Achachi Software designs, builds, and maintains custom software — from backend services and desktop apps to DevOps automation and bots — across Java, C#, Python, and JavaScript, adapting to whatever a project calls for.
Achachi Software takes on contract and freelance work — from one-off builds to ongoing feature work and maintenance. Core areas of focus:
Windows and cross-platform desktop tools in Java/JavaFX and C#/.NET — utilities, launchers, and internal tooling.
GitHub Actions pipelines, build and release automation, and integrations that take the manual steps out of a workflow.
Discord bots, scheduled jobs, and data-tracking tools that automate the tedious parts of running a product or community.
Node.js services, REST APIs, licensing and provisioning systems, and the server infrastructure that ties them together.

A suite of premium and free automation plugins for the Storm OSRS client. Covers NMZ, Construction, Prayer training, Fishing, Thieving, Smithing, PvP utilities, and more. Ships with a shared utility library (AchachiUtils) providing overlays, delay randomisation, and XP failsafes.
A Node.js backend that manages the full plugin distribution lifecycle — license checks, pricing commands, version updates, user provisioning, and audit logging. Integrates with Discord for operator commands and exposes a REST API consumed by the Storm client loader.
A Windows kernel-mode driver implementing stealth code and data areas, IOCTL command dispatching, and low-level I/O request handling via the NT kernel API. Designed to operate below user-mode visibility for research into kernel-level privilege and memory control.
A reverse-engineering study of the CS:GO client, built as an injected internal C++ module. Maps the Source Engine's client and engine interfaces through inline hooking, runtime memory analysis, animation-state inspection, and DirectX overlay rendering.
C# DLL injector supporting LoadLibrary, Manual Mapping, and Thread Hijacking. Includes DLL ejection and config persistence.
GitHub →DLL injector with a pluggable injection method interface — supports Manual Mapping, LoadLibrary, and Thread Hijacking with header erasure.
Material Design DLL loader UI for selecting target processes and injecting modules. Uses P/Invoke for Windows API calls.
GitHub →Client-server remote DLL injection tool allowing injection into processes on remote machines over a network connection.
External tooling that reads CS:GO game state from process memory — entity enumeration, world-to-screen math, and offset management. A study in non-intrusive runtime memory analysis.
GitHub →A Direct3D hooking experiment that intercepts the present chain via IAT patching from an injected DLL, used to analyze and overlay rendered frame data.
GitHub →Discord bot managing role-based plugin subscriptions — handles expiry, automatic role assignment/removal, and owner commands via cog architecture.
A Python tool that fetches player match history from the OP.GG API and feeds statistical patterns into OpenAI to identify potential account boosting indicators — unusual win rates, champion pools, and performance spikes.
Achachi Software is a software studio offering contract and freelance development alongside its own suite of products. It operates as a sole proprietorship.
The focus is on practical tools and utilities — software that solves real problems or automates tedious workflows — spanning desktop apps, backend services, system-level tooling, and bot development, with the right language or framework chosen to fit each job. Much of the public work lives in the OSRS ecosystem, including a full plugin suite for the Storm client and the infrastructure behind it.
