Jitu Das
Systems Engineer & Unikernel Architect
I build bare-metal systems, custom hypervisors, and zero-overhead runtimes. This entire website is compiled into a single-address-space binary and served directly by a custom Rust webserver running on a virtualized hypervisor.
About Me
I focus on stripping away abstraction layers to build software that talks directly to the hardware. By replacing general-purpose operating systems with single-purpose unikernels, I aim to achieve the maximum possible security, execution speed, and predictability for cloud services.
My work spans early Assembly bootloaders, custom paging configurations, lock-free queue drivers, and from-scratch protocol implementations (like TCP/IP, TLS 1.3, and QUIC/HTTP/3). I believe the best way to understand a system is to build it from the raw interrupt vectors up.
Projects
Rust Unikernel
A bootable, single-binary operating system substrate. Includes early paging tables, per-CPU initialization, cooperative multi-core scheduling, and native VirtIO/gVNIC network card drivers.
Custom TCP/IP & TLS Webserver
A high-performance webserver executing in the unikernel. Implements a from-scratch TCP stack with O(1) flow lookups, zero-copy buffer transfers, and a hand-rolled TLS 1.3 handshake using audited cryptographic primitives.
Bzlmod Monorepo & Deployment
A robust Bzlmod setup compiling bare-metal targets and native runtimes under a single dependency graph. Automated GCE image deployment pipelines with UEFI/BIOS multi-boot integration.
