What we build and fix

Back-end, performance, integrations and cloud — the parts of your system that really need to hold under pressure.

⚙️

Legacy system modernization

From old .NET Framework or on-premise systems to modern, testable and maintainable architectures that your team can evolve with confidence.

.NET 6–8 Clean architecture Refactoring
☁️

Cloud & microservices

APIs, background services, queues and observability to move from a monolith to scalable services on Azure — without a risky “big bang” rewrite.

Azure Kubernetes Messaging & queues
📊

Performance & reliability

Query tuning, caching, async patterns, resilience and monitoring – focused on uptime and fast responses in real production usage.

SQL & NoSQL Logging & metrics Resilience patterns
Showcase

A real system, built and running

FactoryFlow is our production-control platform for manufacturing shop floors: work orders, a live production board and quality inspection, with access by role. These are real screens from the running system, not mockups.

The business

Manufacturers running orders on spreadsheets and paper get one place for production, inventory and quality.

The workflow

Created, scheduled, running, paused, inspection, completed — with history and pause reasons on every order.

Ready to adapt

A working base we tailor to your process, so you start from a running system instead of a blank page.

AI Assistant

AI that answers from your own documents and data

A working prototype: ask a question in plain language and get an answer from your policies and your database, with the sources shown, access limited by role and every question audited. Demo with a fictitious company.

    Your sources

    Word, PDF and Markdown documents, plus your SQL database.

  2. 2

    Role-aware retrieval

    Search and data tools see only what the signed-in role may see.

  3. 3

    AI model

    Writes the answer from the retrieved content, in the user’s language.

  4. 4

    Answer and audit

    Sources are shown, and every question is logged.

Your documents

Policies, playbooks and contracts are indexed and searched, and each answer points to the section it came from.

Your data

The model never writes SQL. The scope of each query is computed in code from the signed-in role.

Your rules

The role comes from the signed token, never from the request, and every question goes to an insert-only audit log.

Prototype with fictitious data. In a real project we would add single sign-on and masking of sensitive data, and connect your own sources.

Process

How we work with your team

Clear, technical and business-aware. No buzzword show, no magic – just engineering and communication.

01
Discovery & mapping

We understand your domain, flows, current architecture, tech stack and main pain points — so we know where to start safely. You get: a clear picture of risks and quick wins.

02
Architecture & roadmap

We design a realistic target architecture and a step-by-step roadmap that your internal team can follow and review. You get: priorities and a plan you can budget for.

03
Implementation in iterations

We ship new APIs, services or refactors in small increments, with tests and monitoring, keeping the business running. You get: working software every few weeks, not a big-bang release.

04
Monitoring & evolution

Logs, metrics and real usage guide the next improvements in performance, reliability and developer experience. You get: fewer surprises and a system that keeps improving.

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.

What this means for you: fewer surprises in production, a codebase your team understands, and a single accountable engineering partner for businesses that want to grow without rewriting everything.
