DevTechStudio LLC, Remote (IT)

•Architected distributed SaaS platform using FastAPI, Django, and microservices patterns, establishing clean service boundaries and scalable
server-side systems across cross-functional engineering teams.
•Designed React and Next.js frontend applications with SSR, SSG, and ISR rendering strategies, delivering performant and SEO-optimised SaaS
platform interfaces consuming GraphQL and REST APIs.
•Built event-driven microservices using Kafka, RabbitMQ, and WebSockets on Kubernetes, improving SaaS platform resilience and enabling realtime communications across distributed system workstreams.
•Integrated LLM workflows using LangChain, LangGraph, and OpenAI API into SaaS platform features, enabling AI-assisted document processing
and agentic automation at production throughput.
•Deployed containerised Python services on AWS ECS and Kubernetes with Terraform and GitHub Actions CI/CD, reducing environment drift and
supporting repeatable SaaS platform production releases.
•Implemented Celery-based async task processing with Redis queuing, improving SaaS platform billing system throughput and decoupling
background workloads from synchronous API response cycles.
•Established pytest and Playwright testing standards with automated CI/CD coverage enforcement, raising test quality and reducing postdeployment defect rates on critical SaaS platform workflows.
•Mentored mid-level engineers through architecture walkthroughs, code reviews, and AI-native workflow sessions using Cursor AI IDE and Claude Code tooling across SaaS platform delivery teams.
•Collaborated with product and operations stakeholders using Agile/Scrum ceremonies, translating greenfield SaaS platform requirements into phased delivery milestones with clear end-to-end ownership.
