Contribution Heatmap
Hover or focus any cell to see what was actually happening career-wise. Milestone highlights are real; day-to-day density is illustrative since LinkedIn has no commit-level data.
Career Journey
Scroll down to walk the road — on desktop the journey scrolls horizontally as you scroll the page; on mobile, swipe the road directly.
Skills Dashboard
Levels are a transparent heuristic, not an official rating: Expert = LinkedIn "Top Skills", Advanced = named in Core Expertise, Working = mentioned in a single role/project.

Note: LinkedIn lists 28 skills total but only surfaces 2 without an extra click (System Architecture, Process Automation). The categories above are compiled from the "Top skills" list and the "Core Expertise" bullets in the About section — [REVIEW: open your LinkedIn profile → Skills → "Show all 28" and tell me if anything important is missing].
Projects
17 real projects — ANGUNET plus the 16 pulled from my live portfolio, all with real screenshots. Filter by category, click any card to expand key features, architecture notes, and challenges.
Experience
Reconciled from saifulrehman.site (primary source) and LinkedIn — a few month-level dates differ slightly between the two; see PLACEHOLDERS.md for the one conflict (Solvefy) and how it was resolved.
