Systems & Backends
"It works... until it doesn't"
Production-grade backends, APIs, and integrations that handle real-world load.
We build the things you'll still be glad you built a year from now
Rezinaus is a software consultancy led by Manav — partnering with founders, teams, and creators to build technology that works as hard as you do. No bloat, no handoffs, no surprises.
There's no shortage of tools, templates, and AI-generated starting points. The hard part was never starting. It's building something that holds up under real users, real edge cases, and real growth — and having someone in your corner when it does.
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.
Creator Infrastructure
"You're running your business on 15 disconnected tools"
Unified systems for creators who've outgrown the free tier.
AI That Actually Ships
"The demo was impressive. Production is a different story."
AI from proof-of-concept to reliable, maintainable systems.
Migrations & Rescue
"You can't stop shipping to fix the foundation"
Moving to better infrastructure without breaking what works.
How we work
From seed to bloom
Step 01
Listen
We start by understanding your world, not pitching ours
Step 02
Sketch
We prototype together, in the open, before committing to code
Step 03
Build
You see working software every week, not a big reveal after 3 months
Step 04
Grow
Launch is the beginning of the relationship, not the end
Our principles
How we're different
Founder-led
You work directly with me. No account managers, no junior devs learning on your project. I'm the one writing the code, answering your questions, and picking up the phone when something breaks.
Boring technology
We pick tools with strong communities, proven track records, and engineers who can maintain them after we leave. We're not chasing frameworks.
Principled work
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
Built and deployed a Slack integration and service syncing system for a law firm — tight budget, tight timeline, still running.
Backend / IntegrationsNFC Music Player
An app that turns physical NFC cards into album and single plays. Old-school feel of physical 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.
