I am a software engineer with 4 years of experience spanning backend development, DevOps, and cloud platform engineering. I build scalable, secure, and automated cloud platforms from the ground up and bring a developer-first mindset to every infrastructure challenge I take on. I work well independently and communicate clearly throughout every engagement, from scoping to delivery. BACKGROUND My career started in software development, building production applications using Spring Boot and Python. This backend foundation shapes how I approach cloud and DevOps work, because I understand what developers need from the platforms they run on. I have hands-on experience with modern AI/LLM tooling including LangChain, LangGraph, and LiteLLM, and I have integrated vector databases like OpenSearch into production systems. This means I can support teams building AI-powered products at both the application and infrastructure layer. WHAT I CAN DO FOR YOU Whether you are a startup building your first cloud environment or an established team dealing with scaling, reliability, or cost problems, I can step in at any stage of the process. * Design and build cloud infrastructure on AWS or GCP from scratch * Migrate existing workloads to the cloud with minimal downtime * Build and maintain backend services and REST APIs using Python or Java * Design relational and non-relational database schemas and optimize query performance * Containerize applications using Docker and orchestrate them with Kubernetes * Build or improve CI/CD pipelines using GitHub Actions or Jenkins * Implement GitOps workflows with ArgoCD for automated, auditable deployments * Write clean, reusable Terraform modules for reproducible infrastructure * Set up full observability with Prometheus, Grafana, and Loki so your team has visibility into everything * Harden your cloud environment for security and compliance * Optimize infrastructure costs without sacrificing performance or reliability * Integrate LLM tooling and AI components into cloud-native architectures CORE SKILLS Backend Engineering * Python, Java, Spring Boot * REST API design and development * PostgreSQL, MySQL, MongoDB, Redis * Message brokers: Kafka, RabbitMQ * Microservices architecture and system design * Authentication and authorization: OAuth2, JWT, Keycloak * Unit testing, integration testing, test-driven development DevOps & Platform Engineering * Kubernetes, Docker, Docker Compose * GitHub Actions, Jenkins, ArgoCD * Terraform, Linux, Bash scripting * Prometheus, Grafana, Loki AI & LLM Engineering * LangChain, LangGraph, LiteLLM * OpenSearch and vector database integration * RAG pipelines and LLM application development Cloud Platforms * AWS: End-to-end architecture, migrations, and optimization * GCP: Production-grade platform design and deployment CERTIFICATIONS Google Cloud * Google Cloud Professional Cloud Architect AWS (13 Certifications) Foundational * AWS Certified Cloud Practitioner * AWS Certified AI Practitioner Associate * AWS Certified Solutions Architect - Associate * AWS Certified Developer - Associate * AWS Certified SysOps Administrator - Associate * AWS Certified Data Engineer - Associate * AWS Certified Machine Learning - Associate Professional * AWS Certified Solutions Architect - Professional * AWS Certified DevOps Engineer - Professional * AWS Certified Generative AI Developer - Professional Specialty * AWS Certified Security - Specialty * AWS Certified Advanced Networking - Specialty * AWS Certified Machine Learning - Specialty HOW I WORK I treat every client engagement like a product. That means understanding the business context behind the technical requirement, communicating progress clearly, delivering clean and documented work, and making sure what I build can be maintained and extended after I am done. I do not disappear after delivery. I make sure things work. I am available for both short-term engagements and longer-term platform work. If you have a specific problem to solve or a platform to build, send me a message and we can determine if I am the right fit.
