One person, doing the actual work.
No account managers, no subcontracted analysts. When you work with Cortessa, you work directly with the person who runs the analysis.
Hi, my name is Taha Ahmad.
I graduated in Biology from METU and am currently pursuing an M.Sc. at TUM School of Life Sciences. Along the way, I've gained experience across both academia and industry, working on projects in computational biology, bioinformatics, biotechnology, and scientific software development, including R&D at Ankara University Biomedical Engineering and industry experience at BIOMATEN, METU's biomaterials research center.
I started Cortessa because I genuinely enjoy using computation to solve biological problems. Whether it's analyzing sequencing data, building reproducible workflows, developing scientific software, or creating research-focused digital platforms, my goal is always the same: to deliver work that is technically sound, practical, and genuinely useful.
Cortessa is an independent consultancy, and every project is handled personally—from the initial discussion to the final deliverables. I intentionally take on a limited number of projects so that each client receives the time, attention, and quality their work deserves.
Fixed scope, fixed price. No surprises.
The starter price reflects where the business is right now, not the ceiling of the work — it's an early-stage rate that moves up as the track record grows, and locking it in now is the advantage of starting early with Cortessa.
- QC & preprocessing
- Core statistical analysis
- 5 publication-ready figures
- Plain-language written summary
- One round of clarifying revisions
Exact price depends on dataset size and analysis type — confirmed in writing before work starts.
- Multi-dataset or multi-omics integration
- Extended statistics or a custom pipeline
- Manuscript-length written interpretation
- Timeline set to match the scope
Price and timeline are worked out together after a short conversation about what you need — same fixed-scope principle, just sized to a bigger project.
A fixed, predictable process.
No open-ended hours. You know the scope and the price before we start.
Share your data
Send the dataset and the question you're trying to answer — no need to pre-clean it.
Fixed-scope quote
A flat price for a defined deliverable, confirmed before any work begins.
Analysis & figures
QC, analysis, and publication-ready visuals delivered within about a week.
Plain-language summary
A written interpretation so the result is usable, not just technically correct.
Early feedback from real projects.
Not sure if we're a fit?
Cortessa is deliberately narrow. That's not a limitation — it's the point.
We're a good fit if
- You're a researcher, PhD/MSc student, or PI with a dataset that needs proper analysis and interpretation
- You're a lab or early-stage biotech team that needs your research presented credibly online
- You need scientific writing that survives a reviewer's or investor's scrutiny
- You'd rather have one accountable person than a rotating agency team
We won't take on
- Generic web design, marketing sites, or e-commerce builds
- Social media management or SEO campaigns
- Open-ended hourly work with no defined scope
- Bespoke custom design work outside the science-site template
Things people usually ask before starting.
Just tell us upfront — most academic clients pay via a lab purchase order or invoice rather than a personal card. We'll confirm your institution's process before quoting, and issue a formal invoice that fits it. If your university's PO process takes a few weeks, we'll plan the timeline around that rather than assuming a same-week start.
Yes. QC and preprocessing are part of the Analysis Starter Package, not a prerequisite for it. Send the data as it exists — raw, messy, partially labeled — and the cleanup happens as step one, not something you need to solve before reaching out.
Yes, happily, especially for unpublished data or pre-patent work. It's normal to ask, and we'll sign before any dataset changes hands if you'd like one in place.
Most commonly RNA-seq and other NGS data (FASTQ, BAM, count matrices), along with standard tabular formats (CSV, TSV, Excel) for other omics or experimental data. If you're not sure your format is supported, ask — it's a five-minute answer either way.
That happens, and it's not a failure — it's often the actual finding. The written summary will say so plainly, and one round of clarifying revisions is included if you need the analysis extended or re-framed around a follow-up question.
No — this is a paid service, not a collaboration seeking authorship. If your contribution standards call for acknowledgment given the scope of analytical work involved, that's entirely your call to make.
Yes — all work is remote, and most communication happens over email or a short call. Time zones are rarely an issue given the project turnaround is measured in days, not hours.
Then you'll be told that directly, ideally before any money changes hands. Generic web design, marketing work, and open-ended consulting are explicitly outside scope — see the section above — and it's more useful to say so early than to take on a project outside real expertise.
Have a dataset that needs a clear answer?
Tell us what you're working with — we'll tell you honestly whether we're the right fit.
