About

I am a quick learner, self-motivated, and talented individual with a passion for building innovative products and solving complex problems. With 5+ years of experience designing, scaling, and maintaining high-performance API systems, distributed backend services, and automated workflows. I specialise in Python (Django, Django REST Framework, FastAPI, Flask), relational databases, asynchronous task queues, performance optimisation, and modern frontend stacks (React + TypeScript). I have delivered reliable backend solutions across trading systems, subscription platforms, and internal tools, with a strong focus on clean architecture, TDD (Pytest, unittest), code quality (Flake8, CI/CD pipelines), and measurable improvements in speed, throughput, and system reliability. I work comfortably in Agile/Scrum teams and as an independent contributor, collaborating with cross-functional stakeholders to deliver stable, well-tested, and maintainable software. My current project, ThirdEngineer, applies LLMs, LangGraph, LangChain, and real-time monitoring to automate issue detection and remediation for engineering teams. I am disciplined by building systems that scale, improving performance, and contributing to long-term product quality.
