iOS + Flutter developer

Jaseel O.P

I build reliable mobile apps for healthcare, logistics, travel, education, and service teams.

iOS developer with 7 years of Swift, Objective-C, UIKit, SwiftUI, and hands-on Flutter experience. I like mobile products that feel stable in the messy parts: booking flows, maps, payments, reports, audio, subscriptions, and release cycles.

Remote collaboration with product teams

My strongest work is turning operational workflows into mobile apps people can actually depend on: clear interfaces, predictable state, careful API integration, and calm shipping habits.

Selected work

Compact stories from shipped mobile products.

Each project is framed around what the app needed to make easier, not just the frameworks used to build it.

Invigorix

Official Invigorix positioning: healthcare delivery improved through technology, digital platforms, patient engagement, and operational tools.

Official platform context

A healthcare technology platform spanning virtual care, patient experience, feedback, reputation, marketing, and operational visibility.

The official site describes Invigorix as a platform that combines technology, marketing, and healthcare-domain understanding to raise healthcare delivery standards and support personalized patient care. In the portfolio, this better explains why the mobile work mattered: the app was part of a broader hospital operating system, not just a standalone booking screen.

Invigorix highlights

Platform Scope

Invigorix supports digital healthcare journeys with patient access, teleconsultation, records, billing, and engagement-focused mobile workflows.

Hospital Impact

The platform context highlights practical hospital outcomes, including stronger teleconsultation support and smoother patient-service visibility.

My Contribution

Built patient-facing iOS flows for appointments, reports, bill payments, and service interactions with maintainable Swift + MVVM architecture.

Hospital proof

The official site’s updates mention Zulekha Hospital upgrading the Invigorix application for improved teleconsultation and LifeLine Hospital joining hands with Invigorix.

My mobile contribution

Built patient-facing iOS flows around appointment booking, lab report access, bill payments, and hospital service interactions, keeping the app structure maintainable with Swift and MVVM.

Restronet

Restaurant apps for Paragon Group, HiLITE, and Salkara with ordering, rewards, payments, and maps.

Problem

Restaurant customers and teams needed smoother ordering, tracking, and loyalty experiences.

Result

Delivered for multiple restaurant brands and operational use cases.

Heart Rate Monitor

Heart Rate Monitor・Pulse Rate (iPhone) focused on quick camera-based pulse checks, daily tracking, and a cleaner health-status view for users who want routine monitoring without extra hardware.

Problem

Users needed a fast and understandable pulse workflow with useful history, reminders, and dashboard visibility, while the app also needed stable performance and sustainable monetization.

Result

The App Store listing highlights camera-based pulse measurement, Apple Health saving, reminders, and dashboard history; this project covered implementation, iteration, and release updates for that end-to-end mobile experience.

Sunday App

Sunday (Sunrise Sunset Times / Sun Tracker) iOS work focused on location-based daylight planning with SwiftUI, combining visual solar-path context with practical daily timing data.

Problem

Users needed reliable sun-position and light-window guidance for planning shoots, outdoor activities, and location decisions, presented in a fast, easy-to-read iOS interface.

Result

Public app positioning highlights sunrise/sunset times, solar path prediction, and use cases like photography and outdoor planning; my contribution focused on the iOS SwiftUI implementation of those core product experiences.

BookMyPlay

BookMyPlay is a football and futsal booking platform focused on fast slot selection, nearby events discovery, and team coordination from mobile.

Problem

Players and organizers needed a faster way to find available grounds, reserve time slots, discover nearby events, and coordinate teams without fragmented chat-first workflows.

Result

The official BookMyPlay platform highlights field booking, nearby football events, team organization, match challenges, and flexible booking times; this portfolio entry reflects implementation work mapped to those user journeys.

iOSSwiftUIScheduling UXLocation-aware discovery

Rental booking apps visual covering flights, hotels, and car rentals

Rental Apps

Travel and rental-focused mobile app suite covering flights, hotels, and car-related booking flows under Lascade Kochi delivery context.

Problem

The product required reliable, high-traffic booking experiences across multiple verticals with complex API coordination, while preserving speed and clarity in user-facing journeys.

Result

Portfolio contribution focused on iOS UI implementation and long-term code maintenance for multi-vertical booking experiences including flights, hotels, and rentals.

Logistics management visual for shipping and transportation

eCabship & Forte Rapida

Logistics management mobile apps for shipment workflows, tracking visibility, and operational updates.

These apps were production logistics solutions and are now removed from the App Store; portfolio details are intentionally brief and focused on contribution scope.

Signpost Installer

Installer and field-operations app flow for logistics-style task execution, status updates, and day-to-day dispatch visibility.

The Android listing publicly represents the same product domain; this portfolio item reflects my contribution on the iOS Swift/UIKit implementation.

BuyBux

BuyBux is a voucher and coupon e-commerce platform built as dual Flutter apps: one for customers discovering and purchasing offers, and one for merchants managing listings, campaign visibility, and redemption-related workflows.

Problem

The platform needed to serve two different user groups with connected but distinct journeys: customer-side browsing and checkout, and merchant-side offer operations, inventory logic, and lifecycle updates.

Status

This project is currently not published on the App Store; portfolio details are based on implementation scope and delivery responsibilities across both app sides.

RentZone

A property finder app built for KomdeTech, designed to help users discover listings, review property details, and complete booking-related actions smoothly.

This app was delivered for production and later discontinued; portfolio details are intentionally concise and focused on implementation scope.
