Engineering Lead and Systems Architect working across fintech, health-tech, and open source.
I've led teams to build the bKash Business platform for 200,000+ merchants, co-founded an open-source ERP used by 300+ retailers, and architected HIPAA-compliant healthcare systems.
On the side, I tinker with FOSS projects like nkrypt.xyz, libre.money, and tiny JavaScript games for js13kGames.
- Trying to make things safer with nkrypt.xyz
- Giving a proper shot at FOSS money management with libre.money
- Obsessing over medieval German and Anglo-Saxon history (lately: the Teutonic Order)
If you are here on official business, I do have a proper portfolio website at sayemshafayet.com
Additionally, if you need an extra pair of experienced hands for a Free and Open Source project with a good cause, I am willing to help pro bono.
