Searching Django developer who can start today (Real-Time CCTV Video Processing System)
Rating is 5 out of 5.
Jun 14, 2022 - Feb 26, 2024
Developed a system to capture and process video feeds from multiple CCTV cameras in real-time. Using a Raspberry Pi as the local processing unit, I employed FFmpeg to segment the video into 1-minute chunks. Integrated a pre-trained MobileNet SSD model for object detection and used the face_recognition library for identifying known human faces, along with custom template matching for recognizing specific cats. Set up Google Pub/Sub for asynchronous messaging and developed Google Cloud Functions to handle video processing and uploading to Google Cloud Storage. Designed a data processing pipeline using Apache Beam, deployed on Google Cloud Dataflow, and implemented comprehensive monitoring and logging with Google Cloud Monitoring to ensure system scalability and reliability.

"Aldian is one of the best Google Maps API devs I worked with. And thats coming from someone who's worked with a lot of developers on oDesk. He understood the problem at hand with little direction and took the project to a fruitful completion. Not old did he follow the spec, but also suggested and implemented nice improvements. The code he submitted was always bug free, which you would understand the importance of, if you ever hired on oDesk. In short, I wouldn't hesitate twice for hiring Aldian an a future project."
