20 free backend courses
A curated list of 20 free backend courses covering Git, Node.js, Docker, Kubernetes, Kafka, Redis and more is circulating — a practical resource for building the infra skills top Bay Area teams expect. The thread is framed as a fast path to the skillset earners command for $170K+ roles. (x.com; x.com)
The X thread points readers to public course-aggregation repositories on GitHub, including the long-running free-courses collection by alinebastos and a hands‑on "Free 6‑Weekends NodeJS Backend Development Course" repo that lays out week-by-week modules. (github.com/alinebastos/free-courses; github.com/OkekeChristian24/Free-6-weekends-nodejs-backend-development-course) Major MOOC platforms cited in similar lists still separate free content from paid credentials: edX’s audit track excludes graded assessments and verified certificates, and verified certificates commonly cost roughly $50–$300 on that platform. (help.edx.org/edxlearner/s/article/What-are-the-differences-between-audit-free-and-verified-paid-courses; upskillwise.com/edx-pricing) Coursera likewise offers audit/preview access to many courses but requires payment or financial-aid to submit graded work and obtain course certificates, so "free" collections often point to audit‑only learning rather than credentialed completion. (classcentral.com/report/coursera-free-online-courses) The thread’s $170K+ salary framing is consistent with Bay Area compensation data: Levels.fyi reports a median Backend Software Engineer total compensation of about $246,875 in the San Francisco Bay Area, while Salary.com lists an average backend base of roughly $164,470 for San Francisco. (levels.fyi/t/software-engineer/title/backend-software-engineer/locations/san-francisco-bay-area; salary.com/research/salary/listing/backend-software-engineer-salary/san-francisco-ca) Current Bay Area job listings and hiring pages emphasize system‑design, production deployment and distributed‑systems experience for mid/senior backend roles, and public job ads show wide salary bands (examples in the $119K–$250K range depending on level and company). (indeed.com/q-Backend-Developer-l-San-Francisco-Bay-Area,CA-jobs.html; builtin.com/job/software-engineer-i-backend/4349548) Some aggregated free resources include project-based labs and playlists—freeCodeCamp and several GitHub learning-path repos provide multi‑hour projects and playlists—while other lists are primarily link collections without integrated mock interviews or system‑design walkthroughs.
