Performance Engineering
Core Web Vitals & Optimization
I don't just build fast apps — I instrument, measure, and surgically optimize every millisecond. Real scores. Real impact.
0 Lighthouse
Consistently 100 Across All Metrics
From code-splitting and lazy-loading to font subsetting, HTTP/3, and edge caching — every optimization is deliberate and measured with Lighthouse CI, WebPageTest, and real RUM data.

Key Algorithm Patterns & When I Use Them
🪟
Sliding Window
Max subarray sum, longest substring without repeats, minimum window substring — O(n) solutions replacing O(n²).
ArraysStrings
🔱
Two Pointers
3Sum, trapping rain water, container with most water — collapses a nested loop into a single linear pass.
ArraysSorting
🌳
DFS / BFS
Graph traversal, island counting, word ladder, shortest path in unweighted graphs — the backbone of tree/graph problems.
GraphsTrees
📈
Dynamic Programming
Knapsack, longest common subsequence, coin change, edit distance — memoisation and tabulation from scratch.
OptimisationCounting
🔍
Binary Search
Search in rotated arrays, kth smallest element, capacity problems — apply on answer space, not just sorted arrays.
ArraysMath
↩️
Backtracking
Permutations, subsets, N-Queens, sudoku solver — prune early, build incrementally, never over-allocate state.
CombinatoricsRecursion
🔗
Union Find
Number of connected components, redundant connection, accounts merge — path compression + union by rank for near-O(1).
GraphsSets
⛰️
Monotonic Stack
Next greater element, largest rectangle in histogram, daily temperatures — O(n) solutions via invariant maintenance.
