Developers who know C and operating-system basics and want to write correct, fast network software, understand what happens on the wire, and diagnose performance problems like a systems engineer.
Expert level
Systems and Networks
Network Programming and Systems Performance Engineering
Build network servers from sockets up and understand them under load: TCP and TLS behaviour, event-driven servers with epoll, a safe HTTP implementation, performance methodology with profilers and tracing, and a measured, hardened network service.

At a glance
C programming, processes, threads and file descriptors on Linux (see Operating Systems in Practice), basic networking vocabulary (IP address, port, DNS) and a Linux environment where you may run tcpdump, tc and perf (a virtual machine or a cloud VM is ideal). Root access in a disposable machine is needed for some exercises.
Pass the quizzes and labs, then submit a capstone project. The NIBVEDA team reviews it and either accepts it or sends it back with comments you can act on.
What you will be able to do
- 01Write correct TCP clients and servers, handling partial reads, framing and errors
- 02Design event-driven servers with non-blocking I/O and epoll and compare concurrency models with measurements
- 03Explain TCP behaviour (windows, congestion, retransmission) and observe it with packet captures
- 04Implement a safe HTTP/1.1 parser and server and inspect TLS connections
- 05Find and remove bottlenecks with perf, flame graphs, strace and queueing reasoning

What you take away
An internship certificate with your skills on it.
Made for you automatically when you finish the last part, it names the internship programme, the level and the 40 hours, lists what you showed, and carries a number and a QR code. Anyone can check it on the NIBVEDA verification page, and it shows as withdrawn there if it is ever revoked.
- Proof you completed all 40 hours of this internship programme
- An Internship badge for your profile, CV or portfolio
- Not a job, a stipend or an academic degree, and it says so
Keep building.
3 programmes in this track, from beginner to expert. Buy the learning path and save 15%.
Learn how an operating system works by using and building its pieces on Linux: processes and system calls, scheduling and threads, synchronisation, virtual memory, file systems and container isolation, with code and measurements.
- System calls
- Processes and threads
- Synchronisation
Learn C and how a computer really works: memory, pointers, bits and bytes, files, debugging with real tools and writing safe code, finishing with a command-line tool suite of your own.

Is this a real internship?
It is a virtual internship programme: a structured, self-paced course built around a real project, with checked assessments and a certificate. It is not employment, it does not carry a stipend and it is not an academic or AICTE-approved qualification. What it gives you is verified, project-based evidence of skills.
How does self-paced work?
You start when you like and move at your own speed. Each part unlocks when you finish the one before it. There are no live classes and no deadlines. Your access is shown on each programme page.
How is my work checked?
Quizzes are marked as soon as you submit them. Labs use a tick-list of tasks. Intermediate and Expert programmes finish with a capstone that the NIBVEDA team reviews and either accepts or sends back with comments.
Can I get a refund?
