C 编程 Jobs

C Programming is a powerful, high-level and highly structured programming language used to develop a range of applications, including operating systems, processing intensive computations and embedded systems. The language is designed to create a network of instructions that tells a computer what to do and how to do it. C Programmers are highly skilled software developers who understand how to turn lines of code into working programs that can solve a wide variety of challenges.

With their deep knowledge of the language, C programmers have an arsenal of tools at their disposal.

  • Writing software for a range of robotic applications
  • Creating advanced websites and mobile applications with secure authentication systems
  • Enhancing image processing techniques with sophisticated algorithms
  • Streamlining hardware communication protocols with custom implementations
  • Simplifying communication between hardware components with protocol decoders
  • Developing sophisticated animation features for post production workflows

    We would like to develop a program to automatically build a chronology from a large set of emails (say, 1000+). We typically receive a PST file of emails from our clients. We regularly work with an electronic discovery platform called Goldfynch to convert those emails into an indexed set of PDF documents. As part of that indexed set, we have a CSV file listing each email and attachment, and a corresponding text file containing the full text of the email (including the email header and body). We would like to take that a step further and develop a program that automatically builds a chronology in Excel (or a CSV file) from the body text from that set of emails. For example, if John Smith sent an email to Adam Shore on May 15, 2023 at 2:33 PM writing: "Sure, pizza works", the ou...
