Mandeep K — Senior Engineer at Felizit, specializing in Angular and React
Founder & CEO
Engineered by

Mandeep K

Senior Full-Stack Engineer · 8 Years

Hi, I'm Mandeep. I've spent 8 years building production web applications in Angular, React, and Node.js — for startups across the US, UK, Canada, and India. From SaaS dashboards and e-commerce platforms to internal enterprise tools, I've shipped over 100 projects, every line of code written by me.

Felizit is my one-person engineering practice. I started it because I believe great web apps come from one senior engineer who actually cares — not from agency layers or rotating junior teams. When you hire Felizit, you hire me, directly. That's the whole point.

Code should be readable. Apps should be fast. Clients should feel calm. Anything less, and I haven't done my job yet.

FAQ

Questions, answered honestly.

Don't see your question? Email us at hello@felizit.com — I reply within 24 hours.

What technologies do you specialize in?+
My primary stack is Angular and React on the frontend, Node.js (Express, NestJS) on the backend, with MongoDB and PostgreSQL for databases. I also work with Next.js, GraphQL, Docker, and deploy to AWS, Vercel, or DigitalOcean depending on what fits the project.
How long does a typical project take?+
A standard business website with 5–10 pages launches in 2–3 weeks. Custom web applications (dashboards, SaaS platforms) typically take 6–10 weeks. I share a clear milestone-based timeline at proposal stage and provide weekly progress demos.
Do you offer fixed pricing or hourly rates?+
All my projects are fixed-price. After a discovery call, I provide a detailed scope and a fixed quote — no surprises. For ongoing work or retainers (maintenance, marketing), I offer transparent monthly packages.
Do I get the source code?+
Absolutely. You own 100% of the source code, designs, content, and deployment access from day one. I use your GitHub or set up a fresh repo under your organization. No vendor lock-in, ever.
Are you a one-person operation or an agency?+
Felizit is my one-person engineering practice. When you hire Felizit, you hire me — Mandeep K — directly. I write every line of code, attend every meeting, and own every decision. This means faster decisions, no account managers, no junior developers, and no agency overhead inflating your invoice.
Do you handle SEO and digital marketing too?+
Yes. While web development is my primary service, I offer SEO, Google Ads, content marketing, and social media as a managed service. Many of my clients hire me for both — the website and the traffic strategy that grows it.
Do you work with international clients?+
Yes. I work with clients across the US, UK, Canada, Australia, the UAE, and India. Communication happens over Slack, email, and Zoom — and I adapt to your timezone for key meetings (flexible US/UK morning hours).
What happens after launch?+
I offer 30 days of free post-launch support to fix any bugs or tweaks. After that, you can choose a monthly maintenance plan (security patches, backups, performance monitoring, content updates) or simply pay-as-you-go for changes.
