Technology Arsenal

// 01

Symfony Core

8+ years, 30+ enterprise projects. Specialisation in robust backend architectures, high performance and security.

Symfony 8 PHP 8.5 DDD PostgreSQL
// 02

AI Integration

LLM integrations (GPT-4, Claude), RAG systems for corporate data and autonomous agents. AI as a tool for efficiency, not a buzzword.

OpenAI API RAG Python Vector DB
// 03

PWA & State Machines

Blazing-fast frontends with instant response. Offline-first approach and absolute control over application state.

Stimulus Turbo Service Workers XState
// 04

Infrastructure

Modern deployment and scaling. Containerization, CI/CD pipelines and real-time system monitoring.

Docker CI/CD Linux Admin Nginx

Engineering Pillars

Solutions designed for scalability, performance and long-term maintainability.

// Architecture

Robust Backend Systems

Focus on performance, multithreading on Linux/Windows, secure APIs and complex relational structures. Symfony as the core of your business.

High Performance Enterprise

Paper Mysteries

A mobile text RPG paying homage to 80s classics, but under the hood with a full Symfony stack, HTML5 Canvas renderer, and asynchronous Messenger. My personal showcase — 13 years of architectural experience without a single compromise. Old school, lightning performance, modern PWA.

Component Dominance Highly reusable component system for rapid expansion of game content.
Modern Retro Interpretation Combining 80s aesthetics with the lightning-fast responsiveness of modern web technologies.
  • Stimulus.js with custom Canvas rendering
  • Modular Game Framework
  • Full Symfony/Messenger integration
Detailed technical solution
game_controller.js
// Stimulus + Canvas — retro RPG in the browser
import { Controller } from '@hotwired/stimulus';

export default class extends Controller {
  static targets = ['canvas', 'dialogue'];

  connect() {
    this.ctx = this.canvasTarget.getContext('2d');
    this.#loadScene(this.element.dataset.sceneId);
  }

  async #loadScene(id) {
    const scene = await fetch(`/api/scene/${id}`)
      .then(r => r.json());
    this.#renderMap(scene.tiles);
    this.dialogueTarget.innerHTML = scene.text;
  }

  #renderMap(tiles) {
    tiles.forEach(({ x, y, sprite }) =>
      this.ctx.drawImage(this.sprites[sprite], x * 32, y * 32)
    );
  }

Architectural Process

01

System Analysis

Deconstruction of the problem into elementary parts. Identification of bottlenecks and definition of uncompromising goals.

Status: Analyzing dependencies...
02

Proof of Concept

Rapid validation of critical algorithms and integration points. Elimination of technological risks at an early stage.

Logic: Validating O(n) complexity...
03

Architecture Blueprint

Design of a robust system with regard to scalability, security and future AI automation.

Stack: Symfony Core + Vector DB
04

Core Engineering

Writing highly efficient code, implementing business logic and ensuring 100% test coverage.

Git: feat(core): implemented async drivers
05

AI & Fine-Tuning

Integration of LLM models and prompt tuning for specific company data. Increasing process efficiency.

AI: RAG engine optimization active
06

Enterprise Ops

Production deployment, real-time monitoring and continuous performance optimisation under load.
