Yagasaki7K

software engineer & cyber security (wip) focused on reseach, pentest, scalable architectures & AI

specialist in process optimization – reducing execution times by up to 35% (Next.js/Go @ MeuBoi) and increasing conversions by 28% (Typescript/Python @ Astriia) through AI and payment integrations (Stripe/LiraPay).

I'm a programmer and cyber security too (wip), passionate about building robust high‑performance systems. my work spans modern web applications, distributed backends, API integrations, AI, and real‑time systems. I constantly seek to combine performance, best practices, and creative solutions to solve real‑world problems.

  • currently exploring Go Lang and Cybersecurity.
  • ask me about Node.js, Next.js, TypeScript, Prompt Engineer, and payment integrations.
  • I believe well‑written code is the best documentation.

Technologies

  • Languages: JavaScript, TypeScript, Python, Go
  • Frameworks: React, Next.js, Node.js, NestJS, Express, Fastify, Elysia.js
  • Databases & ORMs: Prisma, PostgreSQL, MySQL, Supabase, Firebase
  • Platforms & Tools: Docker, Vercel, GitHub Actions, Serverless, Google Cloud
  • Testing: Jest, Storybook, Node:test, Bun:test

Featured Projects

Project What I built
pb-sqlite Polarbear Database SQLite (pb-sqlite) is a browser SQLite for offline-first applications, with OPFS persistence, worker threading, React hooks, and safe multi-tab coordination.
PakeHub Pake Application Hub is a community catalog of desktop applications generated from web applications. The project packages useful websites as installable Windows, Linux, and macOS applications, so they can be opened from the desktop without keeping another browser tab pinned.
RDVNC2000 R-DVNC2000 is a Progressive Web App (PWA) that replaces your device's camera app with a fully simulated early-2000s digital camcorder. It captures your camera feed, runs it through a custom WebGL shader in real time, and records the processed result to a downloadable video file — all without a native app, a backend, or any server-side processing.
WakeOnLan A responsive React app that discovers devices through a local network relay and sends Wake-on-LAN packets. The browser and Android WebView cannot read ARP neighbors or send UDP broadcasts themselves, so the relay must run on a computer or always-on device connected to the same LAN.
Learn Taekwondo Learn Taekwondo is a Next.js web application that serves as a study guide for World Taekwondo (WTF) students.
Cerberus Cerberus is a screen-sharing MVP that works directly between browsers. It uses PeerJS Cloud only for signaling and WebRTC P2P for media; there is no database, authentication, history, custom API, or media server.
MeuBoi A complete livestock management platform organized as a monorepo, with a .NET backend, Next.js frontend, PostgreSQL integration, authentication, domain/application/infrastructure layers, financial flows, ETL tooling, API contracts and dedicated technical documentation.
Steamfolio A Steam-inspired developer profile system that consumes GitHub data, calculates profile statistics, displays achievements and badges, and integrates external RSS content into an interactive interface.
Essentials A web utility designed to centralize useful software, tools and applications when setting up or rebuilding a computer, turning scattered installation knowledge into a searchable interface.
Findyourpet A platform for reporting lost animals, finding pets, and connecting people for adoption. Built with Next.js, React, Firebase, maps, Styled Components and client-side interaction flows.
Bun performance tests A runtime experiment comparing Node.js, Bun and Deno through compilation and execution tests, including mathematical workloads and Next.js project generation tests.
Bun ping monitor A lightweight networking utility built with Bun for monitoring latency and packet loss.
website/portfolio My personal web platform, built as a continuously evolving playground for modern Next.js, React, Styled Components, animations, Markdown, RSS, SEO, PDF generation and other web technologies.
