5(7 reviews)Scalable systems for complex business operations — delivered with clarity and predictability.
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 membersDelante SEO/SEM Agency

(0 review)Holistic digital support — websites, technical support, and consulting, from one developer.
Szympanstudio is a one-person web development studio run by Szymon Jankowski, based in Poland and working 100% remotely for over 10 years with clients across Europe and beyond. I design and build full-stack websites and web applications — from simple business sites to more complex projects with custom backends, integrations, and business logic — on modern architecture (Next.js/React) rather than assembled from CMS plugins. Beyond launch, I provide ongoing technical support: updates, security, backups, monitoring, and fast incident response when something breaks. When a project needs direction before a build starts, I also offer consulting and audits — evaluating an existing site's technical health, security, and performance, and helping clients make informed decisions before committing budget. What sets this apart from a typical agency engagement is continuity: one person across the whole process, from the first conversation through design, development, and long-term maintenance — no hand-offs between departments, no lost context, no rotating account managers. I've delivered full-stack work for clients including Lower Street, Brands in Audio, and buttter.fr, where performance and clean technical execution mattered as much as design. I work in both Polish and English, communicate directly and predictably, and I'm equally comfortable building something new or taking over and stabilizing a site a previous developer left in bad shape.Looking for work in Web ApplicationLocated in Pleszew, PolandFrom €1,000 for Web ApplicationWorks in multiple industriesSpeaks English, Polish1-10 memberscklicky.com
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 membersphilosopht
(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 Web ApplicationLocated in Kielce, PolandFrom €5,000 for Web ApplicationWorks in multiple industriesSpeaks English, Polish1-10 membersIntegrio Systems
