5(1 review)Expert PHP Laravel & Symfony Applications Modernization, Refactoring and Optimization
cKlicky.com is a software engineering and web application optimization company specializing in refactoring, modernizing, and scaling PHP-based systems built with frameworks such as Laravel and Symfony. We help startups, SMEs, and growing digital businesses transform legacy or inefficient codebases into high-performance, secure, and maintainable applications. Our core focus is not rewriting software from scratch, but improving what already exists—preserving valuable business logic while eliminating technical debt and unlocking new levels of performance, scalability, and reliability. We provide end-to-end technical expertise across: • Code refactoring and modernization of legacy applications • Performance optimization (database queries, backend logic, and API efficiency) • Security audits and vulnerability remediation (SQL injection, XSS, CSRF, and more) • Technical debt reduction and long-term maintainability improvements • API refactoring, integration, and system architecture improvements • Backend and frontend optimization for speed, stability, and scalability We believe refactoring is often the smartest path forward—faster, more cost-efficient, and lower risk than rebuilding from scratch. Our work focuses on improving system architecture incrementally while ensuring business continuity and minimizing disruption. By combining deep expertise in PHP ecosystems with modern engineering practices, we help organizations extend the life of their applications and prepare them for future growth. Why clients work with us: • Improved application performance and response times • Reduced infrastructure and maintenance costs • Stronger application security and compliance readiness • Faster delivery of new features through cleaner architecture • Increased scalability without full system rewrites3 works in Mobile AppLocated in Kraków, PolandFrom €1,000 for Mobile AppWorked in Marketing & Advertising (+3)Speaks English, Polish1-10 membersAslan Interactive,Inc.

(0 review)A partner to those companies that want to fully realize their potential.
philosopht is a software house that builds custom software—web, mobile, and desktop applications, as well as IT systems that support companies’ day-to-day operations. We guide clients from the initial brief all the way to a fully functional, maintained product: we don’t start with code, but with workshops at your company, during which we get to know your team, processes, and real-world business context. We work within a clearly defined process. Just one day after the workshops, you receive a clickable mockup; within the first week, a full UI/UX prototype; and then the architecture, timeline, and budget—all approved together before development begins. We meet with you regularly. You see in real time what has actually been created and know what will appear in the next iteration. After deployment, we stay with you—hotfixes, new modules, and feature expansion. We tailor the tech stack to the problem, not the other way around. Web: React, Vue, Next, Nuxt — dashboards, admin panels, SaaS. Mobile: React Native for speed, native iOS/Android where every frame counts. Systems: ERP, CRM, integrations, business process automation. Desktop: Electron on Mac, Windows, and Linux, with offline-first mode when needed. We don’t limit ourselves to code. We have a legal team specializing in tech law (terms of service, GDPR, etc.), a dedicated marketing team, social media and SEO management, and product visibility optimization across language models—ChatGPT, Claude, Perplexity. We also give our clients access to our network of founders, lawyers, and marketers from “nascent unicorns.” We speak business, not jargon. We justify technical decisions in terms of cost, implementation time, and impact on the product. We have over 20 commercial projects and thousands of hours of experience under our belt.Looking for work in Mobile AppLocated in Kielce, PolandFrom €5,000 for Mobile AppWorks in multiple industriesSpeaks English, Polish1-10 membersIntegrio Systems

(0 review)https://novelvision.pl/
Novel Vision is a Warsaw-based web development studio founded by Łukasz Lipski and Yurii Vorotnyy, specializing in Next.js migrations, performance optimization, and headless e-commerce. We help small and mid-sized businesses, especially service companies running active Google Ads campaigns, replace slow WordPress sites with fast, conversion-focused Next.js builds. We also partner with non-technical founders to turn early-stage product ideas into working mobile apps and digital platforms. Our core insight: a slow, poorly structured website doesn't just look dated, it quietly raises your Google Ads costs (through lower Quality Scores) and loses conversions you're already paying to attract. We fix that at the source, rebuilding sites in Next.js for sub-1-second load times, restructuring page architecture around what your own data shows actually converts, and setting up SEO from day one instead of retrofitting it later. What sets us apart: Direct access, no account managers. You work straight with the developers building your project, people who understand both the tech and the business side. Data over guesswork. We analyze your Google Ads and Analytics data before recommending anything, and we'll tell you honestly when a migration isn't worth it yet. Fast turnaround. Websites in about 2 months, mobile apps in 3–4, often starting the day after you approve the scope. No lock-in. You get full source code and ownership. If you ever want to leave, you can, with everything intact. Real results, not promises. Clients like LaserCamp (+164% conversions, -42% CPA, +62% organic traffic) and FrameRent (doubled rental revenue) back this up with numbers, not testimonials alone. For founders building mobile apps or digital products, we handle the full journey, from branding and UX to cross-platform development in React Native, so you get one team instead of juggling four different vendors. Every client we've worked with so far has come through referrals from other satisfied clients.Looking for work in Mobile AppLocated in Warsaw West County, PolandFrom €9,300 for Mobile AppWorks in multiple industriesSpeaks English, German(+1)1-10 membersConcept21
