What We Do

Bespoke software, AI agents, private AI, engineering enablement, embedded engineers, infrastructure and modernization - one engineering standard behind all of them

AI Solutions & Agents

We build AI into your product and processes - agents, answers from your own documents, automation and generative features - with whichever model fits: OpenAI, Anthropic, Google or open-weight.

View details

Forward-Deployed Engineering

Our senior engineers work inside your operations, learn how the work is really done, and ship software against your actual workflows. Remote by default, on-site for up to a month.

Bespoke Software Engineering

We turn a business problem into working software - web, desktop, mobile or backend - and choose the stack for the problem, not the other way round. 200+ projects since 2017.

View details

Private & Local AI

We run AI models on your own servers or hardware, so sensitive data never leaves your control - for GDPR, regulated industries and anyone who cannot send data to a US cloud.

View details

AI Engineering Enablement

We help your developers use coding agents safely and productively - with the tools and process we use on our own work: independent multi-vendor review, human approval gates, and credentials agents never see.

Software & SaaS
Multi-Tenant SaaS Platform

A SaaS serving many companies had to take payments correctly when two customers check out at once, and keep each company's data sealed off. We hardened checkout against double processing, enforced tenant separation on the server and caught corrupted translations before users did.

Payment Gateway

A complete online and in-person payment infrastructure for an Angolan fintech startup, built on .NET and Azure by a 10-person RemSoft.Dev team over two years - now processing transactions across 25 banks.

Sales CRM for Gmail and Outlook

For a US sales-technology startup, a 12-person team built email plugins for Gmail, Chrome, Outlook and Office 365, iOS and Android apps, and two web applications - a CRM that let sales reps work four times faster, over a four-year engagement.

How we work

From first call to working software

No surprises: you see the scope and the price before work starts, and the work itself while it happens.

  1. A short call about the problem

    Tell us what the business needs. We come back with how we would solve it.

  2. A written proposal

    Scope, timeline and price in writing - work starts only after you approve it. AI projects usually begin with a short, fixed-scope AI discovery.

  3. Your team in about two weeks

    A project manager is your single point of contact from day one.

  4. Regular demos, visible progress

    Demos and time tracking you can inspect. Every change is reviewed by other vendors' AI models and approved by a senior engineer.

  • Plan reviewed before code is written
  • Diff reviewed by other vendors' models
  • Every finding and decision recorded
  • Works inside Claude Code, Cursor and Codex
  • Free and open source (MIT)

Frequently Asked Questions

Direct answers about how we work

What does RemSoft.Dev do?

RemSoft.Dev is a remote software engineering company that has solved business problems with software since 2017, with 200+ projects delivered. We build web, desktop, mobile and AI systems in the stack each problem needs, across seven services: bespoke software engineering, AI solutions and agents, private and local AI, AI engineering enablement, forward-deployed engineering, cloud, DevOps and on-premise infrastructure, and legacy modernization. The company is based in Vienna, Austria, with engineering primarily in Ukraine.

How do you make sure AI-written code can be trusted?

Every plan and every code change passes three checks. AI agents write and test the code. Models from other vendors - Codex, Gemini, a second Claude or a local model - review the plan before coding and the changes after, through our ConnectOtherAIs review gate. Then a senior engineer approves the result. Across 1,087 review rounds, reviewers from different vendors overlapped on only 5-9% of their findings, so each one catches problems the others miss. You receive normal, tested, reviewable code.

Which technologies do you work with?

We choose the technology for the problem. .NET is where our experience runs deepest and appears in most of our published case studies. Our published work also uses Rust, Python, TypeScript, Angular, React, Svelte and Node.js, on Azure, AWS, Google Cloud or your own servers. For AI we are model-agnostic: OpenAI, Anthropic, Google, or open-weight models running locally through Ollama, vLLM or ONNX.
