Hire the Best Amazon S3 Developers
in Serbia

I am webscraping and data extraction expert. In more than 7 years working in this field, I have scraped more than 1500 different kind of websites (simple html, with javascript, with protection - limited number of requests, with login...) and save data in different formats or databases (.csv, .xls, .json, MySql, MongoDb, AWS DynamoDB, AWS RDS, AWS S3...). One website had ~130 millions of records (simple html and it was done for ~10 days). I am using proxies for rotating IPs so on every request I have different IP address. Also have big experience in scraping e-commerce websites like magento1, magento2, shopify, opencart, bigcommerce, woocommerce.... The tool I am using is my own code written in python, but I can use scrapy too. I am fast, efficient and responsible and I can find solution for most of problems online. So learning new things is not problem for me. If you are interested in collaboration - contact me anytime so we can make a deal. I am in Serbia, Europe, CEST time zone.

I architected a cloud transformation for a major fintech platform that slashed infrastructure costs by 50% in just four months. By redesigning Amazon Web Services clusters with Kubernetes, optimizing Amazon S3 storage classes, and rightsizing Amazon EC2 instances, I turned a bleeding budget into a streamlined operation. I focus on DevOps Engineering and Solution Architecture that aligns technical performance with business profitability, ensuring your infrastructure is not just a cost center, but a growth engine. My approach to DevOps goes beyond basic maintenance; I build self-healing, automated ecosystems. I have engineered scalable Helm-based delivery pipelines for 150+ microservices and executed a zero-downtime migration for an AI-based hiring platform. To support enterprise-grade operations, I led a Salesforce App Development initiative, utilizing Apex and API Integration to sync a Salesforce CRM with external ERP Software. This automation streamlined Accounts Payable and General Ledger reporting, eliminating data silos between engineering and finance. I also implemented Deployment Automation using Terraform and Git, establishing a single source of truth for infrastructure. I possess deep technical fluency across Cloud Engineering and Linux System Administration, managing complex environments on Microsoft Azure and Docker. I have recently architected high-concurrency microservices using Golang and API gateways to handle massive traffic spikes. Whether you need to optimize Customer Relationship Management data flows or harden your CI/CD pipelines, I deliver resilient systems. Let’s discuss how I can architect a solution that scales with your ambition.

✓ 13+ years of commercial software development ✓ Developed award-winning projects ✓ Full-stack developer I started in software development back in 2003 (while in school) and have worked on commercial projects since 2007. At the moment I have huge development experience, web & mobile. I can easily master new technologies if it's required. In the past I won two prestigious software development contests, organized by Samsung and VK, in spite of the platforms (Android & Tizen) were new for me. (VK is the biggest Russian social network and the 9th most visited website in the world) The contests I won required not algorithms knowledge, as usual programmer competitions. These were several weeks long contests, which require strong software architecture experience. It were complex apps which intensively use sockets, REST, long-polling and "push" to communicate with backend, where all domain model is cached in an extremely optimized SQLite database to provide the best user experience, where the model layer heavily uses multithreading and the UI is optimized to be fluent. In this short time frame, there is no room for a mistake. To develop an award-winning app you should have years of software architecture experience. Many apps I've made from scratch to release alone, or with just a small involvement of other developers, so I can estimate the impact of early stage decisions to the whole project development time. I like software architecture, and like to code. It is exciting to learn new technologies and see how these which you know evolves. Whether it's single-page applications, which are a huge step in the web frontend evolution, or it is Kotlin coroutines - which make Java platform multithreading so pleasant. I used many platforms, technologies, languages and frameworks in my life, developed frontend and backend, business apps and fun games. In some of these technologies I am an expert, others I just tried, but I think the overall development experience is much more important than knowledge of a framework or a language, it is especially true for long running projects. I am open for any interesting project, even if I'm currently isn't an expert in the project development stack. Rewards: • My team and I won a competition to develop a messenger on Tizen platform organized by Samsung ($100000 in prizes). The achievement led to an offer from Samsung to work on a VK social network mobile app for Tizen platform. • Won second place in a competition to develop an Android messaging app for VK social network with more than 300 entrants and $100000 in prizes.
