I am Adrian Sawicki, a Senior Software Engineer with over 10 years of experience designing and building scalable backend systems, distributed architectures, and data-driven platforms. My expertise spans Python, C#/.NET, Java, and Node.js, with a strong focus on high-performance APIs, cloud-native solutions, and real-time data pipelines across AWS, GCP, and Azure. Over my career, I have delivered impactful solutions in industries including fintech, trading, and SaaS, leading migrations to microservices, implementing CI/CD pipelines, and integrating secure payment and third-party APIs. I also developed AI/ML-driven features that improved personalization and customer engagement. What sets me apart is my ability to combine deep technical knowledge with business impact: reducing infrastructure costs by 25%, cutting system latency by 50%, and achieving 99.9% uptime for mission-critical applications. Beyond coding, I mentor teams, enforce best practices, and collaborate with stakeholders to align technology with strategic goals. I am passionate about solving complex engineering challenges, scaling platforms that handle millions of data points, and building reliable systems that drive business success.…I am Adrian Sawicki, a Senior Software Engineer with over 10 years of experience designing and building scalable backend systems, distributed architectures, and data-driven platforms.
