About Bogdan

I help businesses design and ship production-grade AI systems and scalable cloud infrastructure — from agentic LLM workflows and multi-agent architectures to AWS platform engineering and DevOps automation. With 15+ years of hands-on experience across the full technology stack, I bridge the gap between cutting-edge AI capabilities and reliable, production-ready backend systems.
What I specialize in:

Agentic AI & LLM systems: LangGraph, LangChain, Amazon Bedrock, Anthropic Claude, ReAct & Plan-and-Execute agents
Retrieval-Augmented Generation (RAG): pgvector, Pinecone, Azure AI Search, document ingestion pipelines
Multi-agent orchestration with typed state management, checkpointing & structured outputs
Model Context Protocol (MCP) integration & prompt engineering with guardrails
AWS cloud architecture: EC2, Lambda, RDS, DynamoDB, ECS, S3, CloudFront, VPC, IAM, KMS, WAF
AI-powered contact centers: Amazon Connect, Lex V2, Amazon Q, Contact Lens, sentiment analytics
Infrastructure as Code: Terraform, Docker, Kubernetes, Helm, Ansible
CI/CD pipelines: GitHub Actions, GitLab CI, Jenkins, ArgoCD
Backend microservices & API design: Python, FastAPI, Node.js, TypeScript
Observability & monitoring: OpenTelemetry, CloudWatch, Prometheus, Grafana
FinOps & cost optimization: right-sizing, Savings Plans, Spot Instances

Certifications: AWS Certified Solutions Architect – Associate · Claude in Amazon Bedrock (Anthropic)
Dual academic background in Computer Science & Economics — I deliver solutions that are both technically sound and aligned with business goals. Available for remote B2B engagements.

    September 2022 - April 2026 (3 years and 7 months)
    Bucharest, Romania
    • • Architected and deployed production-grade multi-agent AI systems using LangGraph and Anthropic Claude via Amazon Bedrock, implementing directed graphs with typed state management, checkpointing, and structured outputs for reliable enterprise execution.
    • • Designed end-to-end RAG frameworks using pgvector and Pinecone to optimize high-dimensional data retrieval and ensure deterministic validation of LLM outputs for automated decision-making.
    • • Led integration of LLM-driven automation into enterprise workflows via Python (FastAPI) microservices and AWS Lambda, leveraging durable orchestration patterns to transform probabilistic model behavior into predictable business logic.
    • • Designed and implemented AI-powered contact center solutions using Amazon Connect, Lex V2, Lambda (Python), Amazon Bedrock, Amazon Q, and Contact Lens — covering conversational self-service, real-time transcription, sentiment analytics, and agent escalation logic.
    • • Established observability and monitoring frameworks for GenAI workloads using CloudWatch and OpenTelemetry; tracked real-time model accuracy, evaluation loops, critic/retry patterns, and guardrails to ensure system reliability and content safety.
    • • Led design and delivery of distributed AWS-based infrastructure platforms; owned architecture decisions across scalability, reliability, security, and cost governance.
    • • Built reusable Terraform modules enabling self-service environment provisioning; reduced configuration drift across multiple workstreams.
    • • Designed HA AWS architectures achieving 99.9% uptime; implemented automated scaling, monitoring baselines, and incident prevention practices.
    • • Defined and implemented security governance standards: IAM policies, KMS encryption, WAF rules, and Secrets Manager across business-critical environments.
    • • Delivered end-to-end AWS migrations using DMS, Migration Hub, and Application Discovery Service with minimal business disruption.

    April 2017 - May 2022 (5 years and 1 month)
    Bucharest, Romania
    • • Designed and operated high-traffic AWS environments (EC2, ELB, VPC, RDS, DynamoDB, S3, CloudFront, Lambda, ElastiCache), focusing on performance tuning and schema optimization.
    • • Automated operational workflows with Python and Bash (patching, snapshots, security audits), reducing manual effort by approximately 30%.
    • • Tuned RDS/DynamoDB performance, introduced ElastiCache caching, and optimized indexing strategies to significantly reduce application latency and support high volumes of concurrent users.
    • • Led cloud migration projects end-to-end for Tier-1 enterprise clients; managed IAM, KMS, Secrets Manager, and WAF security configurations for regulated environments with global data sovereignty compliance.
    • • Implemented strongly typed API contracts, idempotent data pipelines, and automated testing/static analysis (SonarQube) via GitHub Actions and GitLab CI, maintaining high standards of code quality.
    • • Implemented observability standards using CloudWatch and CloudTrail — built dashboards, alerting rules, and anomaly detection workflows to proactively prevent service impact.
    • • Served as primary technical contact for Tier-1 enterprise clients — conducted architecture reviews, launch readiness assessments, and post-incident RCA sessions.
    • • Used Java, TypeScript, Ansible, Maven across development and automation workflows; contributed to CI/CD pipeline design.
