Hello

My name is Zoravar Singh Kalkat. I am a medical doctor, aspiring traumatologist, and programmer from Stockholm, Sweden.

I work across clinical medicine, research, and engineering. I’m particularly interested in trauma surgery, bone infections, and the practical challenges of managing complex cases.

My clinical practice is grounded in evidence-based medicine and I’m interested in integrating bedside diagnostic tools such as POCUS into my future training to improve decision-making and reduce time to intervention.

Alongside this, my research work has pushed me toward programming. Good tooling can fundamentally change how large datasets are handled and understood, so I’ve been building a stronger foundation in software development to support my future work.

Ongoing

Research

• Bone metabolomics study in conjunction with the AO research institute, Riga Traumatology and Orthopaedics Hospital, and the Baltic Biomaterials Center.
• Sexual function during and after endometriosis treatment (exploratory phase).

Projects

• Building a Voron R2 3D printer.
• Developing this website, with plans to expand it into a blog and project log.
• Learning German to a C1 level.

Clinical & Research Work

I have been working in trauma and orthopaedics in Riga, gaining hands-on experience in surgical preparation, assisting in procedures, and post-operative care.

My exposure includes fracture management, infection-related revision surgery, combat-trauma, and reconstructive techniques. Alongside clinical work, I contribute to research in bone infections and metabolomics in collaboration with international institutions.

Programming

I build tools primarily in Rust, focusing on systems-level problems with an emphasis on security and reliability.

• Memfd-Secret
  A Rust crate wrapping the Linux memfd_secret syscall to securely store sensitive data in memory. The underlying memory is zeroed when the secret is dropped, and the crate includes full test coverage with property testing.

• Shumai
  A Linux CLI tool that automatically renews SSL certificates issued by Porkbun and exposes a health server. Built on top my memfd-secret crate.

• This Website
  A static site built with Astro from the ground up, without third-party themes. It features a custom layout system, multilingual routing, and a focus on clean typography and performance.

Hobbies

• Automotive repair (engine, drivetrain) — current project an Audi TT mk2.
• Tinkering and hands-on building.
• River kayaking — with plans to take on the coast.
