Software engineering + agentic delivery
Build faster.
Keep it reliable.
I help product and engineering teams build, modernize and operate Java/Kotlin platforms, cloud services and web applications—combining 13+ years of production experience with practical AI-assisted workflows.

Where I can help
From a difficult system
to a dependable one.
Bring in senior engineering where architecture, delivery speed and production quality must work together.
01
Build business-critical products
Java/Kotlin services, web applications, APIs and integrations designed around real business workflows—not technology for its own sake.
- Java, Kotlin & Spring
- React, Angular & TypeScript
- REST APIs & integrations
02
Modernize systems and cloud delivery
Evolve legacy or low-code systems in measured stages, improving maintainability, performance and cloud efficiency while protecting continuity.
- Architecture & migrations
- AWS, cloud & Kubernetes
- CI/CD and observability
03
Adopt agentic engineering responsibly
Use AI agents, clear specifications and automated checks to shorten feedback loops while keeping decisions reviewable and production systems trustworthy.
- Claude Code & GitHub Copilot
- MCP servers & specialized agents
- Specifications & test automation
Evidence from delivery
Improvements you can measure.
Selected outcomes from client engagements across performance, test automation and cloud operations.
- 5×
- smaller Selenium suite while preserving meaningful coverage
- 3×
- processing improvement in a performance-critical workflow
- 35%
- reduction in cloud costs through focused engineering changes
Relevant experience
Complex domains.
Calm execution.
Experience across pharma, IoT, retail, automotive and financial systems—working from product decisions through deployment, incident response and production support.
From low-code constraints to a maintainable product platform.
Helped migrate a business workflow application to a Kotlin and React stack, pairing backend delivery with the DevOps work needed to run it reliably.

Cloud infrastructure for devices that cannot afford guesswork.
Built across device-to-cloud communication, event-driven services and operational visibility—with direct incident-response responsibility.

“The best software delivery feels fast because the thinking is clear—not because the corners are hidden.”
Cristian PopescuSenior Java / full-stack engineer & AI builder
How the work moves
Visible progress.
Fewer surprises.
Every engagement starts with the problem and ends with software your team can understand, operate and continue to evolve. AI supports the work; engineering judgment owns the result.
Check project fit- 01
Shape
Clarify outcomes, constraints and the riskiest assumptions before committing to a solution.
- 02
Design
Choose an architecture and delivery plan that fit the business—not an idealized diagram.
- 03
Build & prove
Use focused agents where they help, then verify every increment with automated checks and feedback around real risks.
- 04
Operate & improve
Make production behavior visible, respond calmly and feed what we learn back into the product.
