I am Shreyas Mishra, also known as NotY215.

I am an independent developer working on programming languages, compilers, systems, AI, media, games and developer tools.

I like going below the surface. If something is interesting, I want to understand how it works and eventually build my own version.

Vayu is my main programming-language project.

The direction is a Python-inspired language with native compilation, static typing and type inference, low-level control, C/C++ interoperability, tooling, packages, GUI and application development, games, graphics and future AI/ML support.

VCB means Vayu Compiler Backend.

It is a separate C++20 backend project focused on taking Vayu toward direct native code generation.

Current areas include:

• Textual SSA IR
• IR parser and printer
• vcb dump
• x86-64 code generation
• PE and ELF writers
• Runtime integration

VCB is developed independently so the backend can evolve without being tied to the rest of the compiler.

NotYVOS is an x86-64 operating-system project.

The project works with:

• C
• C++
• x86-64 Assembly
• Clang/LLVM
• CMake
• Ninja
• Limine

It also explores a PS3-compatible execution environment as part of the wider systems work.

Upscaler: Repository
Caption Official: Repository

A Windows game packaging and repacking system built around a custom .noty package format.

Stack: C++20, Qt6, CMake, Zstandard, AES-256-GCM, BLAKE3, streaming and multithreading.

Repository

A Fabric client-side Minecraft mod for automatic Totem of Undying management.

DXFS is a C++17 file-format and terminal-editor experiment focused on compact representations of large digit sequences using packed data and generators.

Languages: C++ • C • Python • Java • Vayu • x86-64 Assembly
Systems: CMake • Ninja • LLVM • Clang • Git
AI & Media: Whisper • Spleeter • FFmpeg • Nuitka • PyInstaller
Application & Game: Qt • Fabric • Minecraft • OpenGL • Windows

Compiler, runtime, standard library, packages, LSP, formatter, linter, debugging, GUI, graphics, game development, AI/ML and native interoperability.

Turn VCB into a capable native backend with its own IR, code generation, object writers and runtime path.

Compilers, IRs, code generation, linkers, operating systems, runtimes, file formats, networking, graphics and CPU architecture.

Not every project needs to become huge. Small experiments are part of learning too.

I also spend time on:

• 🎬 Video editing
• 🎞️ Anime edits
• 🖼️ Visual design
• 🎮 Gaming
• 🧩 Game development
• 🧪 Technical experimentation

Creative work and programming often overlap in the same projects.

I learn by building.

The bigger direction is an ecosystem where the pieces connect:

Vayu is the center of that direction. The other projects let me explore different layers of software engineering.
