One year ago, on January 1st, 2024,
I made a promise to commit to coding every day by starting the #100DaysOfCode challenge.
It was tough 💪, but also incredibly interesting and exciting ✨️
Completing this challenge was absolutely worth it 💯
Winter Arc Day 29:
Building a VDOM Duffer! 🧠⚙️
React isn't reactive; it's scheduled. Today, I implemented diffVNodes to manually compare old and new virtual nodes.
Tests passed. Core concept understood.
Mentally locked in.
#React #JavaScript #SoftwareEngineer
Day 28: Into the matrix with Dynamic Programming. 🧠
Completed the 100 Club,
hit hydration,
and tackled DP concepts + problems in VS Code.
Tests Passed.
Winter Arc continues. 🔥❄️
#WinterArc #DynamicProgramming #100DaysOfCode #BuildInPublic
Day 27 of the Winter Arc ⚡️
Mastering decision trees and state restoration: Heaps, custom sorting, and Backtracking (subsets & top-k elements).
Choose, explore, un-choose.
All tests passed cleanly.
🌅 05:10 AM | 💧 2L | 🏋️♂️ 100 Club
#WinterArc #TypeScript #Coding
Day 26 of the Winter Arc ⚡️
Locked in on Graph Algorithms: BFS, DFS, and Topological Sort. From resolving dependency chains to package managers—tests passed.
🌅 06:00 AM | 💧 2L | 🏋️♂️ 100 Club | 💻 Graph Traversals
#WinterArc #TypeScript
Winter Arc Day 25. ❄️
Mastering tree structures and traversals (DFS/BFS) today.
Wake: 07:00 AM
Hydration: 2.0L
Physical: 100 Club (Pushups/Situps/Squats)
Steps: 18,099
Code: All tests passed
Locking in. ♟️
Winter Arc Day 24:
Linked Lists, Stacks & LRU Cache
Paired a Hash Map with a Doubly Linked List to build an LRU Cache with O(1) get and put operations.
All test suites passing.
Pointers and stacks form the bedrock of memory allocators and high-speed in-memory caches.
Day 23 of the winter arc,
late start but a strong finish.
Hydration goals met,
locked in for the physical challenge (100 club),
and crushed the deep work.
Today's focus: Sliding Window & Substring Algorithms.
Winter Arc Day 22 ❄️:
Feeling stronger today,
so I doubled up and hit 20 reps
in one of my sets instead of 10.
Also locked in on some Two Pointers & Complexity Analysis in TS.
All tests passing, we love to see it. ✅
Keep showing up.
Day 21 of the Winter Arc ⚔️💻
Finished Week 3 with a heavy hitter:
Building a Type-Safe RPC Client from scratch using TypeScript generics and Zod validation.
🏋️♂️ Physical Lock-In: 300 total reps (100 pushups, 100 situps, 100 squats) + 2.0L hydration.
#WinterArc
Winter Arc — Day 20 🖤
💻 Today's focus: TypeScript + Zod
• Defined runtime validation schemas
• Inferred TS types from schemas
• Ran tests — all passing ✅
Static types are great, but external data still needs runtime validation.

Surgical precision over object keys.
💻 100 Club locked in (100 pushups, situps, squats)
💧 2.0L hydration complete
⚡ All tests passed

Day 15/90 — Winter Arc ❄️
Woke up at 10:40 AM (target was 7:00 AM) and almost called it.
But a late start doesn't mean a failed day.
