Backend Developer | Python Specialist | Microservices & Authentication Architecture

I'm a backend engineer with 6 years of experience designing and building production-grade systems for enterprise clients, currently working as a Technical Lead. I specialize in:

🔐 Authentication & Identity
Building centralized, scalable auth systems using Keycloak and JWT — including offline-validation strategies that keep services running through identity-provider outages, and Git-submodule packaging for shared auth logic across microservices.

⚡ Real-Time & Event-Driven Systems
Designing WebSocket-based real-time data channels and Kafka-based messaging pipelines to replace slow polling architectures, with Redis caching to cut redundant database/API calls.

🔗 Integrations & CMS
End-to-end integration work — CRM syncing (HubSpot, Salesforce), ADMS/enterprise system integrations, and building CMS platforms from scratch (Strapi) including custom migration tooling that moves entire environments (DB, media, config) in minutes instead of hours.

🛠️ Core Stack
Python (FastAPI, Django, Flask), JavaScript/TypeScript, Node.js/Express, MySQL, PostgreSQL, MongoDB, Oracle, Docker, AWS, Red Hat OpenShift, CI/CD (Jenkins, GitHub Actions, Argo CD).

🤖 AI-Accelerated Development
I actively use AI coding tools (Claude, Cursor, Copilot, ChatGPT) to speed up development, generate robust test coverage, and reduce turnaround time — without cutting corners on quality.

✅ Certifications: AWS Certified Cloud Practitioner, IBM Cloud Advocate, Confluent Certified Developer for Kafka

I'm comfortable working independently or within Agile teams, and I bring a track record of taking systems from "it works" to "it's reliable at scale." Let's talk about your project.
