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 rewrites4 works in Web ApplicationLocated in Kraków, PolandFrom €1,000 for Web ApplicationWorked in Marketing & Advertising (+3)Speaks English, Polish1-10 membersBrand Backup

We help growing and established companies turn complex software initiatives into clear, scalable, and well‑managed systems. Our job is more than just software design and development — our job is taking care of your success. We don't jump straight into development. We start with discovery, solution design, and business analysis to define scope, architecture, integrations, and priorities before a single line of code is written. This is how we reduce delivery risk and protect your budget. We focus on three solution domains: 1. Custom Business Systems & Operational Platforms 2. Mobile Products for Customers and Operations 3. AI‑Enabled Business Workflows (AI under senior engineering control) Our strongest industry experience is in Food & Beverage, Real Estate, and FinTech — with growing expertise in iGaming, EdTech, and Travel Tech. Why companies choose us: clarity before development, structured delivery with PM and QA, domain‑aware solutions, and AI‑accelerated senior engineering. We work best with growing mid‑market companies, multi‑location businesses, and organisations that have outgrown spreadsheets or disconnected tools. We work as an extension of your business, in tight communication and total transparency — so there's no waste of time on back‑and‑forth. Start with a Solution Discovery call – to clarify scope, architecture, and the right path before any build commitment.31 works in Web ApplicationLocated in Tuckahoe, United States (+3)From €10,000 for Web ApplicationWorked in Education (+23)Speaks English, German(+2)51-200 membersSKM Group
