Andrii B. - Fullstack Developer, React Native, nextjs

My journey at Softaims has been defined by curiosity, growth, and collaboration. I’ve always believed that good software is not just built—it’s carefully shaped through understanding, exploration, and iteration. Every project I’ve worked on has taught me something new about how to balance simplicity with depth, and efficiency with creativity. At its core, my work revolves around helping businesses and people achieve more through thoughtful technology. I’ve learned that the most successful projects come from teams that communicate openly and stay adaptable. At Softaims, I’ve had the opportunity to work alongside professionals who challenge assumptions, share knowledge generously, and inspire continuous improvement. I take pride in focusing on the fundamentals—clarity in logic, consistency in design, and empathy in execution. Software is more than a set of features; it’s a reflection of how we think about problems and how we choose to solve them. By maintaining this perspective, I aim to build solutions that are not only effective today but also flexible enough to support the challenges of tomorrow. The culture at Softaims promotes learning as an ongoing process. Every new project feels like a step forward, both personally and professionally. I see each challenge as a chance to refine my skills and contribute to the shared vision of building technology that genuinely improves lives.

Experience Highlights

AWS Cost Reduction | AWS DevOps | Cloud Engineer | Cloud Architect

Problem: Uncontrolled growth in AWS bills. Unclear where money was being spent, with many unused resources. Solution: Conducted a deep audit of AWS spending. Identified unused resources, optimized EC2/RDS instance sizes, implemented Reserved Instances and Savings Plans. Automated S3 lifecycle rules. All changes defined via Terraform.

Deployment Automation: CI/CD for Docker/Kubernetes on AWS | DevOps

Problem: Manual, frequently breaking deployments that took hours. Developers spent too much time on releases instead of coding. High percentage of production errors. Solution: Designed and implemented fully automated CI/CD pipelines (GitHub Actions + AWS EKS/ECR) for microservices on Docker/Kubernetes. Integrated automated testing, security scanning, and monitoring.

Real-time Data Processing for IoT | AWS DevOps | Cloud Engineer

Problem: Client needed to collect and process massive volumes of real-time data from IoT devices. Existing solutions couldn't handle the scale and required significant investment. Solution: Designed and built a new Serverless platform on AWS: API Gateway for incoming data, AWS Lambda (Node.js) for initial processing, Kinesis/SQS for buffering, and S3/DynamoDB for storage.

Cost & Scalability Optimization: Migrating Monolith to AWS Serverless

Problem: Existing monolithic Node.js backend suffered from high operational costs, poor scalability under peak loads, and slow feature release cycles due to manual deployments. Solution: Redesigned and rewrote key services to AWS Lambda (Node.js) with API Gateway for APIs and DynamoDB for data. Fully automated Serverless deployment via CI/CD pipelines.

Unit test example | Node.js Developer | Back-end Developer

Here’s an example of a unit test for a Node.js backend project built with NestJS, showcasing best practices in testing scalable APIs and services using TypeScript, Jest, and modern Node.js development standards.
