How we work

Honesty

An honest approach to the result. We start with a detailed audit - code, security and functionality. Based on this, we set transparent goals and determine realistic deadlines. We take on a project only when we are 100% sure of success.

Flexurability

Communication built around you. We work in your rhythm and stay in touch at any time convenient for you. A personal manager is assigned to your project, who will promptly answer any question and solve any task. Our goal is to provide you with full control and transparency at all stages of development.

Permanent reporting

We regularly report on our work and the results achieved. Twice a week, we send a brief status update, and once a month, we provide a comprehensive report detailing completed tasks, planned improvements, and projected timelines.

We talk about the most common pains and problems of our clients

Usually, you will see the first results within the first month after implementation. We carefully plan and prioritize tasks so that key improvements start working as quickly as possible — whether it’s faster loading speed, increased conversion rates, or optimized business processes.

Yes. Before starting any work, we conduct a detailed audit and only take on projects when we are 100% confident in success. Quality is checked at every stage, and the final solution is tested for functionality, security, and performance.

The cost includes the full development cycle: audit, UX/UI design, backend and frontend development, service integration, testing, optimization, security setup, as well as post-project support and consulting.

We use proven and modern technologies: from popular frameworks (React, Vue, Laravel) and CMS (WordPress) to cloud platforms and DevOps tools. The technology stack is selected based on the project’s goals and scale to ensure the best balance of speed, reliability, and security.

Implementation is carried out by our team of specialists: developers, UX/UI designers, testers, security experts, and a project manager. Each stage is handled by professionals in their field, and the client is always kept informed of progress.

Clients about us

We, the Olcha team, would like to express our sincere gratitude to the Celion team for their attention to detail and professionalism in identifying and fixing the ulnerabilities of our website. Their ability to identify complex security issues and offer effective solutions has helped us significantly improve the security of our data and services. Their work has undoubtedly played a key role in protecting the interests of our clients and strengthening trust in our brand.

Top Brains would like to express its sincere gratitude to the Celion team for their expert analysis and professional intervention in improving our cybersecurity. The work they have done, including identifying and fixing complex vulnerabilities, has significantly HELPED us to secure our customers' confidential information and improve the overall security level of our systems. This contribution is of great importance to our business, and we highly value their professionalism and dedication to their work.

Working with "Celion" has been a great satisfaction for us. They have carried out a comprehensive analysis of our systems and implemented effective security measures that meet the highest standards. Particularly noteworthy is their individual approach to our needs and their quick response to any emerging threats.

The employees of "Celion" demonstrated a high level of professionalism and competence. Their approach to implementing solutions was carefully thought out and adapted to our specific needs, which allowed us to minimize risks and strengthen our information security. The team was always in touch and promptly responded to any questions that arose. We are confident that "Celion" will continue to provide high-quality services to its customers and recommend them to anyone who needs reliable and professional support in the field of cybersecurity.

Celion served as an external sanity check on our stack: a layered audit that cataloged vulnerabilities, control gaps, and policy misalignments. The remediation roadmap they delivered let us harden data protections in a disciplined way and bring our processes into line with industry standards. Their post‑audit follow‑through was excellent—fast responses and hands‑on guidance through implementation. They’re a partner we trust on high‑criticality initiatives.

Celion ran a full audit of our systems, rapidly surfacing vulnerabilities and control gaps. Their clear remediation roadmap let us harden data protection and bring our processes into line with industry standards fast. For critical projects, Celion is a partner we can count on.

Within weeks of working with Celion, we strengthened data protection at Express 24 and brought our processes up to industry standards. That progress came from their rapid, comprehensive security audit, which surfaced critical vulnerabilities and clear, practical fixes. Celion responds quickly—they're a partner we trust.

With the user‑friendly app and interactive Power BI dashboard (complete with custom visuals) that Celion built for IHMA, we track key metrics in real time and make faster, data‑driven decisions. The build quality and attention to detail stood out. Celion is a partner whose work delivers tangible value.

Since rolling out the Celion‑built APK app, PraeLegal has significantly sped up document handling and reduced manual effort. The app centralizes fast info lookup, document list management, and automated routines, while One ID single sign‑on keeps staff access secure and seamless. Working with Celion is driving real efficiency gains.

Since rolling out the unified mobile app and admin console Celion built for EMU University, the academic process is more transparent and engagement is stronger. Parents can track grades, schedules, attendance, and complaints in one place, while faculty and admins manage data and roles through an intuitive dashboard. Built‑in notifications ensure no one misses grade updates, schedule changes, or attendance issues. The solution brings students, teachers, and parents together in a single system.

Analysis of commercial ranking factors

Preliminary analysis

We begin by studying the current state of the project - whether it's a website, mobile application, or integrated system. We define the main business goals, analyze functionality, design, user experience, and identify strengths and weaknesses.

How we analyze:

We collect information about current architecture, technologies used, and integration;
We check performance (speed, load) and overall solution stability;
We fix the main problems that interfere with development or pose a security risk.

Technical Audit

We thoroughly examine the technical aspects to identify errors, vulnerabilities, and bottlenecks that affect stability and scalability.

How we conduct the audit:

We check code quality, dependencies, and environment configurations;
We assess security: access management, encryption, vulnerabilities, and backups;
We test compatibility with standards, browsers, devices, and API integrations.

Structure

We analyze the logic and hierarchy of content so that users can quickly find what they need and not get lost in navigation.

How we conduct structure analysis:

We map user journeys and usage scenarios;
We check navigation, internal linking, and clarity of section names;
We identify duplicates, unnecessary steps, and points where conversion drops.

Optimization

We enhance the speed, stability, and visibility of your resource for users and search engines without compromising quality.

How we conduct optimization:

Internal optimization: code cleaning and decomposition, image optimization, caching, meta tags;
External optimization: proper redirects, sitemap, schema markup, technical signals;
Improvement of Core Web Vitals, responsiveness, and accessibility (a11y) of interfaces.

Commercial factors

We enhance elements of trust and convenience that influence the conversion rate and commercial effectiveness of the project.

How we evaluate commercial factors:

We check forms, shopping cart, payment options, communication methods, and transparency of terms;
We optimize the path to purchase: fewer clicks, more prompts, and clear calls-to-action;
We add/verify social proof: ratings, reviews, certificates, and guarantees.
