Services
What we build and fix
Back-end, performance, integrations and cloud — the parts of your system that really need to hold under pressure.
Cloud & microservices
APIs, background services, queues and observability to move from a monolith to scalable services on Azure — without a risky “big bang” rewrite.
Performance & reliability
Query tuning, caching, async patterns, resilience and monitoring – focused on uptime and fast responses in real production usage.

About
Who is 3NV TECH
3NV TECH is a small engineering studio focused on back-end, cloud and enterprise systems. We like complex domains, integrations and high-availability scenarios – where architecture really matters.
We are not a generic “we do everything” agency. We prefer fewer systems with long-term responsibility, working side by side with your product or IT team.
Engagements usually mix architecture, implementation, code reviews and mentoring. The goal is not only to deliver features, but to leave your system and team stronger.
Backend-first

Contact
Let’s talk about your system
A short, direct conversation is enough to see if we can really help – and if it makes sense to go deeper together.
Tell us briefly: your company, current stack, where the pain is today and what you want to
achieve in
the next 6–12 months.
We usually reply within 1–2 business days.
