About Hammam

Hammam A.Status: Offline
Full-Stack & Cloud Engineer | SaaS, WebGIS, Data-Heavy Systems
Istanbul, TurkeyĀ - 5:44 pm local time
I help founders, startups, and organizations build production-ready software systems , I build production-grade software systems designed to scale, perform, and remain stable under real-world usage. I do not build fragile demos, slow mapping applications, or systems that require rebuilding after launch. I am a Full-Stack Software Engineer and GIS Developer with over four years of hands-on production experience delivering SaaS platforms, WebGIS systems, real-time dashboards, and data-intensive web applications across enterprise and startup environments. My background includes work with Sainsburyā€™s (UK) on large-scale enterprise systems, ANKAGEO (Turkey) on LIDAR visualization and real-time geospatial streaming platforms, Exbitx on live DeFi analytics dashboards and blockchain data infrastructure, and Gooreo on marketplaces, healthcare platforms, and CMS-driven products. This experience has shaped a practical, architecture-first approach focused on performance, scalability, and long-term maintainability.

My core expertise lies in SaaS and cloud-native platform development. I design and build secure, scalable backend systems using Node.js and Java (Spring Boot), develop performance-focused React and Next.js frontends, and implement real-time architectures using WebSockets, Redis, and Kafka. I work with containerized deployments, CI/CD pipelines, and AWS-based infrastructure to ensure systems are production-ready from day one. When working with founders, I focus on building MVPs that are structured to evolve into scalable platforms rather than disposable prototypes.

In WebGIS and geospatial engineering, I specialize in building full spatial systems rather than simple map interfaces. My experience includes architecting LIDAR visualization modules, real-time geospatial streaming systems, spatial ETL pipelines, and optimized PostGIS databases. I solve common GIS challenges such as messy spatial data ingestion, slow map rendering, inefficient spatial queries, and real-time location tracking. My stack includes Mapbox GL JS, Leaflet, OpenLayers, PostGIS, PostgreSQL, GeoServer, GeoDjango, GDAL, GeoPandas, and vector tile pipelines. The focus is always on performance optimization through spatial indexing, vector tiling strategies, efficient query design, and scalable infrastructure.

I also develop advanced 3D and data visualization systems using Three.js and React Three Fiber when the product requires immersive or high-density visual representation. My work includes real-time 3D dashboards, geospatial scenes, digital twins, and performance-optimized rendering pipelines using instancing, level-of-detail strategies, and GPU-aware optimizations. The emphasis is on production reliability rather than visual experimentation.

When WordPress is the appropriate solution, I implement it with engineering discipline. This includes custom theme development, structured CMS architecture, WooCommerce optimization, Core Web Vitals performance tuning, plugin rationalization, and headless CMS configurations. The objective is to deliver secure, maintainable systems rather than plugin-heavy builds.

What differentiates me from many freelancers is a systems-oriented mindset. I prioritize architectural planning before implementation, design for scalability from the outset, optimize early, and conduct feasibility checks before development begins. My approach is shaped by enterprise systems, geospatial platforms, and data-heavy applications where performance and reliability are not optional.

My technical stack includes React, Next.js, TypeScript, Vue.js, Node.js, Java Spring Boot, REST APIs, WebSockets, Redis, Kafka, PostGIS, PostgreSQL, GeoServer, Mapbox GL JS, GDAL, Three.js, AWS, Docker, Kubernetes, CI/CD pipelines, and WordPress-based CMS systems. I am new to Upwork as a platform but not new to building production systems. My current rates reflect a strategic effort to establish long-term partnerships while delivering senior-level engineering execution. If you are building a serious SaaS product, geospatial platform, real-time system, or data-intensive application and require it to be architected correctly from the beginning, I am available to discuss your project.
