Custom Work
Experienced developers who specialise in mathematics and performance but work full stack. We work with you directly — no layers of project managers or junior consultants.
Optimisation modelling
Formulate the problem correctly, choose the right constraints, select the solver that fits. Using ojAlgo’s ExpressionsBasedModel, we design solver-agnostic models — no vendor lock-in, and moving to more solving power later never means rewriting.
Model review & performance
Why a model is slow is usually not why people think it is. Investigation, profiling, reformulation and tuning — on models built with ojAlgo or on the systems around them.
Financial systems
Portfolio optimisation, risk management, Black–Litterman implementation, market simulation. We have years of experience building quantitative tools for financial services — ojAlgo was born from this work.
JVM performance
Numerical computing performance tuning, JVM selection, vectorisation, benchmarking. If you are doing heavy computation on the JVM and need it to go faster, we can help.
Fixed-scope engagements
Two sizes, priced before anything starts.
| What it is | Price | |
|---|---|---|
| One day | A single problem looked at properly — a model reviewed, a bottleneck found, an approach validated before you build on it | EUR 1 200 |
| One week | Enough time to change something — reformulate, integrate, benchmark, or build a working prototype | EUR 6 000 |
Prices exclude VAT.
These are timeboxes, not deliverable guarantees. You are buying a day, or a week, of undivided attention on your problem — not a promise that any particular outcome is reachable in that time. We will tell you before we start if we think the box is the wrong size.
Each one ends with something written: what we found, what we would do about it, and what we would not bother doing. That holds its value whether or not you engage us further.
They are arranged by enquiry rather than bought online, because a short conversation is what makes the box the right size.
Larger projects
Anything beyond a week is scoped and quoted individually. Longer full-time commitments are discounted — the day rate above is for short, self-contained work, where the cost is mostly in loading the context.
Everything is quoted before any work starts — you will not receive an invoice you did not agree to in advance.
How to start
New to Optimatika?
Use the contact form. No subscription is needed to ask. Describe the problem and we will scope it from there.
Already have a subscription?
Raise it on the channel you already have — an issue in ojAlgo-extensions reaches us directly. Note that answering questions is included in your subscription; this page is for the work that is not.
Not sure if it is a support question or a project? Ask — we will tell you.
