Mougang Thomas Gasmyr

I'm a Senior Full Stack & AI Engineer with 11+ years building scalable, secure web applications for US companies (Gluu, IQVIA), now extending that foundation into production-grade AI systems. I specialize in React, TypeScript, Java, Spring Boot, Python, Identity & Access Management (OAuth 2.0, SAML, OIDC), and LLM-powered application development (RAG, multi-agent systems, fine-tuning).

WHAT I DO BEST:

• AI Engineering: Build production LLM applications — RAG pipelines, multi-agent systems, fine-tuned models, and tool-using AI agents deployed to AWS, GCP, and Azure
• FullStack Development: Modern React frontends with TypeScript and robust Java/Spring Boot or Python backends
• Identity & Access Management: OAuth 2.0, SAML, OIDC, SSO implementations that secure your users
• Microservices Architecture: Design and deploy scalable microservices with Spring Boot
• API Development: RESTful APIs handling millions of requests with sub-100ms response times
• Healthcare Tech: FHIR/HL7 integration, EMR/EHR systems, HIPAA-compliant solutions
• Performance Optimization: Reduce load times by 40%+, improve database query performance by 30%+

PROVEN TRACK RECORD:

✓ Built identity orchestration platform serving 10k+ developers (Agama Lab - Linux Foundation)

✓ Graduated from Andela's AI Engineering Bootcamp — a 10-week intensive program led by Ed Donner, covering RAG, multi-agent systems, fine-tuning (QLoRA), and MCP for production AI systems ✓ Built CodeShield a multi-agent code review bot with 4 specialized agents collaborating

✓ Reduced deployment time by 40% through Jenkins CI/CD pipeline implementation

✓ Achieved 80% test coverage across microservices using JUnit, Mockito, integration tests

✓ Processed 500K+ patient records daily with 99.9% uptime in healthcare systems

✓ Improved API performance by 30% through caching, query optimization, load balancing

✓ Integrated MFA systems (Twilio, DUO, Okta) supporting 100K+ daily authentications

TECH STACK:

• Frontend: React, TypeScript, Next.js, Redux, Vite, JavaScript, Material-UI, Chakra UI
• Backend: Java, Spring Boot, Spring Security, Quarkus, Jakarta EE, Python (FastAPI), Microservices
• AI / GenAI: LLM application development (Claude, GPT-4, open models via HuggingFace), RAG pipelines, multi-agent systems, AI agents & tool use, function calling, MCP (Model Context Protocol), QLoRA fine-tuning, prompt engineering, LLM evaluation & guardrails
• AI Frameworks & Tooling: LangChain, HuggingFace, Gradio, OpenAI SDK, Anthropic SDK, Claude Code, Cursor
• Vector & Embeddings: pgvector, embeddings models, semantic search, hybrid retrieval
• AI Infrastructure: AWS (Bedrock, Lambda, Aurora Serverless, SQS), GCP, Azure for production AI deployments
• Database: PostgreSQL, MySQL, MongoDB, Redis, DynamoDB
• Cloud & DevOps: AWS (EC2, S3, RDS, Lambda), Docker, Kubernetes, Jenkins, CI/CD
• Security: OAuth 2.0, SAML, OIDC, RBAC/ABAC, OWASP Top 10, JWT, Cedar
• Testing: JUnit, Mockito, Selenium, pytest, Integration Testing, TDD, LLM evaluation harnesses

REMOTE WORK VETERAN:
