About

I am a senior engineer who owns the product end-to-end: iOS, Android, web, and the APIs behind them. Most recently I spent 5 years at Grab, Southeast Asia’s super app, across Consumer, Driver, and Merchant. I work AI-first — vibe-coding first drafts in Cursor, then applying architecture, tests, and release discipline so the output is hire-me-tomorrow, not demo-ware. 15+ years, 50+ production apps across Grab, OYO, Kohl’s, and my own App Store account (24 personal apps, 3,700+ ratings).

How I ship in 2026

Companies want people who move fast with AI without lowering the quality bar. That is the job I already do.

Vibe-code, then verify

Cursor, agents, and tight loops for first drafts. I still own architecture, reviews, tests, and the release.

  • AI for speed, humans for judgment
  • No unreviewed agent output in prod
  • Specs, diffs, and measurable done

One owner, four surfaces

iOS, Android, web, and backend in the same head. Fewer handoffs, faster 0→1 and 1→n.

  • Swift / SwiftUI and Kotlin / Compose
  • Web clients and REST / service APIs
  • Product, design, and release in one thread

Quality teams can hire for

Crash-free sessions, coverage, CI/CD, and ratings — the metrics staffing teams actually ask about.

  • OYO: 3.7 → 4.7, coverage 4% → 32%
  • >99.97% crash-free at scale
  • Fastlane, Xcode Cloud, GitHub Actions

How I can help a team

Staffing for a mobile/full-stack IC, a 0–1 product, or an AI-accelerated delivery push. Architecture first, then speed.

Architecture Audit

Module boundaries, dependency flow, testing seams across iOS, Android, and backend. RIB • MVVM • MVI • VIPER • Clean.

  • Dependency review and refactor plan
  • Testability & seams assessment
  • Roadmap with milestones

AI-accelerated delivery

Stand up Cursor/agent workflows so the team ships faster without turning the repo into slop.

  • Repo rules, review gates, eval loops
  • Playbooks for vibe-coding in a team
  • Before/after cycle-time

CI/CD & Release Ops

Fastlane • Xcode Cloud • GitHub Actions. Reproducible builds, automated checks, safe releases.

  • Pipeline design & setup
  • Testing gates & quality bars
  • Release cadence & playbooks

Recommendations

What managers and reports say about working with me

“Alok and I worked together at Orahi. He is one of the most sincere and dedicated person, I ever worked with. He has eye for details in user experience and optimised iOS programming as skillset. I wish him all the very best for his future endeavors.”
Arun Bhati Founder & CEO at Orahi, Consat Orahi & 1 Million Founders Managed Alok directly · July 2021
“I have worked with Alok in OYO in the same team. I was a fresher there and being mentored by him was something I feel the best thing happened to me in initial phase of my career. His perfect learning roadmaps, assignments helped me to learn Swift quickly. His code reviews helped me to improve as a developer every day. He is highly experienced and down to earth. I could approach him for every small or big problem, the knowledge gap never came in between also he used to own team's problems that's the best thing about his personality. He is a very good mentor, a perfect team leader and the nicest of human being to work with.”
Sama Parveen SDE II @Disney+ Hotstar | MNNIT Allahabad Reported directly to Alok · March 2021
“I worked with Alok on an iOS project as his client. I had long technical discussions with him on the product and he showed excellent technical knowledge of iOS, mobile technologies and software engineering. Alok always exceeded my expectations regarding understanding the requirements and delivering high quality work on time. I highly recommend Alok and would love the opportunity to work with him again.”

Hiring for a senior IC who can own mobile, web, and backend — and actually use AI in the loop? I reply faster than an agent finishes a refactor.
