// SYSTEMS & WEB ARCHITECTURE

Luka Pajkanovic

Systems & Web Developer

I build high-performance software, systems-level logic, scalable web architectures, and interactive game mechanics from scratch. Focused on deterministic engineering, clean memory models, zero-overhead abstractions, and tactile digital interfaces.

[02]ENGINEERING PRINCIPLES & SYSTEMS DISCIPLINE

Building software with intention, deterministic logic, and precision.

As a systems and web developer, I favor clean memory models, compile-time type safety, and architectures that feel instant and unyielding under heavy load. From native engines to async web pipelines, the discipline stays the same: measure first, abstract only what earns its cost.

02 //Linear arena memory allocation preventing fragmentation
03 //Sub-100ms interaction feedback across web surfaces
04 //Zero-dependency core logic where latency is critical

Systems & Memory Models

C++20 / SIMD

Data-oriented architectures designed around CPU cache lines, deterministic fixed-timestep simulation loops, and custom contiguous memory arenas preventing heap churn.

Web Architecture

Strict type contracts, Next.js standalone container runtimes, and sub-100ms response cycles.
