A freelancing developer is an independent developer hired to solve problems for clients on a short term basis.
Unlike a full time employed developer, a freelancing developer does not owe the company any long term commitment, nor does the company owe the developer any.
They are hired on a contract basis to deliver services to their clients and are paid per project or through milestone based recurring payments.
Systems fail when theyโre not built for sudden spikes.
Good architecture isnโt just about writing code. Itโs about preparing for the moment everything blows up.
Caching, load balancing and proper scaling save you when traffic gets wild.
