Web development
Development of websites, web applications and online stores.
From idea to a stable production launch
I build web products that solve business problems
I handle website, API and integration development as well as the server environment. The process is transparent: a clear area of responsibility, a verifiable result and support after launch.
01
Services
What I do
Infrastructure
Hosting, domains, SSL certificates and server environments.
Bots
Bots for Telegram, WhatsApp, Instagram, Facebook and other messengers except Viber.
API
API and REST API design, development and integration.
Integrations
Payment systems, CRM, warehouses, delivery services and other external platforms.
Technical SEO
Technical SEO corrections based on a specification prepared by an SEO specialist.
02
Business outcomes
What your business receives
Not a list of frameworks and server panels, but a concrete result that can be launched, verified and used in daily work.
A finished product, not a folder of files
I can take a project from task clarification to launch: build the website, store or internal service, configure the environment, move it to your server and verify it after migration.
Result
A solution that can be used immediately after acceptance.
Less manual work
I connect the website to CRM, payments, delivery, inventory, billing and other services so data is transferred automatically instead of being copied between dashboards and spreadsheets.
Result
Faster operations and fewer human errors.
Functionality built around your process
Customer accounts, booking, staff roles, catalogues, filters, imports, queues and other features that are missing from standard themes and plugins.
Result
The website adapts to the business, not the other way around.
Control and understandable data
I build APIs, internal panels, audit services and analytics dashboards that collect the required indicators in one place and present them in a useful format.
Result
Less time spent searching and faster management decisions.
A stable operating environment
I select and configure hosting or a server, domain, SSL, web server, mail delivery, background jobs and deployment without requiring a different administrator for every step.
Result
The project does not merely launch — it keeps working reliably.
Help with an existing or problematic site
I diagnose legacy code, find the cause of errors, recover sites after infection, migrate projects and add features without automatically rewriting everything from scratch.
Result
The working business process is preserved and risks remain controlled.
In short
If your task goes beyond simply installing a theme, this is where my combined development and infrastructure experience brings the most value.

Hands-on experience
Problems I have already solved
For a client, job titles matter less than whether the developer has already faced a similar problem and can own the relevant part of the solution.
An online store as one process
- Task
- Unify catalogue, orders, payments, delivery and manager workflows.
- What I did
- Built stores, customer accounts and integrations with CRM, payment systems, delivery services and product synchronisation.
- Value
- Orders follow a consistent path and the team spends less time moving data manually.
Data exchange between different systems
- Task
- Allow the website, mobile application, CRM, billing and corporate services to work with consistent data.
- What I did
- Designed REST APIs and integrations with CRM, LDAP, billing, logistics and other third-party services.
- Value
- Less duplication, fewer mismatches and a clear integration point between systems.
Dashboards instead of manual checks
- Task
- Collect audit and analytics data in one place and provide controlled access.
- What I did
- Designed and maintained internal audit services and analytics dashboards on Laravel and Yii2 Advanced.
- Value
- The team sees the required system state without searching across sources or compiling reports manually.
Changes without stopping an operating business
- Task
- Support an outdated project and fix errors or vulnerabilities when a complete rewrite is not immediately possible.
- What I did
- Worked with legacy code across multiple CMS platforms, cleaned infected servers, closed vulnerabilities and migrated projects.
- Value
- The site keeps running while critical issues are resolved through controlled changes.
Mailings and tasks without blocking the site
- Task
- Send email and push notifications and run synchronisations or long operations without blocking the user.
- What I did
- Configured queues, mail servers, sender reputation, background jobs and deliverability monitoring.
- Value
- The interface stays responsive while heavy tasks run in a controlled and repeatable way.
Thousands of pages without overloading the server
- Task
- Create pages from large hierarchical datasets while preserving structure.
- What I did
- Built a WordPress plugin that processed 5,000+ parent records per run using chunks, the Transients API and resource control.
- Value
- Mass content generation becomes automated instead of requiring thousands of pages to be created manually.
