Professional Summary
I’m a dedicated Python & Rust developer with over X years of hands-on experience designing, building and maintaining web applications and APIs. I partner closely with clients to translate business requirements into clean, well-documented, production-ready code—whether it’s a high-traffic microservices architecture or a lean MVP prototype. My end-to-end expertise spans back-end, front-end, DevOps and QA, ensuring rapid delivery without ever compromising on quality or scalability.
? Core Competencies
1. Python Web Development
  • Frameworks: Django (ORM, Admin, Channels), Flask (Blueprints, Extensions)
  • Architecture: Monoliths, Microservices, Service-Oriented designs
  • Performance: Caching strategies (Redis, Memcached), async tasks with Celery and FastStream
2. API Design & Implementation
  • Python APIs: Django REST Framework, Flask-RESTPlus, FastAPI (async, dependency injection)
  • Rust APIs: Axum, Actix, Ntex—leveraging Rust’s memory safety and performance for ultra-fast endpoints
  • Standards & Best Practices: OpenAPI/Swagger docs, JWT/OAuth2 authentication, rate limiting, versioning
3. DevOps & Cloud Infrastructure
  • Cloud Providers: AWS (EC2, Lambda, RDS, S3, CloudFormation), GCP (Compute Engine, Cloud Run, Firestore)
  • Infrastructure as Code: Terraform, AWS CDK
  • CI/CD Pipelines: GitHub Actions, GitLab CI/CD, Jenkins—automating build, test and deploy workflows
  • Monitoring & Logging: Prometheus, Grafana, ELK stack
4. Containerization & Orchestration
  • Containers: Docker (multi-stage builds, best practices)
  • Orchestration: Kubernetes (Helm charts, StatefulSets, RBAC), Docker Swarm
  • Service Mesh / Networking: Istio, Envoy for advanced traffic management
5. Front-End Integration
  • Libraries & Frameworks: Vue.js (Vuex, Composition API), Svelte, TypeScript
  • Bundlers & Tooling: Vite, Webpack, ESLint/Prettier
  • Responsive UIs: Mobile-first designs, component-driven architecture
6. Database Management
  • Relational: PostgreSQL, MySQL (query optimization, migrations)
  • NoSQL: MongoDB, Redis, Elasticsearch
  • ORMs & Query Builders: SQLAlchemy, Django ORM, Diesel (Rust)
7. Quality Assurance & Testing
  • Test-Driven Development: Pytest, unittest, Rust’s built-in test framework
  • Coverage & Linting: Coverage.py, flake8, clippy (Rust)
  • Load & Performance Testing: Locust, k6

? Why Work With Me?
  • Clear Communication: Regular updates, open backlog in Trello/Jira, video demos
  • Robust Documentation: Auto-generated API specs, README guides, in-code comments
  • Agile Mindset: Sprint planning, iterative delivery, flexible reprioritization
  • Long-Term Partnership: Post-launch support, performance tuning, feature roadmaps

Whether you’re launching a startup MVP, refactoring a legacy system, or scaling to millions of users, I’ll bring the technical depth and collaborative spirit to make your project a success. Let’s discuss your next challenge!
