What projects have you completed in your programming career?

i have made major projects and many minor assignments during my studies.

the very first big project that i made was a library database and transaction system during my school, for the o-levels computer studies project. it was fully functional and was made on microsoft access.

the next big project was also a library database during my second semester in the college and i implemented that using C++. we managed the database but we weren't able to complete the transaction portion of the program.

recently i made a simulation project relating to analog systems where i simulated a pulse code modulator and demodulator system and also a DSB-SC modulator with demodulation through Costa's loop. all this was done in simulink and was relatively easy compared to other projects.

but the best of all is the fingerprint matcher that me and my friend implemented in MATLAB. it found out the minutiae points on a fingerprint image and related it to other saved images in the database and returned the percentage match with the other fingerprints, we kept the threshold of 70% to return a positive match. the best thing about this algorithm was that you could input the image of the finger print at any angle and it returned satisfactory results no matter what.

I have made a minor project on ONLINE EXAM AND E-LEARNING...
This project was made in JAVA lang. ...
Database was in Microsoft Access....
