Summary
Experienced Enterprise Test Architect with 17+ years designing and implementing enterprise‑scale automation frameworks across diverse industries. I lead enterprise architecture modernization at Signant Health and, since 2023, have been advancing AI‑augmented testing across LLMs, RAG systems, multi‑agent orchestration, and enterprise MCP implementations. In this role I drive strategic technical direction, perform gap analyses between current and target architectures, and lead modernization initiatives that reduce redundancies across the enterprise. I’ve led significant reductions in regression cycle time while improving reliability. I build scalable automation from scratch, work across multiple programming languages and cloud platforms, mentor teams, and deliver measurable outcomes.
Core expertise:
- enterprise-scale test automation frameworks and strategy (Python, Java, Ruby, .NET/C#) tailored to business and architectural requirements
- AI-augmented testing since 2023: LLMs, RAG, multi-agent orchestration (CrewAI), Model Context Protocol (MCP), and AI-human workflow automation (n8n)
- cloud-native and DevOps practices: AWS, CI/CD, Infrastructure as Code (Terraform, Packer), containerization (Docker, Kubernetes)
- performance, security testing, and ethical hacking integrated into test strategy
- data analytics dashboards (Dash, Pandas) for actionable quality insights
- consultancy, mentoring, and knowledge transfer across engineering teams
- clear technical communication using ASR (Architecturally Significant Requirements)
I currently lead enterprise architecture modernization at Signant Health, driving strategic direction, gap analysis, and modernization initiatives that reduce redundancies across the enterprise.
I hold a bachelor’s degree in Business Information Systems (2008), ISTQB Foundation certification (2009), and a master’s degree in Management Information Systems (2010).

Before the global pandemic I joined Signant Health to continue my path as a Test Automation Architect in a different, exciting industry.
Signant enables clinical trials across traditional, virtual, and hybrid designs and helped Pfizer develop the COVID‑19 vaccine in record time through technology and innovation.
Achievements:
- Built Analytics Dashboard (Dash, Pandas) to analyze legacy test results in real time, provide high‑level overviews (pass rate, duration), cluster defects, compare runs, and identify flaky tests
- Revived performance testing by building a tool capable of simulating millions of users to load test applications (AWS, deployed with Terraform)
- Migrated jobs from legacy Jenkins to the latest version using Pipeline as Code
- Implemented Disaster Recovery tests to validate system resilience and recovery from disasters
- fast reliable feedback on regression tests -> reduce duration from 13 hours to 3 hours, increase passing percentage to 99%
- Built a Python package for integrating tests with Jira XRAY: automatic test case generation and execution status updates
- Enhanced Docker images used in tests, reducing size from 4GB to 600MB—cutting download costs and enabling faster feedback
- Reduced technical debt: migrated code and pipelines from a legacy source control system to the current platform
- AWS Lift & Shift: moved workloads from in‑house infrastructure to the cloud
- Built an automated mechanism to distinguish product bugs from environment issues, reducing manual triage time
)
Same company, same Alfresco client, similar testing issues. A need for a new tool arose, so I took the challenging position of QA Automation Architect to build TAS.
In this role I provided technical leadership and strategic direction for automation testing and contributed to implementing and adopting CMMI (Capability Maturity Model Integration) processes within Ness Iasi.
I worked closely with the solutioning team to define and implement POCs for testing challenges, produced cost/benefit analyses, identified resource requirements, defined project estimates, and authored technical specifications.
I served as the primary point of contact in Romania for Test Automation.
)
New company, new opportunities ahead!
Here I developed and implemented tests in Java for a large customer (Alfresco, now Hyland). Their powerful, highly scalable enterprise content management (ECM) solution needed robust testing to validate different configurations, integrations with Office, Google Docs, and Salesforce, deployment scenarios, and SDK compatibility across versions.
As a Senior Automation Engineer I maintained and modernized thousands of legacy tests that were sometimes brittle, took a long time to complete, or were implemented using various anti‑patterns.
)
Multiple outsourced projects required automation to accelerate the development cycle. In 2012 I became a QA Team Lead, managing more than four projects simultaneously.
I served as a key point for all QA aspects of releases, providing formal feedback based on best practices. For automation I used Ruby as the primary language.
Coaching, solving work problems, and delivering internal training—primarily on automation—were part of the role.
)
I love Ruby as a programming language, so I worked as a Ruby on Rails developer for ~1.5 years. Here I began to apply BDD (Behavior‑Driven Development) to implement and deliver a web application similar to Dropbox.
)
After two years in the field, I continued working at OSF Global Services (now OSF Digital). Here I worked extensively with Ruby to implement foundational frameworks for testing web applications for different customers.
)
Starting my career in testing as a QA Engineer. Here I learned how to design, develop, and execute tests across common and uncommon use cases, including performance, stress, and stability testing to ensure software quality. At Embarcadero I learned Delphi as the primary language to automate ERStudio Data Architect.
In 2009 I obtained the ISTQB Certification (Foundation Level).
