Pleniko team
Plamen Nikolov
Owner & Managing Director | Senior Full-Stack Web Developer & Software Architect
As the owner and managing director of Pleniko Ltd., I have more than 20 years of professional experience in web development, software architecture, and digital infrastructure. Over the years, I have participated in the design and development of personal and corporate websites, complex web platforms, and complete systems for business management and process automation.
My primary focus is the creation of reliable, secure, and scalable digital solutions that address the actual requirements of each business. I believe technologies should be selected according to the project's objectives, expected workload, budget, security requirements, and potential for future development—not simply because they are currently popular.
At Pleniko Ltd., we work with a broad range of modern frontend technologies, most commonly using React, Next.js with Server-Side Rendering, Angular, JavaScript, TypeScript, Tailwind CSS, and Bootstrap.
The choice between an SPA, SSR, traditional server-side rendering, or a hybrid architecture depends on the project's requirements for performance, SEO, interactivity, security, and long-term maintainability.
When developing user interfaces, we place particular emphasis on:
For backend development, we primarily use PHP and Python. Our PHP projects are commonly based on Symfony and Laravel. When a project requires an established content management system, we also use WordPress, including custom development, integrations, and optimisation.
We have experience in the architecture and development of:
Depending on the structure, purpose, and expected workload of the project, we use MySQL, PostgreSQL, MongoDB, and Microsoft SQL Server.
When required, the architecture may also include Redis, object and S3-compatible storage, caching, background queues, and systems designed to process large volumes of information.
We place particular emphasis on data integrity, access control, isolation between different organisations and users, protection of sensitive information, recovery in the event of an incident, and the implementation of a reliable backup policy.
Server and Cloud Architecture
I have extensive practical experience with Linux, Windows Server, Unix-based systems, VPS and dedicated infrastructure, cloud services, and Microsoft Azure.
At Pleniko Ltd., we design, configure, automate, and maintain development, testing, staging, and production environments.
Our expertise in this area includes:
Personal and standard corporate websites may use reliable shared hosting when this is the more practical and cost-effective solution.
The final infrastructure is always selected individually according to the project's purpose, expected workload, required security level, and long-term development plans.
Design Implementation and Performance Optimisation
For visual development, we work with both custom concepts and professional design ideas and templates, adapting them to the identity, content, and functionality of each project.
Over the years, I have developed extensive practical experience in slicing, restructuring, and building complete designs using HTML, CSS, SCSS/SASS, JavaScript, Tailwind CSS, Bootstrap, Webpack, and modern asset pipelines.
Our work extends beyond visual implementation. It also includes optimising source code, images, fonts, and frontend resources so that the final product is fast, responsive, accessible, easy to use, and search-engine friendly.
Artificial Intelligence and Intelligent Automation
At Pleniko Ltd., we have been actively using Artificial Intelligence for more than three years as part of both our daily operations and the solutions we develop for businesses.
AI supports data analysis, software development and verification, issue detection, system monitoring, content processing, and the automation of repetitive processes.
We use AI for:
Our approach combines AI automation with human oversight, clearly defined access controls, and result verification—particularly when a system processes sensitive or business-critical information.
We use Artificial Intelligence as a tool that supports expert work, not as a replacement for human judgement in important decisions.
Security, GDPR, and Information Protection
Security is one of our highest priorities and a fundamental part of the architecture of every project we develop. It is not added later as a separate feature. Security is considered from the earliest stages of analysis, architecture, technology selection, and implementation.
In our development process, we apply the principles of Security by Design, Privacy by Design, and Privacy by Default. Whenever personal data is processed, we design the system in accordance with the applicable requirements of the General Data Protection Regulation—GDPR.
Depending on the purpose and risk profile of the project, we implement:
For us, GDPR compliance is not limited to publishing a privacy policy. It is part of how we design databases, user permissions, forms, administration panels, data retention periods, backups, and integrations with external services.
Reliability and Long-Term Support
Every project is developed with future maintenance, updates, security, and expansion in mind. We use technologies with proven stability and a clear long-term perspective while continuously following developments in modern web standards, UI/UX design, infrastructure, automation, cybersecurity, and Artificial Intelligence.
Pleniko Ltd. does more than build websites. Our objective is to create sustainable and secure digital products that protect information, simplify daily operations, automate real business processes, and continue to develop alongside the organisations that use them.
My primary focus is the creation of reliable, secure, and scalable digital solutions that address the actual requirements of each business. I believe technologies should be selected according to the project's objectives, expected workload, budget, security requirements, and potential for future development—not simply because they are currently popular.
Every business has different processes, objectives, and limitations. At Pleniko Ltd., we do not apply the same approach to every client. Instead, we design the technology and architecture around the individual requirements of each project.Web Development and User Interfaces
At Pleniko Ltd., we work with a broad range of modern frontend technologies, most commonly using React, Next.js with Server-Side Rendering, Angular, JavaScript, TypeScript, Tailwind CSS, and Bootstrap.
The choice between an SPA, SSR, traditional server-side rendering, or a hybrid architecture depends on the project's requirements for performance, SEO, interactivity, security, and long-term maintainability.
