Ms Jennifer Blake
Head of Engineering
Atlassian
Level 29, 363 George Street
Sydney, NSW 2000
Dear Jennifer,
When I discovered that Atlassian is seeking a Python Programmer to build scalable backend services and data pipelines supporting millions of users globally, I recognized this was precisely the opportunity I’ve been working toward. As someone who developed Python solutions at Canva—building 8 microservices processing 2.5M+ daily transactions achieving 99.97% uptime, optimizing data processing pipelines reducing execution time by 68% from 4 hours to 78 minutes through parallel processing and algorithm improvements, and implementing automated testing frameworks increasing code coverage from 45% to 92% while reducing production bugs by 54%—I’m thrilled at the prospect of combining technical excellence and scalable architecture for Australia’s leading collaboration software company.
Over the past five years as a Python Programmer working throughout Sydney’s fintech, SaaS, and e-commerce sectors, I’ve repeatedly delivered results that match perfectly with your needs. I’ve developed robust backend systems using Python, Django, and Flask building RESTful APIs, microservices architectures, and data processing pipelines serving high-volume production environments, implemented database solutions using PostgreSQL, MongoDB, and Redis optimizing queries, designing efficient schemas, and managing data migrations, built automated testing suites using pytest, unittest, and Selenium achieving comprehensive coverage and continuous integration through Jenkins and GitHub Actions, optimized application performance through profiling, caching strategies, and algorithm improvements reducing response times and resource consumption, collaborated with cross-functional teams including frontend developers, data scientists, and product managers using Agile methodologies and code review practices, and maintained production systems through monitoring, debugging, and incident response using tools like DataDog, Sentry, and ELK stack. My background spanning payment processing, content management, and analytics platforms has shown me that exceptional Python programming merges clean code with business impact—precisely what you require for scalable, maintainable systems and product innovation.
What really attracts me to Atlassian is your commitment to engineering excellence and your investment in open-source contributions and technical community leadership. I’m proficient with Python 3.x ecosystem including Django, FastAPI, Flask, Celery for asynchronous tasks, NumPy and Pandas for data processing, and SQLAlchemy for database ORM. I’m experienced with containerization using Docker and Kubernetes, familiar with AWS services including Lambda, S3, and RDS, and knowledgeable about software design patterns, clean code principles, and SOLID architecture. I hold a Bachelor of Computer Science from UNSW, contribute to open-source projects including 15+ merged pull requests to Django and FastAPI repositories, and completed professional development in distributed systems design and Python performance optimization. One achievement I’m particularly proud of is architecting a real-time data pipeline processing clickstream events from 500K+ daily users, which used Kafka, Python consumers, and batch processing to deliver analytics dashboards with sub-5-minute latency, enabling product teams to make data-driven decisions that increased user engagement by 23%. I’m convinced that Python programmers aren’t merely code writers translating requirements—we’re problem solvers who build elegant solutions to complex challenges, quality advocates who write maintainable code that scales, and technical collaborators who bridge engineering with business outcomes delivering systems that power modern digital experiences.
I’d welcome the chance to discuss how my proven ability to build high-performance Python applications while maintaining code quality and collaborating with teams can enhance Atlassian’s engineering capabilities and product development. I can provide my GitHub portfolio showcasing production-ready code and system design examples. Thank you for reviewing my application, and I look forward to connecting with you soon.
Kind regards,
Alex Chen
