I design and build the server-side systems that power web applications, SaaS products, and business platforms. Reliable architecture, clean APIs, and infrastructure that scales with your growth.
When you hire a freelance backend developer, you get direct access to a senior engineer without the overhead of an agency or the delays of a large team. I work as a one-person development partner: you explain the business problem, and I deliver a working system — from database schema to deployed production server.
Most businesses reach a point where off-the-shelf tools stop being enough. Maybe your CRM does not talk to your e-commerce platform. Maybe your app needs a custom API that no plugin can provide. Maybe you have outgrown spreadsheets and need a real backend with proper data modeling, authentication, and automation. That is where I come in.
I have spent years building commercial backend systems for startups and established businesses across Europe. My approach is pragmatic: I choose the simplest architecture that solves the problem, avoid unnecessary complexity, and focus on delivering business value within predictable timelines. Every project starts with understanding what you actually need — not what looks impressive on a technical diagram.
Working with a freelancer means faster communication, lower costs compared to agencies, and a single accountable person who understands your system end-to-end. I handle discovery, architecture, development, deployment, and post-launch support — the full cycle.
My backend development services cover every layer of server-side engineering, from API design to infrastructure management. Here is what I deliver on a typical project.
I build clean, well-documented REST APIs using Django REST Framework. Whether you need a public API for mobile apps, a private API for internal tools, or a webhook-driven integration layer, I design endpoints that are intuitive for frontend developers and reliable under load. Proper serialization, pagination, filtering, versioning, and error handling are standard in every project.
A solid data model is the foundation of any backend. I design PostgreSQL schemas that reflect real business logic, write efficient queries, set up proper indexing, and optimize slow spots before they become bottlenecks. For caching and session management, I use Redis to keep response times fast without overcomplicating the architecture.
Payment gateways (Stripe), CRM systems, Google Shopping feeds, Telegram Bot API, email services, shipping providers — I have integrated dozens of external APIs into Django backends. I handle authentication flows, error recovery, rate limiting, and data synchronization so that your systems talk to each other without manual intervention.
Slow backends lose users and money. I profile Django applications to find real bottlenecks — whether it is N+1 queries, missing indexes, unoptimized serializers, or blocking I/O. I implement targeted fixes: query optimization, caching strategies with Redis, background task offloading with Celery, and connection pooling. The goal is measurable improvement, not premature optimization.
I deploy and maintain production servers using Docker, Nginx, Gunicorn, and CI/CD pipelines. I set up automated deployments, SSL certificates, environment management, log monitoring, and backup strategies. Your application runs on a properly configured Linux VPS with zero-downtime deployments — not on a fragile manual setup.
Not everything can happen in a single request-response cycle. I use Celery with Redis as a message broker to handle email sending, report generation, data imports, periodic cleanup, and any other task that should run asynchronously. Properly managed task queues keep your API fast while heavy work happens in the background.
I work with a proven set of technologies chosen for reliability, ecosystem maturity, and developer productivity. This is not a list of buzzwords — these are the tools I use daily on production systems.
Python is my primary language — I have used it across every type of backend project, from simple scripts to multi-service architectures. Django and Django REST Framework are the backbone of most systems I build: batteries-included, well-documented, and battle-tested in production at any scale.
PostgreSQL handles data storage with reliability and advanced features like JSONB fields, full-text search, and schema-per-tenant isolation for SaaS applications. Redis provides caching, session storage, and acts as a message broker for Celery task queues.
For infrastructure, I containerize everything with Docker, serve through Nginx, and automate deployments via CI/CD pipelines. The result is a reproducible, maintainable setup that any developer can pick up and work with.
Hiring a freelancer is a trust decision. Here is what sets my work apart and why clients come back for repeat projects.
I have delivered over fifteen production systems — from e-commerce platforms and SaaS products to real estate portals and AI-powered chatbots. This is not theoretical knowledge. Every architecture decision I make is informed by real production experience, real bugs, and real user feedback.
I do not just write code and hand over a ZIP file. I handle the entire lifecycle: requirements analysis, system design, iterative development with regular demos, server deployment, monitoring setup, and post-launch support. You get a partner who owns the outcome, not just the output.
Every technical decision I make is driven by the business goal. I do not over-engineer systems or introduce technology for its own sake. If a simple Django monolith solves your problem better than a microservice architecture, that is what I will recommend — and explain why. The result is faster delivery, lower costs, and easier maintenance.
I keep you updated with regular progress reports, working demos, and honest estimates. If a timeline shifts or a requirement needs rethinking, you hear about it early — not on launch day. I am available on Telegram, WhatsApp, and email, and I respond within hours, not days.
Here are three backend projects that represent the range of systems I build. Each started as a business problem and ended as a production system delivering real value.
A real estate agency in Barcelona needed to replace manual listing entry with an automated system. I built a Django backend with scheduled data imports from external sources, an advanced filtering engine, and an SEO-optimized page structure that generates hundreds of indexable URLs. The system handles thousands of property records, serves filtered search results in under 200ms, and increased organic lead flow by eliminating the publishing bottleneck. Stack: Django, Celery, PostgreSQL, Nginx, Docker.
An e-commerce business needed customer retention tools that their existing platform could not provide. I developed a loyalty points engine with event-based triggers, integrated their CRM via API for real-time data synchronization, and built automated product feeds for Google Shopping and Telegram channels. Custom meta fields allowed per-business configuration without code changes. The result was higher repeat purchase rates and a unified data flow across all customer touchpoints. Stack: Django, REST API, CRM API, Google Shopping, Telegram.
A Barcelona-based fashion brand needed a custom online store built entirely from scratch — no Shopify, no third-party platform constraints. I designed and built the full backend: product catalog with category management and image galleries, user authentication, shopping cart and wishlist logic, a loyalty points system, weekly product drop scheduling, and live purchase notifications for social proof. The platform handles the complete purchase flow and gives the brand full control over their data and customer experience. Stack: Django, PostgreSQL, REST API, Docker.
I work with a specific type of client — businesses and teams that need serious backend engineering, not generic web development. Here is who typically hires me:
If you recognize your situation in any of these descriptions, let's talk. The initial consultation is free.
Every project is scoped individually after a free discovery call. Below are typical starting points based on project complexity. All prices are in EUR and include architecture, development, deployment, and initial support.
REST API for a mobile or web app, or integration with a third-party service (payment, CRM, marketplace). Typically 1-3 weeks.
Complete backend system: database design, API layer, authentication, admin panel, deployment. Typically 4-8 weeks.
Multi-service architecture with advanced integrations, task queues, high-load optimization, and ongoing support. 8+ weeks.
Tell me about your project — I will propose an architecture, estimate the timeline, and give you an honest assessment of what it takes. The initial consultation is free.
