I am Shreyas Mishra. My online name is NotY215, and I also go by Fliczo online.
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. It combines Python-inspired syntax with a statically typed language design, type inference, a growing standard library, editor tooling, and an integrated compiler/runtime architecture.
The active compiler path is VIB (Vayu Integration Backend), built into the Vayu project. Its current verified execution route is:
.vyu source
|
v
Vayu frontend
|
v
Integrator lowering
|
v
VIR
|
v
VIR verifier
|
v
VIR interpreter
|
v
Program output and exit status
The implemented VIR subset includes arithmetic, strings and string methods, functions, return values, recursion, and basic control flow. The optional .vye package writer, reader, run path, Integrator dispatch, and content-addressed cache are marked complete in the roadmap.
Native machine-code generation is still planned, not complete. The current roadmap also tracks remaining interpreter/VM baseline repairs, branch-target verification, collections, modules, broader language support, measurement, ONNX, and release/self-host milestones.

PPSX33 is a Windows x64 PlayStation 3 full-recompilation research project. It loads decrypted ELF input, lifts supported PPU code into generated C++, links the host runtime, and works toward reproducing the PS3 services and hardware behavior required by games.
- Windows GUI, project workflow and build orchestration are present, with remaining gaps.
- ELF loading and PPU lifting are partial. Translation coverage does not prove semantic correctness.
- PPU runtime/control flow, LV2/PRX/NID services, SPU/MFC/DMA and SPURS are partial.
- Vulkan 1.2 is the default host graphics path. Swapchain presentation and guest RGBA upload are implemented baselines.
- RSX/GCM FIFO processing and assist/boot cmdstream drawing are partial. Title-authored rendering and shader behavior remain incomplete.
- Audio, input, filesystem and save-data paths have partial implementations.
- General game bootability and playability are not established.
The current roadmap prioritizes trustworthy PPU translation, guest runtime behavior, FIFO GET/PUT correctness, SPU behavior and title-authored RSX rendering. Diagnostic assists and static lift reports must not be presented as proof of working gameplay.

PPSX33-Web is the canonical source for the PPSX33 website. It contains the homepage, About, Architecture, Wiki/Documentation, Roadmap, Updates, FAQ and Developer pages, along with shared CSS, JavaScript, TypeScript sources and site assets.
The website repository owns the page source and static assets. The host-side router is separate. The project website is a documentation and presentation layer; the PPSX33 repository remains the source of truth for implementation status.

AIFIAR (Artificial Intelligence Framework for Interpretation and Reasoning) is an early-stage, provider-aware framework for disciplined AI-assisted software engineering. Its TypeScript workflow modules cover requirement tracking, repository context, planning, model routing, task scheduling, patch proposals, approval boundaries, transaction journaling and verification. Python tooling provides repository scanning, safety checks, patch validation and bounded command workflows, with an optional Docker runner.
Provider adapters include OpenAI Chat Completions and Responses, xAI, Anthropic, Gemini, Qwen/Qwen Code, and explicitly configured local or self-hosted OpenAI-compatible endpoints. The project includes language/provider instruction packs and durable repository memory. It is not yet a complete autonomous coding agent: authenticated approval UI, native Windows race-resistant file operations, production-grade host isolation and several deployment validation gates remain incomplete.
Repository: NotY215/AIFIAR
A Windows-first game packaging and installation project for files the user legitimately owns.
The current foundation uses C++20, C17, the Windows SDK, native Win32 UI, CMake and MSVC. It is designed around a versioned .noty package format, manifest generation, chunked processing, a generated Setup application and installation verification. The native Windows foundation and build architecture are present, but the complete package/repack/install pipeline is still in development. Cryptography is not implemented, so the project does not claim to provide encryption or authenticated package security.
A lightweight Fabric client-side Minecraft mod that moves a Totem of Undying into the off-hand at a low health threshold and returns it to its original slot after recovery. It has a toggle keybind and separate builds for Minecraft 1.21.9–1.21.11 and 26.1.x–26.3, using the appropriate Yarn or Mojang mappings.
A lightweight Minecraft plugin with heart-based HP indicators and Vault integration for displaying player balances below the health bar.
DXFS is a C++17 digit-container file format and terminal editor. It supports packed decimal storage and generator-based representations such as repeating patterns and known constants. Its design distinguishes genuine compression from compact recipes that regenerate predictable digit sequences; arbitrary random digits remain bounded by their information content. The project provides dxtool for packing, unpacking, generation and validation, plus a POSIX full-screen editor.

Expand the verified VIB/VIR language subset, complete the remaining baseline repairs, and progress through verifier hardening, collections, modules and later native code generation milestones.
Continue PPU translation trust, guest runtime and HLE correctness, SPU/MFC/DMA behavior, and title-authored RSX/GCM rendering. Keep all compatibility claims tied to end-to-end evidence.
I learn by making things, breaking them, fixing them and trying again.
