1. Discuss the requirements with the PM, design the API, comply with the microservice architecture, and meet the 3H principle, weigh the requirements and engineering difficulties, and evaluate the development time. 2. Mainly developed using Python, which conforms to the RestFul style, and provides interfaces for other teams to connect through OpenAPI/Swagger API + files. 3.POC Some ideas put forward by PM and evaluated whether they are feasible, such as: Retrieval-Augmented Generation, RAG with open source model to make the company’s private AI (Vector DB), or connecting to the API of public generative AI through prompt, or It uses golang and k8s api to create extensions, yaml or Terraform for automated deployment. 4. Use tensorflow's forests decision prediction to obtain some information, machine learning frameworks such as tensorflow and pytorch, and also use huggingface's lib to connect multiple models (self-study of basic AI or machine learning and other related knowledge), and also study google self attention model, etc. 5. Experience in using multiple clouds, and using Terrafrom to set up cloud services, including: AWS, GCP, Azure, etc. 6. Performance optimization, experience in improving the performance of remote session log services by more than 80%. 7. Separately develop the SSO system used by the company's services, including social login or enterprise login such as google, microsoft, etc. 8.TDD or DDD practical development experience. 9. Experience in using docker, kubernetes, elasticsearch, fluentd, colima, k3s, boto3, minio, ceph, postman and other software. 10. Have extensive experience in multiple process or multiple threading. 11. Experience in using relational databases such as PostgreSQL, MSSQL, and non-relational redis. 12. Version control is mainly based on Git and Git Flow. 13.linux system operation

1. Python crawler, collect data and analyze it through big data, use tensorflow's forests decision prediction to obtain certain data, machine learning frameworks such as tensorflow and pytorch, and also use huggingface's lib to connect multiple models (self-taught basic AI or Machine learning and other related knowledge), and also researched the Google self attention model, etc. 2. C# .net core project development, discuss requirements with PM, do API design, and screen design, comply with microservice architecture, and meet the 3H principle, weigh requirements and engineering difficulties, and evaluate development time. (Full-end engineer) 3. Develop face recognition software, mainly using OpenCV. However, due to delays in other development needs and material factors, the project was abandoned. 4. Import the microservice architecture into the project architecture developed by the company, maintain the old programs and reconstruct services that conform to the new architecture. For example, change the company's email sending and receiving services to microservices, and other used projects can be unified through api for processing...and so on. 5. Define the lint format check Python language, unify the company's coding style, such as snake case, camel case, introduce education and training, solid principle explanation, sharing meetings, etc. 6. Experience in moving on-premises software services to the cloud (Azure, GCP) after reconstruction. 7. Unify the way each language connects to SQL, and create different providers through the interface layer, which can facilitate the connection of different DBs, move business logic into the code, introduce the ORM concept, and write it through the ORM method and express it with lambda The formula takes priority. 8. Connect to azure pipelines process, import and use CI/CD. 9. Database schema design (ex: regular) and performance optimization (ex: partition) also optimize queries that are easy to timeout. 10. IIS environment maintenance, various gadgets ex: win 10 work scheduler, scheduled sending, etc.

1. Sometimes I go to the client to discuss requirements, assessment time, and development with the client. 2. Full-end engineers will develop front-end through jquery, javascript and front-end template bootstrap. C# will be developed with asp.net framework. 3.IIS environment construction, installation, etc. 4.MS-SQL database schema design (ex: regular) and performance optimization (ex: partition).

1. API connection, writing code that conforms to the restful style. 2. Document the API response and define the specifications of the model. 3. Develop your own development and testing tools (I didn’t know there was swagger ui at that time), send request testing through postman, and develop/debug on your own UI.
