I'm a full time freelancer and I specialize in automation development (& general backend dev) with Python, NodeJS and occasional Shell Scripting. I also do front-end web development - you can checkout my other Specialized profile for this. I have good experience in building backend systems, fully automated workflows, etc. - local & distributed/on-the-cloud with AWS/GCP/Azure. Total Dev Experience: 14+ years Experience & Tech Stack - Backend: - Python, Node.js, Elixir, Bash Script .. some Java, PHP & PERL - REST API Development (Express.js, Flask, Django), optionally with GraphQL - Middlewares: RabbitMQ, Redis - Cloud Integrations/Deployments with AWS & GCP - Serverless Functions: AWS Lambda, Google Cloud Functions, Netlify Functions - Databases: MySQL, PostgreSQL, MongoDB, DynamoDB (with or without ORMs) - 3rd Party API Integration (Google API, Facebook API, Twilio API, etc.) - Docker Frontend: - Vue.js (Nuxt, Quasar, Gridsome) - Webpack, Sass/Scss/Less, ES6 Javascript - Serverless/JAM Stack development & end-to-end setup Automation Scripting: - PDF Parsing with PDFMiner, Tabula - Web Scraping with plain HTTP requests, Selenium, Puppeteer/Headless Chrome - High concurrency distributed automation system development with Celery, RabbitMQ & Redis .. optionally deployed with Docker - eMail/SMS/Twilio/Telegram Notifications & Integration (read/send) - Image OCR with Tesseract - Auto-Betting Workflows - Auto-Purchasing Workflows, etc. - Quick one-off shell scripts I always start with proper tasks & estimates and will be consistent with regular updates. This way there will be no surprises in cost/time and you'll be up-to-date with the progress without you having to chase around the freelancer. When delivering my code, I’ll make sure that it is well designed, professionally written to the highest quality & efficiency with solid, re-usable, following OOPS concepts, proper commenting & documenting. Future developers (if any are hired after me for maintenance/updates) can go through the code and update/refactor with ease - I know how it feels as a developer to read bad code and attempt to do anything on top of it. I also share screencasts to show the setup & execution of the code or a README file. I apply only to jobs which relies on my skill set and which I consider I can finish no matter what - implying I already have a high level mental plan on approaching/solving the problem described there. The rest I mostly leave it to the regular invites. So yeah, send me an invite to your job, we can discuss and take it forward from there. Availability and communication will never be a problem as I'm always almost available for a quick chat/call. You'll know my quality when you work with me. Looking forward to many great work experiences.
