Mobile products · Realtime systems · Applied AI

Mobile products, realtime systems and applied AI, built end to end.

I design and build cross platform applications the whole way through: interface, application logic, backend services, data, realtime communication and the intelligent features in between.

  • FEATURED BUILDS FROM MANY SHIPPED PROJECTS
  • BSC COMPUTER SCIENCE (HONS) · SOFTWARE ENGINEERING & AI, IIUM
  • JIIICAS 2024 GOLD AWARD
  • PUBLISHED COMPUTER VISION RESEARCH

01 · DETECT APPLIED AI RESEARCH BUILD

DentXpert

A dental care companion that checks photos of your teeth for signs of caries using YOLOv8, then helps you learn prevention and find real care.

  • YOLOv8 detection in three tiers
  • Guided five angle photo capture
  • Prevention library built in
  • Clinic and dentist directory
  • Firebase accounts and content

This is where my applied AI habits started: give people clear model choices, guide their input, and frame results as a check to act on, never a diagnosis.

Model selection screen listing YOLOv8 Model 1 lite, Model 2 pro and Model 3 ultra, with a request for at least five photos from five angles.
DentXpert home screen greeting the user with two actions, check for dental caries and search for a dentist or clinic.

  • Leaderboards & friends
  • Progression economy
  • Theme shop

03 · OPERATE ENTERPRISE OPERATIONS · CONFIDENTIAL WORK PROJECT

AIMARA

A secure mobile operations environment for realtime communication, cases, calls, records and AI assisted messaging.

  • Realtime chat
  • Channel governance
  • Agora calls
  • AI Safe Mode
  • Device level security

Relevant for operational apps, secure messaging, realtime dashboards, AI assistance and complex admin workflows.

Read the case study →
A privacy tier chat where members appear as stable anonymised handles, with archive and reactivation system notices inline.
Operations dashboard with an Upcoming section and an Overdue list of calls and tasks tied to channels and assignees.

04 · COOK CONSUMER UTILITY · LOCAL FIRST

Grocs

A private kitchen companion that turns scattered recipes into meals users can cook with what they already have.

  • Local first, no account
  • 5-source recipe capture
  • On device OCR
  • FTS5 search · 168k index
  • Pantry aware matching

Relevant for local first products, content extraction, on device AI, SQLite search and privacy conscious architecture.

Read the case study →
Recipes tab showing 0 saved and 2,500 in the index, with search and status filters, plus index records from named sources.
Add screen with five capture routes: from a link, paste text, screenshot or photo, saved video, write it myself.

How I work

From constraint to handover

  1. 01

    Understand the product and constraints

    What the product must do, for whom, under which privacy, platform and budget realities, written down before anything is designed.

  2. 02

    Design the experience and the system

    Screens and state machines together. An interface that ignores its data model is a mockup, not a design.

  3. 03

    Build in testable increments

    Vertical slices that run end to end early, with the risky parts, realtime, native modules, AI, pulled forward, not saved for last.

  4. 04

    Validate across devices and edge cases

    Offline, mid action kills, hostile inputs, small screens, reduced motion. The edge cases are where products earn trust.

  5. 05

    Prepare for deployment and handover

    Store policy pages, environment configuration, documentation and a codebase the next person can actually pick up.

Experience & recognition

The path so far

  1. EDUCATION

    BSc Computer Science (Honours), IIUM

  2. WORK

    Devco, internship, then continued part time (ongoing)

    Hands on product engineering on a confidential enterprise platform: realtime systems, mobile security and AI assisted features (see the AIMARA case study). The part time engagement continues after graduation.

  3. 2024 · AWARD

    JIIICaS Gold Award, DentXpert

    Gold Award at JIIICaS 2024 for DentXpert, a YOLOv8 based dental caries detection system built as a final year project.

  4. RESEARCH

    Published computer vision research

  5. WORK

    Independent mobile and web development (ongoing)

    A steady run of client and personal projects since graduation: many mobile apps and web builds shipped end to end, alongside the continuing part time work at Devco.

Portrait of Salim Sadman

About

I'm a software & app developer from the International Islamic University Malaysia's Software Engineering & AI track. I like whole products more than isolated screens: the same hands that shape an interface should understand the state machine, the database and the failure modes behind it. The projects featured here are that belief shipped four different ways, and they sit on top of many more client and personal builds, mobile apps and web work alike, delivered since graduation alongside continued part time engineering at Devco.

Have a mobile product, realtime platform or AI feature to build?

I take on cross platform builds end to end, from first screen to backend, data and the intelligent parts.
