Systems & Backends
“It works… until it doesn't.”
Production-grade backends, APIs, and integrations that hold up under real-world load - and tell you when something's wrong.
We build the things you'll still be glad you built years from now.
Rezinaus is a software studio led by Manav - one pair of hands from first sketch to launch and beyond. No bloat, no handoffs, no black boxes.
There's no shortage of tools, templates, and AI-generated starting points. Starting was never the hard part. The hard part is keeping something alive - through real users, real edge cases, real growth - with someone in your corner when it counts.
Where teams get stuck
We've seen these problems before
Web & Digital Presence
“Your site doesn't match who you've become.”
Websites and web apps that reflect where you're going, not where you started.
Apps & Products
“You've validated the idea. Now it needs to be real.”
From working prototype to polished product, without losing the plot along the way.
Creator Infrastructure
“You're running a business on 15 disconnected tools.”
One calm system for creators who've outgrown the free tier.
AI That Actually Ships
“The demo was impressive. Production is a different story.”
AI taken from proof-of-concept to reliable, observable, maintainable systems.
Migrations & Rescue
“You can't stop shipping to fix the foundation.”
Moving to firmer ground without breaking what already works.
How we work
From seed to bloom
Step 01
Listen
We start inside your world - the constraints, the users, the thing that hurts - before we touch code.
Step 02
Sketch
We prototype together, in the open, while ideas are still cheap to change.
Step 03
Build
You see working software every week - progress you can click, not a deck.
Step 04
Grow
Launch is first light, not the finish line. We stay while the thing takes root.
Our principles
What we hold onto
Founder-led, end to end
You work directly with me - no account managers, no junior devs learning on your project. I write the code, answer the questions, and pick up the phone when something breaks.
Boring technology
We choose tools with deep roots: strong communities, proven track records, and engineers who can maintain them long after we're gone. Novelty has to earn its place.
Work we can stand behind
We say no to work that doesn't sit right - no online gambling, no crypto schemes, no engagement traps. We're here for work we can be proud of.
Our work
Things we've built
Law Firm Backend System
A Slack integration and service-syncing system for a law firm - tight budget, tight timeline, still running today.
Backend / IntegrationsNFC Music Player
An app that turns physical NFC cards into album and single plays. The old-school feel of tapes, modern tech underneath.
Mobile App / HardwareTell us what you're working on
No pitch deck needed. Just a conversation between people who care about building good things.
