## Problem

Zenzop ek on-demand delivery app hai: khana, grocery, dawaiyan, aur rozmarra ki
zarooratein aapke darwaze tak. Delivery do cheezon par tikti ya girti hai jinhe
customer seedhe feel karta hai: kya mujhe pata hai mera order kahan hai, aur kya
ETA honest hai. Mera kaam tha wo apps banana jo dono ko sambhalein, zero se, iOS
aur Android ke liye.

## Decisions

**Do apps, ek kaam.** Maine dono taraf poori tarah React Native mein banaye: Shop
app jisse customer order karta hai, aur Rider app jise delivery partner chalata
hai. Har ek iOS aur Android par ship hua, taaki ek chhoti team charon surfaces par
ek saath move kar sake. Google Maps real-time geolocation aur route optimization
sambhalta hai, wahi reedh jo dono apps share karte hain.

**Live tracking jo locked phone mein bhi chale.** Rider ka phone poori trip jeb
mein rehta hai. Maine background live tracking banayi taaki rider ki position tab
bhi flow karti rahe jab app foreground mein na ho, aur iOS par main Swift ke saath
native gaya taaki Live Activities chala sakoon: order status aur rider progress
Dynamic Island aur lock screen par, taaki customer bina kuch khole dekh sake ki
uska khana kahan hai. Ek app jise log check karte hain aur ek app jis par log
bharosa karte hain, in dono ke beech yahi farq hai.

**Ek ETA engine, ETA andaaza nahi.** Delivery ETA ek waada hai. Maine ek engine
banaya jo ise distance matrices, live traffic, rider ki live position, aur route
ke historical averages se calculate karta hai, na ki ek seedhi-line ke andaaze se.
Isne ETA ki accuracy 28% badhayi, wo number jo customer har ek order par feel
karta hai.

**Load mein tez, fix mein tez.** Maine apps ko 30% tez load times ke liye refactor
kiya aur CodePush joda, taaki over-the-air updates poore store release ke bina
seedhe users tak pahunchein. Fixes aur tweaks usi din aate hain, agle review cycle
mein nahi.

**Docs taaki API bottleneck na bane.** Maine comprehensive Swagger API
documentation likhi taaki client aur backend teams tribal knowledge ke bajaye ek
single source of truth ke aadhaar par build, test, aur integrate kar sakein.

## Outcome

{/* TODO(saif): metrics slot, installs / on-time delivery rate / order volume.
    Qualitative until real numbers land. */}

Dono apps iOS aur Android par ship hue: ek customer app aur ek rider app zero se
bane, live tracking ke saath jo jeb mein bhi tikti hai, Dynamic Island par iOS Live
Activities, aur ek ETA engine jo baseline se 28% zyada accurate hai. Last mile
delivery ka wo hissa hai jise customer asal mein experience karta hai, aur ye apps
isi ko sambhala hua feel karane ke liye bane the.
