I focussed on automobile electronics . Specialised in security system and programming from 2001 above almost all vehicles brands are introduced there own way to secure their customers Vehicles by implementing Immobilizer , now it's have more secure features than your smartphones . if you forgot your phone password what you do?! . if you try the all the way , you didn't get ! you whill do factory reset , but some don't come that function without unlock otherwise you need to go a authorised service centre ,it coast you to much money ! same as like phone , when you buy a car they give you atleast 2 more keys , the each keys have individual ID and frequency . like you finger print lockwhen you lost one key you can use other one , and when you loose all keys ? big issue that's the time we will healp you because it's not ordinary lock like your bedroom door . it have physical design that access the mechanical opening , but not gona start the engine , when you trun on ignition it's nedd to authenticate with your key transponder ID , if Id is not present or miss match your engine not gona start , (also keyless entry)so i specialised in this systems , becouse each manufacturers have their secured way to access the system and it's maintanence Next think is automotive PROGRAMMING it's just like keys systems but little different if have 10 computer and 5 laptops 1 printer in your office . the all systems are connected by a cable called LAN cable /wifi with a secured area network by IP address, And think one day the computer for accounts controlling got hardware damage and it stop working , this issue will be alert the server and technician will come and fix it . other wise the entire system will be collapse , when the technician replace the computer he need to synchronise the computer with the network IP and also assign it's parameters , In a car it have minimum 3 modules maximum have more than 80 . the all modules are communicating with each other by a network called CAN , and this huge data transfers is through a gateway module . and some cars have a more networks like engine have one special for more safety .on programming my job is to synchronisation of modules and it's calibration , findings which one have the problems ,The other technology is now a days the all manufacturers implement Artificial intelligence in vehicle for safetyit's comming lot of alignment , sensors ,camera and they need calibration it's called ADAS system I love my job because It's my passion every day I learn more more from each work I attended
