Expertise in building backend services and APIs using Python frameworks such as FastAPI, Django and Flask. Proficiency with SQLAlchemy, psycopg, Alembic, Celery, REST and GraphQL APIs, integrations and data processing workflows.

AI & Automation
Hands-on experience with retrieval-augmented generation, Qdrant vector databases, local vLLM serving, embedding-provider abstractions, BGE-M3, MCP, Rasa, DialogFlow, spaCy and NLTK for building privacy-focused AI and NLP-enabled solutions.

Architecture & Performance
Design and delivery of modular, scalable cloud-native systems using backend-for-frontend patterns, Keycloak/OIDC, Kafka, RabbitMQ, Redis, API lifecycle design, database optimization, Docker and Kubernetes.

Data Platforms
Experience with PostgreSQL, MySQL, MongoDB, Redis, Qdrant, Neo4j, Elasticsearch, Oracle/PLSQL and solar-inverter data pipelines for diverse data storage and retrieval needs.

Quality & Delivery
Testing and quality assurance using Pytest, Vitest, React Testing Library, JUnit, Jest and Snaptest; migration-chain verification, SQL compatibility guards, Docker, Kubernetes and CI/CD pipelines.

Supporting Engineering
Supporting full-stack delivery with Java using Spring, Spring Boot and Quarkus; frontend development with React, TypeScript, Vite, Tailwind and Capacitor for end-to-end application delivery.
