I thoroughly analyze the technical assignment or task, seeking clarification for any ambiguous aspects. For larger assignments, I break them down into tasks and further into subtasks. 🔹𝙎𝙤𝙡𝙪𝙩𝙞𝙤𝙣 𝘿𝙚𝙨𝙞𝙜𝙣. I devise an implementation plan, creating a new git repository or cloning an existing one. Each task has its own branch. If time allows or if the task requires it, I write tests. 🔹𝙄𝙢𝙥𝙡𝙚𝙢𝙚𝙣𝙩𝙖𝙩𝙞𝙤𝙣. I start by developing a minimum viable prototype and then proceed with refactoring. I ensure that the code meets the specified requirements, such as speed or database query optimization. If needed, I perform additional refactoring. Once complete, I run the tests and either merge the changes to the main branch or create a pull request if I lack repository admin privileges. 🔹𝙏𝙚𝙨𝙩𝙞𝙣𝙜. Depending on the pipeline in use, the changes are typically transferred from the development branch to the test branch, where QA engineers evaluate them. If everything is satisfactory, I create a controlled backup of the production environment and introduce the new version. ✅ 𝗪𝗛𝗬 𝗖𝗛𝗢𝗢𝗦𝗘 𝗠𝗘? ✔ Extensive experience developing scalable web applications across diverse industries. ✔ Expertise in Python, Django, and Databases. ✔ In-depth understanding of industry-specific challenges and solutions. ✔ Proven ability to tackle complex technical problems effectively. ✔ Proficient in utilizing AWS, Google Cloud, and Microsoft Azure cloud-based services. ✔ Committed to delivering exceptional results and ensuring client satisfaction. ✔ Strong advocate for open and transparent communication. ✔ Efficient project management skills, ensuring timely delivery. ✔ Reliable and skilled partner dedicated to bringing your vision to life. 🛠 𝗦𝗞𝗜𝗟𝗟𝗦 🔸𝗖𝗼𝗿𝗲.
