About Devsort
Clinical-grade data science and software engineering — from Islamabad.
We are a Pakistan-based team that builds technical systems under the kind of constraints most software companies never encounter — regulatory certification, legacy codebases in production clinical environments, and zero tolerance for output deviation.
We started by doing the hardest kind of work first.
Devsort’s defining engagement was not a greenfield product build. It was a certified clinical algorithm system — six algorithms for monitoring bradykinesia, dyskinesia, and tremor in Parkinson’s disease patients — already cleared by the FDA under 510(k) certification, already running in production, and already generating clinical data for real patients. The problem was the code underneath it.
The implementations were spread across legacy codebases in C/C++, Julia, TCL, and Java — written by different teams over different years, with minimal documentation and no unified architecture. The FDA certification was tied to the existing implementation. Any change, even a refactoring that produced identical outputs, had to be formally assessed before deployment. The algorithms were effectively frozen.
Over 2.5 years, working with PKG Health (now Empatica), we refactored all six algorithms into production-quality Python with full documentation and a validation framework that ran both the original and new implementations against every clinical dataset. Every output was compared. Every deviation was documented and assessed against the clinical tolerance. The refactored suite now runs on five device platforms — Apple Watch, Samsung Galaxy Watch, Sony SmartWatch, Empatica E4, and ActiGraph — with a preprocessing pipeline that normalises hardware differences transparently.
That engagement is how Devsort thinks about technical work. Constraints are not obstacles to work around — they are the specification. Doing the work correctly means understanding exactly what “correct” requires, documenting the evidence, and producing output that holds under scrutiny.
What we believe.
Offshore talent is a structural advantage, not a compromise.
A team in Islamabad that has validated FDA-compliant algorithms is not inferior to a team in San Francisco doing the same work — it is the same quality at a different price point. The question is whether the quality is real. The PKG Health engagement answers that question. Six algorithms. Five device platforms. Three regulatory standards. Two-and-a-half years. Real patient data.
Technical credibility is built by doing the hardest projects, not the easiest.
Our algorithm work for PKG was not the most commercially obvious project to take on. It was slow, high-stakes, and technically demanding in ways that are difficult to communicate in a sales deck. The decision to take it and do it well — over 2.5 years — is the reason the credential exists. We are not interested in the kind of project where acceptable output is easy. We are interested in the kind where it is not.
Documentation is part of the deliverable.
The PKG codebase was undocumented when we received it. Nobody on the client team fully understood all of it. The refactored output was fully documented — in language that a clinical reviewer, not just a developer, could follow. Documentation is not a bonus feature added if time permits. It is a professional standard. Code that cannot be reviewed is code that cannot be trusted.
The team.
The core team comprises data scientists, SQA engineers, embedded firmware developers, and web and mobile engineers — disciplines that rarely sit in the same company because their output requirements are so different. At Devsort they do, because the projects we take on tend to cross those boundaries. A wearable algorithm system is simultaneously a signal processing problem, an embedded deployment problem, and a regulatory documentation problem.
We also have a representative in Melbourne, Australia, which helps us work effectively with AU-based clients across time zones. Australian clients have found the overlap practical — PKT and AEST have workable shared hours, and having a local point of contact for initial conversations reduces the friction of engaging a Pakistan-based team.
