I am a lawyer, academic writer, English-Spanish translator and Wikipedia expert. I have studied English at a prestigious language institute in Argentina for 10 years. The extensive education obtained at the institute allowed me to start teaching this language to different groups of students. In addition, I started working as a freelance translator for different websites where I have translated documents, videos and audios from English to Spanish (and vice versa) on a wide variety of subjects. Besides my knowledge of English, I studied law at the National University of La Plata (50 km away from Buenos Aires) and started working as a lawyer in different law firms. I gained a lot of experience in handling legal cases, so I used my legal knowledge to explore my other passion: writing. I started writing and translating different legal documents and nowadays one of my specialties in translation and writing is the legal field. My passion for writing did not stop at the legal field. I explored other fields to become a multifaceted academic writer. At the same time, I started to learn other skills such as creating content for Wikipedia. I have been creating and editing articles for Wikipedia for several years now, knowing its publishing rules to perfection. I love writing as well as translating. I am a very creative person and I am always willing to go the extra mile to ensure an outstanding result in every assignment. In addition, I am part of a group of native Italian, French and Portuguese translators. So we offer translation services from English to Italian, French and Portuguese (and vice versa). If you want a translator or writer who works hard and is reliable for your work, I am the person you are looking for. I look forward to working with you!

We are a software development team focused on building custom digital solutions for businesses that need more than just code — they need clear execution, technical depth, and reliable delivery. What started as a solo freelance practice has evolved into a flexible team of specialists. This allows us to adapt to the real needs of each project: when a task is best handled by one expert, we keep the process lean and direct; when a project requires broader coverage, we work as a coordinated team across multiple technologies. Clients work directly with professionals involved in the actual execution of the project. We value clear communication, strong ownership, practical problem-solving, and software that is built to be maintainable, scalable, and useful in the real world. Our team works across a wide range of technologies, including: Python / Django, PHP, JavaScript, MySQL, C# / .NET / .NET Core, WordPress, custom WordPress plugins, Svelte, Angular, Flutter, HTML5, Stripe, Google Maps API, GPS, Cartography & Maps, and n8n automation. We help businesses with: • Custom web application development • Backend systems and API development • Frontend implementation with modern frameworks • Mobile and cross-platform app development • WordPress custom development and plugin creation • Payment gateway integrations • GIS, mapping, and geolocation-based platforms • Workflow automation, integrations, and process optimization with n8n • Technical planning, architecture, and scalable product development Our structure is flexible by design. Some projects only need one highly specialized developer. Others benefit from a broader team working together across backend, frontend, mobile, integrations, automation, and deployment. We can do both efficiently. We are not focused on delivering generic solutions. We build software tailored to the goals, constraints, and growth plans of each client. Whether the need is a custom platform, a business-critical integration, an internal tool, a mobile app, or a complete product from scratch, we aim to deliver solutions that create real value. Our track record here reflects the seriousness, consistency, and quality we bring to every project. Let’s build something solid, scalable, and valuable together. We also offer English–Spanish translation. Since we build multilingual sites, we keep a translator in-house — copy and UI strings are localized as part of the build, not outsourced afterwards.

A web developer builds, codes, and maintains websites and web applications, turning designs and requirements into functional, responsive sites using languages like HTML, CSS, JavaScript, and back-end frameworks. Hiring a freelance web developer gives you direct access to the technical skill set required to ship a working product, whether that is a marketing site, an e-commerce store, a custom web app, or an API-driven platform. The right developer translates business goals into clean code, fast load times, and a maintainable codebase your team can build on.
A web developer handles the technical build of a website from concept through launch and ongoing maintenance. They write the front-end code that users interact with, the back-end logic that powers features, and the integrations that connect your site to payment gateways, CRMs, analytics, and third-party APIs. Most freelance web developers specialise in one of three areas: front-end, back-end, or full-stack development.
Common deliverables from a freelance web developer include:
A capable web developer is fluent in the core languages of the web and one or more frameworks suited to your stack. Front-end work centres on HTML5, CSS3, JavaScript, and TypeScript, with frameworks like React, Next.js, Vue.js, Nuxt, Angular, and Svelte. Styling systems often include Tailwind CSS, Bootstrap, or Sass.
On the back-end, developers commonly work with Node.js, Express, PHP and Laravel, Python with Django or Flask, Ruby on Rails, Java Spring, or ASP.NET. Database experience typically spans relational systems like MySQL and PostgreSQL alongside NoSQL options such as MongoDB and Firebase. Version control with Git and GitHub or GitLab is standard, and many developers also work with Docker, AWS, Vercel, Netlify, and Cloudflare for deployment and infrastructure.
For content-managed sites, expect proficiency with WordPress, Shopify Liquid, Webflow, Drupal, or headless CMS platforms like Strapi, Contentful, and Sanity.
Freelance web developers serve every sector that needs an online presence or a digital product. Common engagements include:
The strongest signals of a competent freelance web developer are a portfolio of live, working sites, a public code repository, and clear communication about technical trade-offs. Look for project diversity that matches your stack, evidence of responsive design, and Lighthouse or Core Web Vitals results that demonstrate performance awareness. Client reviews on Freelancer.com that mention on-time delivery, clean handoffs, and post-launch support carry significant weight.
Useful interview questions to ask a shortlisted candidate:
Freelancer.com hosts one of the largest pools of vetted web developers in the world, spanning every framework, CMS, and specialisation a project might require. You can review verified portfolios, ratings from completed projects, and written client reviews before shortlisting, and you can compare competitive bids from developers across multiple time zones. Whether you need a single landing page or a long-term engineering partner, the marketplace scale on Freelancer.com makes it straightforward to find the right match. Milestone Payments protect your budget by releasing funds only when agreed deliverables are met.
Ready to build or rebuild your site with the right technical partner?
Hiring the right web developer comes down to a clear brief, careful review of bids, and a final shortlist based on portfolio evidence and reviews. The process below walks through how to scope your build, compare proposals, and award the project with confidence.
The quality of your project post directly determines the quality of the bids you receive. A specific brief filters out mismatched freelancers and attracts developers whose stack, experience, and portfolio align with what you actually need to build. Head to the
Bids are short proposals, not just price tags. A strong web developer will outline their proposed approach, raise sensible technical questions, and suggest a realistic timeline rather than simply agreeing to everything in the brief. Read each proposal carefully and use Freelancer.com's chat to clarify anything before shortlisting.
Your final decision should combine proposal quality with profile evidence. Review portfolios for projects similar to yours in stack and complexity, and weigh consistency across multiple completed jobs rather than relying on a single standout example. Written client reviews often reveal how a developer handles changes, deadlines, and communication.
A simple brochure or landing page can be built in a few days, while a custom WordPress or Shopify site typically takes two to six weeks. Larger web applications with custom back-ends, user accounts, and integrations usually run two to six months depending on scope and team size.
A web designer focuses on visual layout, user experience, and producing mockups in tools like Figma. A web developer takes those designs and writes the code that turns them into a working website. Some freelancers offer both services, but for complex builds it is common to hire each role separately.
Front-end developers handle the visible interface, back-end developers build the server logic and databases, and full-stack developers cover both. For small to mid-sized projects a full-stack developer is often the most efficient choice, while larger applications benefit from specialists working together.
Yes. Many freelancers on Freelancer.com offer retainer arrangements covering security updates, plugin upgrades, bug fixes, performance monitoring, and small feature additions. You can structure the engagement as a recurring monthly project or pay per task as needs arise.
A freelance web developer is usually the better fit for focused builds, defined scopes, and budget-conscious projects. Agencies suit large, multi-disciplinary programmes that need dedicated project management, design, development, and QA running in parallel.
