I help businesses make the right technical decisions and build reliable software.
I work individually on consulting and small projects. For large-scale tasks, I build a team of trusted specialists.
About My Approach
I believe in a personal approach and transparency. You always know who you're working with and who's responsible for the result.
Consulting and audits - I personally work with every client
Small projects - I develop independently
Complex or urgent tasks - I assemble a team for specific project needs
Any format - I personally participate in every project and control quality
No corporate bureaucracy. Only fast decisions and quality results.
Services
What I do:
Technology stack selection - analyze your business goals, budget, and timeline to select optimal technologies
Technology migration — develop a safe transition strategy without business interruption
Scalability architecture — design systems that handle load growth and user base expansion
Cost optimization — find ways to reduce infrastructure and development costs
Strategic planning — help create a 6-12 month technical roadmap
Technical expertise — assess complexity, risks, and plan feasibility
For whom:
Startups at the technology selection stage
Companies planning to scale
Businesses with technical debt or legacy solutions
Leaders without technical background who need an independent opinion
Format:
I work individually — conduct meetings, analyze your project, prepare recommendations. Available for both one-time consultations and regular technical support.
Portfolio
Real projects from idea to production — from startups to enterprise solutions
My own projects and client solutions — from startups to enterprise systems. Beyond what's showcased, I have extensive experience working with numerous clients on commercial projects.
Uptime monitoring service with HTTP, TCP, DNS and heartbeat checks every minute from 6 AWS regions across 3 continents. Every outage is double-checked from a second region before paging the team — alerts fire on real problems, not false positives from flaky networks. EU-hosted, GDPR-compliant, built entirely on AWS.
Business Impact:
Public beta launched — the full feature set (every check type, status pages, Slack/Discord/webhook alerts, SSL expiry monitoring) available free. EU data residency and GDPR compliance by default, with zero cookie tracking or ads
Technical Achievements:
Multi-region AWS architecture — probe workers deployed across 6 regions (Frankfurt, Dublin, N. Virginia, Oregon, Singapore, Tokyo) with second-region confirmation to eliminate false alerts
Event-driven backend — SQS, SNS, and EventBridge for async check scheduling, result aggregation, and alert fan-out
Hybrid storage — Aurora PostgreSQL for account data and configuration, DynamoDB for time-series metrics and incident history
EU data residency — account data and monitor history live exclusively in the EU; global probe workers ship results back to a central EU region
AWS Cognito for authentication (email/password, GitHub SSO, MFA for admins), SES with DKIM-signed alerts, CloudFront + S3 for the frontend, Route 53 for DNS
Go-based probe engine for high-concurrency execution of thousands of checks per minute; Node.js/TypeScript API + React/Vite SSG frontend with 11-language i18n
