Understand
We start with the problem, the constraints and the deadline that genuinely matters. If we think you're solving the wrong thing, you'll hear it before you spend money.
Software engineering studio · Bratislava
Small team.
Serious software.
Sinorom designs, builds and runs production systems for companies that want the work done properly — scoped honestly, written by the people you actually talk to, and handed over in a state you can maintain.

Services
Four things we do, and do properly.
Most engagements start in one of these and grow into another. We are happy to own the whole lifecycle — or just the part your team can't cover right now.
Custom software development
Products, platforms and internal tools — built to spec and built to last.
Most of our work begins with a business problem rather than a finished specification. We scope it properly, agree what “done” means in writing, and then build the thing: a real application with tests, documentation and a deployment story — not a prototype you have to throw away in six months.
- Web applications and internal platforms
- APIs, integrations and third-party connectors
- Legacy replacement and incremental migration
- Database design, modelling and performance work
- Automated testing and CI pipelines
- Documentation and clean technical handover
Typical engagement — a fixed-scope project, or a continuous build on a monthly retainer. Code lives in your repository from the first commit.
Cloud, DevOps & infrastructure
The unglamorous half of shipping software, done without shortcuts.
Software that isn't deployed, monitored and backed up isn't finished. We build the infrastructure your application actually needs — no more, no less — automate the parts that should never be manual, and leave you with a system your own people can operate without calling us first.
- Linux provisioning, hardening and patching
- Docker and container orchestration
- CI/CD pipelines on GitLab CI or GitHub Actions
- Nginx, TLS certificates and reverse proxying
- Monitoring, alerting and log aggregation
- Backups, restore tests and recovery drills
- Infrastructure as code and repeatable rebuilds
- Hosting cost review and right-sizing
Typical engagement — a one-off build with full handover, or ongoing managed operations with an agreed response window.
AI & data engineering
Language models and data pipelines, pointed at problems worth solving.
We build AI features that survive contact with production: grounded in your own data, measured against real cases, and with sensible behaviour when the model gets it wrong. And because most AI work turns out to be data work, we are equally happy repairing the pipeline underneath it.
- LLM integration and retrieval-augmented generation
- Document processing, extraction and classification
- Back-office and workflow automation
- ETL pipelines, warehousing and reporting
- Evaluation harnesses and output quality monitoring
- Self-hosted and EU-resident deployment options
Typical engagement — a short discovery spike to prove the value, then a scoped build once the numbers justify it.
Consulting & technical partnership
A senior engineer in the room when the decision is expensive.
Sometimes you don't need another pair of hands — you need someone to tell you whether the plan is sound. We review architectures, sanity-check vendor proposals, and take on longer-term advisory work for teams that have outgrown decisions made on the fly.
- Architecture and code review
- Technical due diligence before an investment or acquisition
- Fractional CTO and advisory retainers
- Vendor, platform and build-versus-buy selection
- Mentoring and review practice for in-house teams
- Security posture and dependency audits
Typical engagement — a half-day review with a written summary, or a recurring monthly retainer with a standing call.
Work
Products we've built and run ourselves.
Client work is mostly under NDA, so here is the next best evidence: our own products, in production, on infrastructure we operate. Everything below was designed, built and deployed in-house.
Duckerhub
LivePocketBase backends on demand — database, auth, file storage and realtime on your own subdomain. Sleeps when idle, wakes on request.
Jipidy Grid
LiveCross-browser visual testing. Screenshots, visual regression and scripted flows on Chromium, WebKit and Firefox — desktop to phone — from one API call.
Golem
LiveDescribe what you want and Golem turns it into a working website, app or product — with an agent that can hand work to other agents.
eBVB
LiveA market-intelligence platform for the Bucharest Stock Exchange — real-time quotes, order-book depth and a screener. Romanian-language.
DBlicious
In developmentPostgreSQL and MySQL, unbundled — upstream database compute separated from durable write-ahead logs and immutable S3-compatible storage. Our current deep-infrastructure project.
Approach
How an engagement actually runs.
No discovery theatre and no open-ended hourly drift. Four stages, and you can stop after any of them.
Scope
You get a written proposal: what's included, what deliberately isn't, what it costs and when it lands. Changes are re-quoted rather than absorbed silently.
Build
Short cycles, working software you can click on, and a direct line to the person writing the code. Everything sits in your repository from day one.
Operate
We deploy it, watch it, and hand over documentation someone else could act on. If you'd rather we kept running it, that's a separate, honest line item.
Stack
Tools we reach for.

About
A small shop, on purpose.
Sinorom is deliberately small. There is no bench to keep busy, no account-management layer, and nobody assigned to your project who wasn't chosen for it. That means we take on fewer engagements than a larger agency would — and the ones we take on get senior attention from the first call to the handover.
We work with founders, product teams and IT departments around the world — usually remotely, and used to running a project across time zones. We're comfortable being your only technical partner, and equally comfortable slotting in alongside a team that already knows what it's doing.
“Write it down, price it honestly, build it once, and leave the client able to run it without you.” — how we scope every engagement
