Skills — what Ahsan Mahmood works with, and how deeply
Twenty-six tools across five groups, each with a stated depth and the year it entered the stack. No percentages, because nobody measured one. Read the matrix by group or by level.

The list is maintained in the admin panel. Nothing has been added to it, so nothing is claimed here.

The request timed out. Nothing was changed — your filters are still set.
Could not load the skill list
- Everything
- Filter skills by group
Never shipped, never studied seriously. There is no rung on this ladder low enough to make listing it honest.
- Blockchain and smart contracts
Five course completions exist and they are on the CV, framed as what they are. They are not accreditations, so they do not raise a rung on this page.
- A count of certifications
Design systems are on the list because I build and maintain them in code. Brand identity, illustration and art direction are not the same job and I do not take them.
- Visual design as a deliverable
There is no Apple Developer account behind this work, so nothing has ever shipped to the App Store. Android and the web are where the store listings actually are.
It is real inside the Perkforce role and it stays on the CV there. It is not part of what I lead with any more, so it is not on this list dressed up as current.
What is deliberately absent
A skills page that lists only strengths is a sales page. These are the gaps worth knowing before you scope anything with me.
Every tool below carries two things I can defend: a depth I chose in plain English, and the year it entered my stack. Read the matrix down a column to see where I am strongest, or across a row to see what I bring to one kind of problem.
- Read the matrix
- What the depths mean
Grouped by where it sits in a stack, ordered the way I reach for it.
- Read this before the matrix
Three words, each defined against something checkable
If a definition does not match what you need, say so on a call. I would rather lose the work than have you find out in week three that “Working” meant what it says.
- Every skill, by category and by depth
- Group
The capability matrix
Depths are a claim. The products are the proof — every one of them shipped, most of them still running. Go and open a few, then tell me what you need building.
A list is not evidence
Nothing is left after that filter. Clear it and start again.
Nothing matches that
The number that is not here
A depth is a category, so it is shown as one — a position in a matrix, not a length. A year is a number, so it is shown on a timeline, where length means elapsed time and nothing else.
- Never
- A percentage, a score, or a five-star rating
- Stated
- Depth, in one of three words
- The year it entered the stack
This page used to say React 95%. Nobody measured that. It came from a lookup table that turned the word “expert” into a number so a progress bar would have something to fill.
Years of production work, including the parts that break.
I have debugged this under deadline pressure, know what it is bad at, and would argue with its documentation. If a project lives or dies on it, I do not need a second pair of hands.
Shipped with it across more than one project, by design rather than by tutorial.
I can choose the right shape up front instead of discovering it in review. I still reach for the documentation on the unusual paths, and I say so rather than guessing.
Real shipped use, and a shallower floor than the two above it.
It has done a job in production. I would still want review on anything load-bearing, and I would tell you that before quoting rather than after.
- Search skills by tool name
- The other honest number
When each one entered the stack
Years are a real quantity, so they get the encoding a real quantity deserves. Nothing leaves this list once it is on it — a tool I have stopped reaching for is recorded on the CV, not quietly deleted from here.
