About

Professional summary

I am a Senior Software Engineer with more than seven years of experience building scalable software products across AI, machine learning, backend, cloud, and full-stack engineering. I focus on designing reliable production systems and delivering end-to-end solutions that connect business needs with robust technical implementation.

I specialize in production AI systems, including AI agents, LLM integrations, retrieval-augmented generation pipelines, semantic search, vector databases, and model-serving APIs. My experience includes designing agent workflows with tool calling, orchestration, state management, human approval, structured outputs, and resilient fallback mechanisms.

I build backend platforms using Python, FastAPI, Node.js, Java, and Go, with expertise in REST, GraphQL, gRPC, microservices, asynchronous processing, and event-driven architectures. I have worked extensively with PostgreSQL, Redis, MongoDB, Kafka, and Elasticsearch to support high-volume, distributed workloads.

I am experienced in cloud-native delivery on AWS, using services and tools such as Kubernetes, Docker, Terraform, SageMaker, Lambda, S3, EC2, CI/CD pipelines, and observability platforms. I prioritize reliability, monitoring, security, automated testing, and maintainable architecture.

I also deliver modern user-facing applications with React, Next.js, TypeScript, and JavaScript. I enjoy collaborating with cross-functional teams, mentoring engineers, conducting code reviews, and turning complex requirements into practical, production-ready software products.

Career history

Senior Software Engineer Thoughtworks

Architect production AI-agent services using Python, FastAPI, LangChain, and LangGraph. Built agent workflows with tool calling, retrieval, conditional routing, retries, checkpoints, human approval, state management, and memory capabilities.

Designed commercial LLM integrations, RAG pipelines, and event-driven AI processing with PostgreSQL, Redis, Kafka, Node.js, Java, and Go. Delivered React, Next.js, and TypeScript interfaces, implemented OAuth2/JWT controls and observability, and mentored engineers on AI-agent and LLM development.

Senior Software Engineer Cera

Productionized LLM and machine-learning features for healthcare workflows using Python, FastAPI, PyTorch, scikit-learn, Hugging Face, and LangChain. Architected document-processing and RAG pipelines for metadata extraction, semantic retrieval, vector search, and provider search.

Partnered with data scientists to move experimental models into maintainable production services. Built ETL and feature pipelines with Pandas, NumPy, Spark, and SQL, and deployed reliable AWS-based services using SageMaker, EC2, Lambda, S3, Kubernetes, Terraform, Prometheus, Grafana, and ELK.

Senior Software Engineer Seargin

Trained, evaluated, and integrated machine-learning models for classification and prediction features in customer-facing products. Designed microservices, caching layers, asynchronous workflows, and validated, monitored APIs for ML inference.

Built full-stack applications with React, Next.js, TypeScript, Node.js, and Python using REST, GraphQL, PostgreSQL, MongoDB, and Redis. Deployed containerized AWS services with Docker, Kubernetes, Linux, and CI/CD, while improving quality and performance through Jest, Cypress, Playwright, database optimization, and frontend/backend tuning.
