Engineering meets

AI-Augmented Development

I integrate Claude Code and Cursor directly into my workflow as a force multiplier. I designed and built a custom agentic workflow system that automates ticket analysis, code exploration, PR creation, and retrospectives — actively used across my iOS projects.

📡

Streaming Expert

Specialized in live and on-demand video delivery. Currently working on a platform serving tens of millions of monthly users — owning player stability, auth flows, and engagement analytics.

🏗

Architecture-First

Clean Architecture, MVVM, modular design, and protocol-oriented Swift. I write code that teams can maintain, onboard into, and scale — not just code that ships once.

My process with
every client.

01

Discover

Deep dive into the codebase, tickets, and team context. I understand the problem fully before writing a single line.

02

Align

Sync with leads, stakeholders, and product to validate the approach, surface risks, and agree on priorities.

03

Plan

Break down the work into clear phases with effort mapping, edge cases identified, and execution sequence defined.

04

Build

Clean, test-driven implementation — AI-accelerated where it adds speed without sacrificing ownership or quality.

05

Review

Thorough code review, QA validation, cross-platform and design alignment before anything touches production.

06

Ship

CI/CD delivery, monitoring, and a retrospective to close the loop — so every cycle is better than the last.
