Software engineer with 30+ years building production-ready business applications and 3+ years as a core database engineer building high-performance RDBMs.

Founder and principal engineer of small ISV with a long track record of owning complex systems end-to-end, from low-level design to production reliability. Driven to learn new domains quickly and choose the simplest effective architecture, tools and paradigms for each problem.

Also open to do custom software development!

Services: Healthcare data engineering, Clinical data pipelines, AI/ML integrations, Cloud architecture, Full-stack development, Technical Discovery

About Me: I'm Karan Krishnani, an independent software consultant with almost 20 years of experience. For the last several years I've been focused on healthcare tech, building HIPAA-compliant data pipelines, clinical analytics infrastructure, and AI applications for organizations like Tuva Health, NYU Langone, and VA.gov. I work best as a fractional embedded team member for healthtech companies that need senior technical help without a full-time hire.

Remote: Remote first, but I enjoy spending time with my collaborators (especially at the beginning of a mission) and traveling for work from time to time.

Willing to relocate: Temporarily, depending on the job but not for more than 6 months. Might be only available 2 days/week during the next months.

Technologies: Can learn anything web related very quickly but I'm especially proficient as a full stack working with a boring Python/Django/PostgreSQL stack. I enjoy working with Vue.js or Svelte but I will keep using HTMX or Alpine.js whenever I can out of simplicity. Happy to use low-code tools and vibe code stuff when it makes sense. I can also use Cloud solutions (GCP, Render, Heroku, AWS) or administrate a Linux server.

Python/Django specialist looking for projects bridging tech and physical world. Currently available for freelance work. I bring 5+ years building production software—from co-founding a legal tech startup where I wore every hat from Linux sysadmin to team lead, to a recent stint at Louis Vuitton on JS/TypeScript. Comfortable across the stack, with particular depth in data pipelines, ML/computer vision, and making things work reliably at scale. M.S. in Computer Science (computer vision) from Sorbonne, dual B.S. in Math & CS, plus a foundation year in applied arts. This mix shows up in my work—I care about both what's under the hood and what users actually see.

I'm quite good with people and enjoy being part of a team. Looking for interesting projects at the intersection of software and visual/creative domains, or anything hardware / real world related -- but honestly, I enjoy hard problems wherever they live.

Open to contracts, part-time collaborations, or interesting project-based work. Based in Paris, remote-friendly.

Don't hesitate to get in touch. ;-)

Regards.
