Building from first principles.
I'm Zajfan—a software engineer focused on custom game engines, distributed cloud infrastructure, compilers, and enterprise software.
Latest Release
DevTrack 1.0
Projects, tasks, subtasks, notes, and time tracking in a single native app. Your data lives in one SQLite file on your machine: no server, no account, no telemetry. v1.0 ships for Windows, macOS, and Linux; iOS, Android, and HarmonyOS ports are in progress.
Pillars of Craft
Core Engineering Domains
Graphics & Engine Dev
Writing rendering engines in C++ and OpenGL. Specializing in greedy meshing algorithms, chunk streaming, shader pipelines, and custom physics simulation.
Distributed Systems & Cloud
Architecting the Nexus Systems platform. Distributed service registries, cryptographic vault rotation, edge reverse proxies, and automated deployment pipelines.
Compilers & Enterprise Solutions
Engineering from high-throughput enterprise systems (Södervidinge Bakery .NET ERP) to massive language compilers (Nexuslang AST & 210K+ LOC toolchain).
Selected Works
Featured Engineering Projects
Nexus-Cloud
Distributed multi-node control plane, service registry & DNS engine
The architectural backbone of the Nexus Systems cloud ecosystem. Features an event bus, dynamic service registry, federated node discovery, deployment API, DNS routing, policy placement, and multi-tenant quota scheduling.
Nexus-Vault
Cryptographic secret storage, key rotation & zero-trust authentication
High-security secrets and key management service for microservice clusters. Implements automated key rotation, periodic cryptographic verification, encrypted automated backups, mail verification, and fine-grained rate limiting.
Nexus-Hosting
Self-hosted edge proxy, container router & application hosting service
Containerized hosting and reverse proxy platform designed to run production workloads, web applications, and APIs with automated SSL, subdomain routing, and load balancing.
Nexus-Database
Custom embedded B-Tree storage engine with Write-Ahead Logging (WAL)
Low-level embedded database engine built in C++. Implements custom memory paging, B-Tree indexing, write-ahead logging (WAL) for durability, and crash recovery.
Versa Game Engine
Modular 2D/3D game engine with custom rendering and entity-component architecture
A modular, high-performance C++ game engine featuring OpenGL/Vulkan rendering abstraction, an entity-component-system (ECS) architecture, scene graphs, and asset pipelines.
Voxel Engine 2
Real-time voxel world generator with greedy meshing & chunk streaming
High-performance C++ voxel engine featuring 3D Perlin/Simplex procedural terrain generation, chunk streaming, greedy meshing to reduce draw calls, and dynamic lighting.
Development Diary
Recent Engineering Notes
DevTrack 1.0 Is Out: Local-First Project Management for Solo Developers
DevTrack reaches v1.0 on Windows, macOS, and Linux. One native app for projects, tasks, notes, and time tracking, with Git and GitHub awareness built in and your data kept in a single SQLite file.
Architecting Nexus-Cloud: Zero-Dependency Distributed Control Plane
How we built the control plane backbone for Nexus Systems: service registry, heartbeat reconciliation, federated DNS, and multi-tenant quota scheduling in TypeScript.
The Nexus Systems Platform
Most of my systems work goes into Nexus Systems, a free, self-hostable cloud platform from The No Hands Company, built on Nexus-Hosting, Nexus-Cloud, and Nexus-Deploy.
