDB bug fixes and debugging
Project details
2+ years fixing production bugs in React, Node.js, Express & MongoDB apps at Revnosoft real codebases, real APIs, real deadlines. Most freelancers patch the symptom and move on. I trace every bug back to its root cause so it doesn't quietly resurface later in a different form.
Common issues I fix:
Broken or failing API calls
React components that won't render correctly
State management bugs
Authentication & authorization errors
MongoDB/Mongoose schema or query issues
Performance bottlenecks
Every fix is tested before delivery, and I stay reachable if anything related comes up after handoff no disappearing once payment clears.
Send me your bug details and I'll tell you honestly how long it'll take and whether it's something I can solve.

About Muhammad Mahad
Full Stack MERN Developer & Figma UI Designer SaaS, Dashboards & Web
Islamabad, Pakistan - 10:24 am local time
instead of coordinating between a designer and a developer.
Over the past 2+ years I have shipped SaaS platforms, admin dashboards,
REST APIs, and AI integrated tools using the MERN stack at Revnosoft,
working on real production codebases under real deadlines. Alongside that
I design clean, modern UI in Figma, building responsive layouts,
component based design systems, and handoff ready files that translate
directly into code without the usual back and forth.
What I Design
I create SaaS landing pages, marketing pages, and admin dashboard
interfaces that are built around visual hierarchy and conversion. Every
design I produce is fully responsive across desktop and mobile, organized
into proper Figma components with auto layout, and structured so a
developer can build from it without asking questions. I also put together
wireframes, high fidelity mockups, component libraries, and Webflow ready
design files depending on what the project needs.
What I Build
On the development side I build full stack web applications using MongoDB,
Express, React and Node.js. I develop REST APIs and handle third party
integrations including Stripe, OpenAI and other external services. I have
built authentication systems using JWT and OAuth, created SaaS platforms
with subscription and payment flows, and developed AI powered tools using
the ChatGPT and OpenAI API. For deployment I work with Vercel, Railway,
AWS and VPS environments depending on the project setup.
How I Work
I start by understanding your exact requirements before touching design or
code. If the project needs a Figma design first I handle that, get your
approval, and then move into development so nothing gets lost in
translation between stages. I build the frontend and backend in clear
testable stages, test everything thoroughly before delivery, and stay
available after handoff. I do not disappear once payment clears.
Why Clients Work With Me
Having one person handle both design and development removes the handoff
friction that slows most projects down. I bring 2 plus years of real
industry experience from Revnosoft, a Computer Science degree from
Pak-Austria Fachhochschule, and a track record of delivering clean,
maintainable code with clear communication throughout.
Tech and Design Stack
Design tools include Figma, UI UX design, wireframing, prototyping and
design systems. On the frontend I work with React.js, Tailwind CSS,
Bootstrap, HTML5 and CSS3. Backend is Node.js and Express.js. Database
work covers MongoDB and Mongoose. My tooling includes Git, GitHub and
Postman, and I deploy using Vercel, Railway, AWS and VPS.
Send me your project details and I will tell you honestly whether it is a
good fit and exactly how I would approach it.

Revisions may occur after the delivery date.
Review your code and reproduce the bug
I'll go through your codebase, run your app locally, and reproduce the exact issue you're facing before touching anything.
Diagnose the root cause
Instead of just patching the symptom, I trace the bug back to its actual source so it doesn't quietly resurface somewhere else later.
