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
// Interactive

Interactive Applications (PWA)

Tools that work like native apps. Emphasis on UX, State Machine architecture and instant response on every device.

Seamless UX Offline-first
// Intelligence

AI & Automation Scripts

Replacing manual work with intelligent algorithms. From data processing to complex real-time decision trees.

Voice Power

A polling system where vote weight is not equal for everyone — it dynamically changes based on the user's credibility and activity history. The algorithm rewards constructive contributors and naturally eliminates spam. Result: mathematically fair voting with high data integrity.

Reputation System Weighted vote power calculation based on historical activity and voting accuracy.
Lightning Performance Minimalist implementation focused on instant processing of thousands of votes.
  • Dynamic weighted-voting engine
  • Ultra-fast Symfony kernel
  • Anti-manipulation protection
Detailed technical solution

-- Reputation-weighted consensus: louder voice = more history

    ROUND(

    )            AS consensus_pct,
    COUNT(v.id)  AS total_votes
FROM polls p
JOIN votes v ON v.poll_id = p.id
JOIN users u ON u.id = v.user_id
WHERE p.closes_at > NOW()
  AND u.is_banned = 0
GROUP BY p.id, p.question
ORDER BY consensus_pct DESC;

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.
