Avismara Hugoppalu

Senior iOS Engineer · Toptal Top 3%

Senior iOS engineer with thirteen years shipping end-to-end mobile products — iOS primary, Android secondary — across startups, unicorns, and Fortune 500 clients. A hands-on architect who ships fast without trading away scalability: modular SDKs, server-driven UI, cross-platform Rust cores, device attestation, performance forensics, and modern Swift (Combine, structured concurrency). Known for a designer’s eye — pixel-perfect, considered interfaces. Lately pointing that same curiosity at AI engineering — building agent infrastructure, retrieval, and evaluation in the open. Guest lecturer in Algorithms & Data Structures and Object-Oriented Design.

Selected Highlights & Impact

Building with AI — Independent & Open Source

AksharaMCP · RAG · Eval

A zero-UI conversational agent for Indian schools — a scoped LLM agent answering parents over WhatsApp from the school’s own data, with access control enforced at the tool boundary and a ≥95% grounding bar.

AgentKitOpen Source · Swift 6.2

A Swift-native agent orchestration SDK: a @SessionSchema macro, SimulatedSession for deterministic testing, and a transcript-first architecture. My bridge from apps to agents, in code.

Socratic tutorEval-gated CI

~600 lines of dependency-free Python that teach me how language models work and grade me adversarially: an append-only evidence log, mastery derived from that log (un-gameable), and an eval-gated build track ending in a deployed service.

Professional Experience

Toptal — Senior iOS Developer (Top 3%) · Remote
Aug 2021 — Present
High-impact iOS for clients from influencers to Fortune 500s, often in ambiguous contexts needing rapid diagnosis, architectural clarity, and safe, fast delivery. Selected engagements:
  • AI Music Generation App (under NDA) — Sole iOS engineer on the first SwiftUI version, shipped 0→1 to the App Store (4.8★, 7.9k reviews). Owned core architecture, CI/CD, and dev guidelines; helped interview and stand up the in-house iOS team.
  • Scrybe — Music Streaming App — Sole iOS engineer on a full revamp: modern visual language and a multi-tier StoreKit subscription model (song/album/artist) with robust entitlement handling; GitHub Actions CI/CD.
  • ASAPP (New York) — SDK engineer on a high-scale chat platform (10M+ req/mo); co-architected backend-driven UI on a shared Rust core (UniFFI → Swift + Kotlin) — enterprise flows ship server-side, no app release, frozen SDK versions degrade safely; owned Rust symbolication in the iOS crash pipeline; refined CircleCI pipelines.
  • Private Social App (London) — chat and feed modules with offline-first capabilities.
campus.build — Founder & Tech Head · Bangalore
Oct 2019 — Dec 2020
  • Built presence across 12+ engineering colleges and a 6,000+ student community.
  • Owned UI/UX in Sketch; led Node.js backend and admin tooling.
Infrrd Technologies — Mobile Lead · Bangalore
Jan 2017 — Oct 2019
  • Led a 12-member iOS + Android team across SDK and app work.
  • Shipped bill-capture and ID-document SDKs (OpenCV — edge/perspective correction, glare & blur detection, OCR extraction with real-time guidance).
  • Standardized architecture and CI/CD; tripled billable capacity via a graduate training pipeline.
galleri5 — iOS Developer
2016 — 17
  • Sole iOS engineer inception→launch; led UI/UX. Scaled to 15,000+ users/month, 4,000+ images/month.
Rare Mile — Mobile Developer
2014 — 16
  • Child-location tracking app (GPS, geofencing, background updates) and a mobile payments/wallet app (QR payments, secure transactions).
