Advanced Frontend Engineering & Performance Optimization.

While frameworks change, the core remains. I possess deep knowledge of raw HTML/JS/CSS, allowing me to solve complex issues that framework-only developers cannot fix.

My Engineering Standards:

- Modern JavaScript (ES6+ / TypeScript): Writing strictly typed, bug-free logic. No "spaghetti code."

- Semantic HTML5: Structuring code specifically for SEO and Accessibility (a11y). Google ranks my sites higher because robots understand them better.

- Advanced CSS: Mastery of Tailwind CSS, SCSS, and modern layout techniques (Grid/Flexbox). I ensure Pixel-Perfect implementation across all browsers (Chrome, Safari, Firefox).

- Performance: Optimization of Core Web Vitals (LCP, CLS). I know how to minimize reflows and repaints for 60fps animations.

I build the solid foundation upon which your application runs.

Modern PHP Development (Laravel / Symfony).

PHP powers 70% of the web, but quality matters. My backend partner specializes in Modern Enterprise PHP, building secure and fast applications.

Our PHP Expertise:

- Frameworks: Laravel & Symfony ecosystem. We write clean, object-oriented code (OOP).

- API Development: Building robust RESTful / GraphQL APIs to feed data to my React/Next.js frontends.

- Speed: Optimization for high traffic (Redis caching, database tuning).

- Legacy Refactoring: We can take an old PHP project and migrate it to a modern architecture.

Stable, proven, and cost-effective solutions for business logic.

Business Automation, Scraping & Bots (Python/Node.js).

We write scripts to automate boring tasks and save you money.

What we automate:

- Telegram Bots: Advanced bots for sales, support, and community management (our specialty).

- Data Scraping: Parsers to monitor competitor prices or gather leads from the web.

- API Integrations: connecting different services (e.g., CRM <-> Google Sheets <-> Website) to work as one ecosystem.

- Data Processing: Python scripts for analyzing and formatting large datasets.

If you are doing something manually more than once a day — we can script it.

Technical Consulting, Code Audits & CTO Services.

Sometimes you don't need code yet; you need a plan. Or you have a buggy project and need to know why.

I offer High-Level Engineering Services:

1. Code Audit: I will review your current project (React/Python/PHP), find security holes, and tell you why it's slow.

2. Architecture Planning: Designing the database schema and technology stack BEFORE you start spending money on development.

3. Telegram Mini Apps Strategy: Consulting on how to launch your business inside Telegram.

4. Rescue Missions: Fixing critical bugs in abandoned projects.

I provide clarity and technical leadership for your business.

Advanced Python Backend: Django, FastAPI & AI.

For projects requiring heavy calculation, AI integration, or extreme speed, I deploy my Senior Python Partner.

What we build with Python:

- High-Load Backends: Using FastAPI (asynchronous) for real-time applications and Django for secure enterprise systems.

- AI & Data: Integration of OpenAI (GPT) APIs, data scraping, and processing pipelines.

- Telegram Ecosystems: Complex backends for Telegram Mini Apps and Bots.

- Microservices: Scalable architecture using Docker/Kubernetes.

The best choice for Startups, Fintech, and Data-driven projects.

Enterprise-Grade Backend Architecture (Python/Django).

This is the core strength of my partner. We build secure, scalable backends for complex platforms where security and data integrity are paramount.

Our Django Stack:

- Security: Banking-grade security features (ideal for Fintech & Crypto projects).

- Admin Panels: Customizing Django Admin for efficient business management.

- Scalability: Dockerized environments ready for AWS/Google Cloud.

Perfect for Startups, SaaS, and marketplaces that need a solid foundation.

Enterprise Angular Development & Migration Services.

While I personally specialize in React, my in-house partner is a Senior Angular Developer. This allows us to handle heavy Enterprise legacy codebases.

Our Services:

- Maintenance: Support and bug fixing for existing Angular applications (v2+ to v17).

- Migration Strategy: Safely rewriting old AngularJS/Angular apps to modern React/Next.js architecture without breaking business logic.

- Hybrid Apps: Integrating modern components into legacy systems.

Ideal for Enterprise clients (Banks, Insurance, Gov) looking for reliable support.

Legacy Code Modernization & Migration to React.

I don't build new projects on jQuery Mobile (it's obsolete). Instead, I specialize in Rescuing Legacy Projects.

My Service:

- Migration: I safely refactor old, slow jQuery codebases into modern, fast React/Next.js applications.

- Bug Fixing: If you have an existing system that needs maintenance, I can read and fix "spaghetti code" that others refuse to touch.

- Performance Boost: Upgrading from jQuery Mobile to modern frameworks typically increases speed by 300%.

Don't let your business run on 2012 technology. Let's upgrade it.

End-to-End Product Development (React + Python / PHP).

I provide a complete software production cycle. Unlike solo freelancers who get stuck on complex tasks, I lead a specialized unit that delivers fully integrated products.

Our "Right Tool for the Job" Approach:
I handle the Frontend (React/Next.js), while my backend partners handle the server logic based on your needs:

- Option A: Python (Django/FastAPI): Best for High-Load SaaS, AI integrations, and heavy data processing.

- Option B: PHP (Laravel/Symfony): Best for classic Web Applications, CRM systems, and fast-to-market MVPs.

Why hire this setup?

1. Versatility: We don't force one language. We use what's best for YOUR business.

2. Unified Responsibility: I am your single point of contact. I manage the architecture and ensure the Frontend and Backend communicate perfectly.

3. Scalability: From simple admin panels to complex microservices - we cover it all.

Senior React.js & Next.js Architecture (High-Performance).

I specialize in building large-scale, complex Single Page Applications (SPA) where performance matters.

My Production Stack:

- Next.js (App Router): For perfect SEO, SSR, and lightning-fast initial load.

- State Management: Redux Toolkit / Zustand / Context API — tailored to the project's complexity.

- Code Quality: TypeScript for type safety, ESLint/Prettier for clean code, and strict Component composition patterns.

- Optimization: Solving re-render issues, code splitting, and optimizing Core Web Vitals.

I write clean, reusable, and self-documenting code that is easy to maintain.

You get a Figma file that is 100% ready for pixel-perfect React/Next.js development

Professional UI/UX Design & Prototyping (Integrated Workflow).

I am a Developer who understands the value of great design. That's why I don't rely on generic templates.
