Monads & Abstractions

Senior engineers for your hardest software problem.

Consulting and delivery: production AI, the backend it runs on, code assessments, firmware and device software. Scoped in writing, built by the engineers you talk to.

SCROLL

01 — Production AI

AI that ships.

Features behind flags, evaluated on real data, with fallbacks when a model is wrong. Built with senior engineers and a gated agent fleet.

Builder is never the verifier.

Every change is specified, built in isolation, checked by an independent gate, and only then merged. You get the trail, not a black box.

Your repo. Your code.

Provider-agnostic: the right model for each step. No lock-in; your team owns everything at the end.

Work with us

Consulting first: senior engineers on your problem.

Most of our work starts as a consultation: one problem, scoped in writing, solved by the engineers you spoke to.

01 · A call

Tell us the problem: a product to build, a codebase to assess, an AI feature to ship. A senior engineer listens, not a salesperson.

02 · Written scope

Scope, plan and price in writing in our first reply. Fixed-scope phases; we do not bill hourly.

03 · The work

Senior engineers and our gated agent fleet, in your repo. Every change specified, built, independently checked.

04 · Handover

You own the code, the docs and the evidence. Monthly support if you want it, cancel any month.

Services

Tools we built for ourselves, then shipped.

jevx

Decision checks inside your coding agents: guardrails, claim checks, memory.

Open source →

openjevx Server

The open-source OpenJevX inference server, for your own AWS account.

Open source →

pgbx

Postgres backups you own: create a database and it is backed up to your S3.

Open source →

CallBox case design, 3D render

Atoms.

Small devices that give software and AI agents a body in the real world. One job each, done well.

CallBox, the first atom.

A small box with your own SIM. Your software or an AI agent makes and answers real calls and texts, at a flat cost instead of per minute.

Working prototype. Founder batch open.

Real calls and SMS on a SIM today. Early access for the first batch.

Software for electronics

Firmware, operating systems, and the software between device and cloud.

Custom firmware and OS for ESP32

Firmware built for your board: drivers, connectivity, over-the-air updates, and a small OS layer your product logic runs on.

Custom Android OS builds

Android built for a device, not a phone shop: stripped down, locked to your app, with your own update channel.

Device to cloud

The link between the device and your backend: protocols, provisioning, fleet updates and telemetry.

AI on the device

Agents that drive real hardware through a narrow, checked interface, never raw access.

FAQ

Frequently asked questions.

What does Deemwar do?

Deemwar is a software engineering studio. We build production AI features, ship backend infrastructure, review code, and train teams.

What stacks do you work in?

Go and Spring AI / Java backends. React and Vite frontends. Postgres + pgvector for AI-aware data. Python workers on PGMQ for queue-driven work. Kamal for container deploys, OpenTelemetry for observability.

Do you train teams?

Yes, on request: hands-on sessions for engineering teams, for example on Spring AI and on using coding agents well.

How do you price work?

Engagement-based. Fixed-scope phases for builds and assessments; separate monthly engagement for production support. We do not bill hourly. Each engagement is scoped and quoted in writing before it starts.

Where do your systems run?

Production deployments run on Cloudflare-fronted Hetzner servers, with Kamal-managed containers, WireGuard private networking, and pgvector-backed Postgres. We also do GCP deployments on request.

Can you sign an NDA?

Yes. Our engineering partnership with a Netherlands-based AI company ran under NDA, so the client is not named on this site.
