Advanced Git: Rebase, Recovery & Branching Strategies
Go beyond the basics: interactive rebase for history sculpting, cherry-pick extraction, deep 3-way merge conflict resolution, reflog disaster recovery, annotated tags for releases, git bisect for regression hunting, worktrees for parallel development, and GitFlow vs trunk-based branching strategies.

Become the Engineer Who Supervises AI
As AI generates more code, understanding what that code does becomes more valuable, not less. Someone must verify AI output, debug failures, and make architectural decisions.
Build Your Architectural EdgeYou run Git commands every day without seeing what they do to your commit graph.
The gap between knowing commands and understanding Git
You've run git rebase -i and hoped nothing broke.
You've lost commits to a git reset --hard with no idea
how to get them back. You've stared at merge conflicts, guessing
which side to keep because you couldn't identify the merge base. AI
suggests Git commands too, and you accept them because the
alternative is decoding man pages for half an hour. Every one of
these moments comes down to the same root cause: you can't see what
Git does to parent pointers, hashes, and branch references when a
command runs. Without that visibility, you can't predict outcomes or
recover when things break.
See Git's invisible mechanics in real-time
Interactive simulations that make commit graph operations visible and predictable.
Watch rebases rewrite history
Step through an interactive rebase and see parent pointers change, new cryptographic hashes generate, and old commits become unreachable on a visual commit graph.
Trace recovery paths through the reflog
Follow chronological HEAD movements, see how orphaned commits remain accessible through reflog entries, and practice restoring lost work after hard resets and deleted branches.
Step through binary search debugging
Watch git bisect narrow a regression to one
commit, seeing each midpoint checkout and how the algorithm
eliminates half the remaining history at every step.
What's Covered
Eight lessons covering history rewriting, conflict resolution, disaster recovery, debugging, and team branching architecture.
Rewrite, reorder, squash, and cherry-pick commits to shape a clean, intentional timeline before sharing your work with the team.
Understand 3-way merge algorithms, identify the merge base in criss-cross topologies, and resolve multi-file architectural conflicts using diff3 format.
Recover orphaned commits through the reflog after hard
resets, deleted branches, and botched rebases. Isolate
regression bugs to a single commit with
git bisect.
Choose between GitFlow and Trunk-Based Development for your
team, manage releases with annotated tags and SemVer, and
run parallel workstreams using git worktree.
The Curriculum
Comprehensive Lessons! Each with theory, interactive simulation, and quiz.
Interactive Rebase: Sculpting Local History
The git rebase -i interface and its
interactive todo list. Squash minor fixes, reword commit
messages, and reorder history before sharing. See how
rewriting commits generates new cryptographic hashes and
rewrites parent pointers across the modified chain.
Surgical Extraction: Git Cherry-Pick
Isolate and extract specific commits from divergent
branches using git cherry-pick. Target
commits by hash, understand how diff patches are
duplicated and applied onto your current HEAD, and
resolve conflicts when the target branch lacks the
necessary foundational context.
Deep Dive: 3-Way Merges and Complex Conflicts
The mechanics of 3-way merge resolution. Identify the closest common ancestor (merge base), navigate criss-cross topological histories, interpret diff3 format output, and safely integrate divergent multi-file architectural changes.
Disaster Recovery and the Git Reflog
The reflog as Git's local, time-stamped journal of every HEAD movement. Track chronological pointer changes, recover unreachable commits lost to accidental hard resets, deleted branches, or botched rebases, and decode reflog syntax to restore orphaned data.
Release Management with Annotated Tags
Lightweight tags (simple pointers) versus annotated tags (full Git objects with author metadata, dates, and cryptographic signatures). Attach tags, push them to remotes, trigger CI/CD pipelines from tag events, and integrate Semantic Versioning (SemVer) into your project graph.
Archaeological Debugging: Git Bisect
Automate regression bug hunting with
git bisect. Define good and bad endpoints,
let binary search check out midpoint commits
automatically, and isolate the exact cryptographic
snapshot that introduced a bug with mathematical
efficiency.
Parallel Architecture: Git Worktrees
Check out multiple branches simultaneously into separate
physical directories using git worktree.
Understand how a shared .git folder powers
isolated working trees, and manage the full lifecycle of
linked worktrees from creation to cleanup.
Branching Strategies: Trunk-Based vs. GitFlow
Compare GitFlow's long-lived branches (feature, develop, release, main) with Trunk-Based Development's short-lived feature branches and feature flags. Understand the mechanics, tradeoffs, and team dynamics behind each workflow architecture.
Git confidence built on seeing what actually happens
After this Deep Dive, you'll rebase local history, recover orphaned commits, resolve complex merge conflicts, and architect team branching strategies with full visibility into what Git does to your commit graph at every step. You become the engineer your team calls when the history breaks.
