About Arun

One of the sharpest iOS minds
you haven't hired yet.

I'm Arun Nama — Senior iOS Engineer, AI Mobile Architect, and founder of a boutique engineering consultancy specialising in high-stakes mobile and AI product work. Over 12 years, I've architected flagship iOS apps across fintech, healthtech, and enterprise — products used daily by millions of people.

I work at the intersection of native iOS craftsmanship and applied AI. That means SwiftUI performance that rivals the best Apple apps, combined with on-device ML, RAG pipelines, and LLM integrations that actually ship and scale. I don't do demos; I deliver production systems.

Teams bring me in when they need an architect who can spot the flaw in a design review, mentor a mid-level team into senior engineers, and represent technical decisions in the boardroom — all in the same week.

What I Do

Elite engineering,
precisely applied.

I consult with startups and enterprises that need elite mobile and AI engineering — not agencies, not generalists. Specialists.

📱

iOS Architecture & Engineering

SwiftUI, UIKit, Combine, async/await — architecting iOS apps from the ground up or rescuing ones that ship slow, crash often, or scale poorly. App Store launches handled end-to-end.

🧠

AI Integration for Mobile

On-device inference with Core ML, Vision, and Natural Language. LLM-powered features via RAG, streaming APIs, and custom fine-tuned models — built for mobile constraints and user delight.

🏗️

Mobile Platform Architecture

Defining the technical foundation for multi-team iOS (and cross-platform React Native / Flutter) programmes. Module structure, CI/CD pipelines, and dependency strategies that scale to 50-engineer orgs.

☁️

Cloud & Backend for Mobile

FastAPI and Node.js backends optimised for mobile consumption. AWS, serverless functions, push infrastructure, and sync architectures that keep apps fast even on weak connections.

🔍

RAG & LLM Product Engineering

Production RAG pipelines with hybrid search, semantic re-ranking, and vector stores (Pinecone, Weaviate). Turning LLM prototypes into reliable, cost-efficient products at scale.

🎯

Tech Leadership & Advisory

Fractional CTO engagements, architecture reviews, and hands-on team mentoring. I work with engineering leaders who need a trusted technical partner — not a consultant who disappears after the deck.

Technical Skills

Selected Work

Production systems,
not toy demos.

A handful of engagements from the last three years. Most client work is under NDA — what's shown here is open or public.

Full-featured SwiftUI banking app — custom charts, biometric auth, real-time transaction sync via WebSockets, and WCAG AA accessibility. Shipped to 1.2M users with 4.8★ App Store rating and zero P1 crashes on launch.

Swift 5.9 SwiftUI Combine Core Data Biometrics

iOS app running a 3B-parameter quantised LLM entirely on-device via Core ML and the Neural Engine. Sub-200ms first-token latency on iPhone 15 Pro. Privacy-first — no data ever leaves the device. Featured by Apple.

Core ML Swift Neural Engine GGUF Metal

Enterprise RAG platform with hybrid BM25 + semantic search, cross-encoder re-ranking, and streaming. Ingests 2M+ documents with sub-300ms p95 latency. Also ships as a native iOS SDK for enterprise clients.

Experience

12 years.
Earned, not claimed.

A track record built across startups, scaleups, and enterprise programmes — always hands-on, always shipping.

2022 – Present

Nama Engineering

Founder & Principal iOS / AI Architect

  • Founded boutique iOS & AI engineering consultancy serving Series B–D startups and two Fortune 500 clients across fintech and healthtech.
  • Delivered LinguaAI, an on-device LLM iOS app running 3B-parameter models on the Neural Engine — featured by Apple on the App Store.
  • Architected IntelliQuery RAG platform serving 50k+ enterprise users at sub-300ms latency; built companion iOS SDK used by 12 enterprise clients.
  • Reduced client inference costs by 60% through quantisation, caching, and request batching — $800k annual saving at one client.

2018 – 2022

NovaMind Technologies

Principal iOS Engineer & Mobile Architect

  • Led iOS architecture for a flagship fintech app shipping to 1.2M users — introduced SwiftUI across the whole product 18 months before competitors.
  • Defined the mobile platform strategy for a 30-engineer iOS team: modular monorepo, feature flag system, and CI/CD pipeline on Bitrise.
  • Built Core ML inference pipeline for real-time transaction classification — 94% accuracy, runs entirely on-device.
  • Grew the iOS team from 4 to 14 engineers; 5 direct reports promoted to senior/staff level within two years.

2015 – 2018

Vertex Global Solutions

Senior iOS Engineer

  • Shipped 8 iOS apps across healthcare, retail, and B2B SaaS — three featured in the App Store Best New Apps section.
  • Designed offline-first sync architecture using CoreData + CloudKit for a healthcare app operating in low-connectivity environments.
  • Introduced accessibility-first development practices; apps passed WCAG 2.1 AA audit across the board.

2012 – 2015

DataStream Labs

iOS Developer

  • Early career building iOS apps during the Objective-C → Swift transition era — learned to write clean, maintainable code from first principles.
  • Owned the full lifecycle of a real-time data visualisation app: design, development, submission, and post-launch support.
What Clients Say

Results speak.
So do clients.

Arun is the kind of iOS engineer you read about but rarely hire. He walked into our codebase, diagnosed a performance problem in 48 hours that our team had chased for six months, fixed it, and then restructured the architecture so it couldn't happen again. He didn't just solve the problem — he made us better engineers.

Sarah Mitchell CTO, NovaMind Technologies

We brought Arun in to evaluate our AI integration strategy. Three months later we had a production RAG system serving our enterprise clients and an iOS SDK that our sales team uses as a differentiator in every deal. He's the rare engineer who can operate at system architecture level and then write the hardest pull requests himself.
