Started Python on January 26, 2026 and passed AWS Solutions Architect Associate (SAA-C03) in April with 809/1000. Since summer I have been building IntegraHolistic — a production SaaS for holistic cosmetology and trichology clinics, created together with a practicing cosmetologist. Health data, done properly: a dedicated AWS account in an Organization, SCPs, Identity Center with MFA, KMS encryption and a daily security watchdog.
"I like to crack problems and put together puzzles. Troubleshooting is my natural path — step by step to the solution. That satisfaction of 'It works!' drives me every day. After 14 years in private cloud — it's time to rise higher."

Production SaaS for holistic cosmetology and trichology clinics, co-created with a practicing cosmetologist. Client records and interviews, the Holistic Action Plan generator, consents signed on a tablet, treatment packages, team schedule, revenue and commissions, voice notes. Health data under GDPR art. 9: dedicated production account in an AWS Organization with SCPs, Identity Center with MFA, KMS encryption, WAF, EU-only data residency and a daily security report.
Secure web app for psychologists and psychotherapists: session notes that become immutable once signed, digital GDPR consents with full history, appointment calendar (in person and online) and an AI assistant that turns rough notes into a structured summary. AES-256 encryption, MFA, audit log, data stored in the EU (Frankfurt).
Production-grade serverless application for managing garden care plans. Step Functions orchestrates 11 Lambdas to generate yearly care schedules using Anthropic Claude AI, then verifies them monthly against weather forecasts via OpenWeatherMap and sends HTML email proposals through SES. Plant database (~1800 species) imported from Wikidata SPARQL. Frontend hosted on S3 + CloudFront with HTTPS. Full IaC with Terraform Workspaces and zero-keys CI/CD via GitHub Actions + OIDC.
Python CLI tool for managing EC2 instances — list, start, stop, reboot and terminate with selective instance targeting. Includes audit logging to S3 with caller identity tracking via AWS STS. Built with OOP, error handling and daily log rotation.
Full-featured currency converter with live exchange rates via API, conversion history stored in S3, and advanced Pandas analytics reports. Menu-driven CLI with duplicate detection and S3 file management.
Python CLI tool that queries AWS infrastructure and saves a JSON health report to S3. Checks: EC2 instance IDs and states, S3 bucket sizes via CloudWatch, IAM user count with last login, and ELB load balancer types and states.
Python CLI tool that compares EC2 On-Demand prices across AWS regions using the AWS Pricing API. Highlights the cheapest region for any instance type and OS. Live prices reflect current On-Demand rates with OS license costs included.
Next learning project — containerized application on Amazon EKS, deeper Terraform with modules, and CKA preparation. Building hands-on Kubernetes experience to complement serverless skills.
