Software Engineering Manager II · Geo Engineering, Grab — leading Consumer Maps across three hubs.
Three years leading Grab's Consumer Maps engineering across three hubs — Singapore, Beijing, and Jakarta — spanning the SDKs behind the Grab app's home-screen map, wayfinding, and points-of-interest surfaces used by tens of millions of consumers every month. Engineering Owner for non-functional priorities across the Passenger, Driver, and Merchant apps, and technical gatekeeper for release stability across 20+ core SDKs. An AI-first builder-manager who has turned agentic tooling into a repeatable team practice, while personally shipping the org's hardest platform migrations and growing four direct reports into autonomous technical leads.
Five legs of a three-year build-out, from turning around a sinking platform to running crisis response for the whole Driver app.
Owns the Consumer Maps NFP roadmap — the Kotlin 2.1 / Android 36 migration, the Nav 2.0 / MapLibre rearchitecture, Garnet Taiwan localisation, and experimentation-infra cleanup — translating multi-quarter technical bets into shipped roadmap items.
Product surfaces under his scope reach massive consumer traffic: Trip Planner (1.97M MEU), Search & Discovery (10.43M monthly sessions), and cross-sell DineOut discovery (~6M weekly unique users).
Spotted that third-party map traffic could be converted into Grab bookings, and turned that insight into "Grab as a Navigation App" — now an estimated ~US$80K/week revenue line. Structured a DGNSS precise-positioning partnership spanning Qualcomm, OPPO, and SwiftNav — a hardware-to-software strategic bet, not just an internal roadmap line.
Manages 8 direct reports today, with a 9th offer already out — a team he's actively grown, not just inherited. Coached four leads — Parking, Trip Planner, ParaTransit, and Discovery — into autonomous "cyborg" owners of their own surfaces; their track record under his mentorship: 1 promotion, 2 TGW Awards, and 2 CEO Awards earned by the people he grew, plus a major contribution to a report's own G6 promotion.
Has handled the harder side of people leadership too: successfully managed 2 performance-improvement cases and coached two borderline performance ratings back to a positive trajectory. Hiring manager who stood up a new navigation team in Jakarta from zero — new hires ship production code within roughly 7 days, backed by onboarding guides he built.
Your leadership taught me more than just technical or execution skills — it shaped how I think about responsibility, clarity, and growth as an engineer. A mentee, on departure — Jan 2026
Turned around the Map Your City crowdsourcing platform as a first-time EM in Dec 2022, and built Grab's homegrown in-house navigation stack now powering the entire Driver app — both started as "sinking ships." Personally shipped the Kotlin 2.1 / K2 compiler and Android SDK 36 migration for kartapoi-sdk — KAPT→KSP, edge-to-edge UI across 22 screens, 5 SDK migrations, 1,385 unit tests green.
Sole architect of the Consumer Map Feature Flag Unification design, and led the 2.5-year, cross-platform KartaPOI Generic build spanning Android and iOS. Architectural gatekeeper for both release trains — blocks non-compliant MRs on sight ("this will lead to a crash in prod") and is the primary investigator for the highest-severity native crashes, including historic libgrabmap-gl.so memory-corruption bugs no one else had traced.
Partnered across 10+ tech families in the last three halves — Omni, Transport, Food, Local Life, FinID, Driver App, PAX Core, CX, DAX Core, Map Ops — as the go-to bridge for Navigation, Map Your City, and Consumer Maps. Drove MapMyDeals as a "One Grab" collaboration across Geo, Omni, and Food, then formalised it into a reusable multi-domain blueprint.
Bridges the Garnet Taiwan market-entry effort with localisation and content-ops teams across the Passenger, Driver, and Merchant apps, and is sought out by peer engineering managers and senior ICs for review of org-level priorities documents beyond his own team's scope.
Took command of the February 2026 Navigation Incident — coordinating engineering and QA reproduction, feature-flag rollback, and recovery across domains during a live crisis. Coordinated a separate CTO-1-level executive escalation and rollback approval during a severity-1 driver-app crash incident.
Runs structured "what went well / what could improve" incident retros, and has used them to fix real process gaps: criticality misclassification, delayed on-call escalation. Led the rotation of hardcoded API tokens across 5 SDKs after a security finding, and personally raised the fix for a DAX security vulnerability.
Eight numbers that trace the reach and depth of his ownership — from the surfaces millions open daily to the platform work no one sees.
Shaped initiatives reaching 10M+ monthly sessions by synthesising insight across Product, Data, and Design.
Ran 5+ major platform migrations in parallel in H1 2026 without breaking release stability.
Final go/no-go authority on PAX & DAX release trains; primary investigator for the highest-severity native crashes.
Brokered alignment across 10+ tech families in 3 halves — Omni, Transport, Food, FinID, Driver App.
Grew 4 reports into autonomous leads; managed 2 PIP cases and reversed 2 borderline performance ratings.
Built the Jakarta navigation team from zero; new hires ship production code within ~7 days.
92nd-percentile AI tool usage at Grab; authored Claude Skills now used org-wide for migrations.
Root-caused native memory-corruption crashes (libgrabmap-gl.so) that had gone untraced for years.
kartapoi-sdk, kampungmap-sdk, and dax-map-navigation across Android and iOS, plus review ownership on a native C++/JNI map-matching engine.
Direct exposure to the Kampung Go backend; drove migration of legacy feature flags onto the ConsumerMapExpVar experimentation system.
Reviews geosmartkit's computer-vision ID-verification models; owns the recommendation-driving Search & Discovery and Trip Planner surfaces.
Built and demoed an internal AI coding orchestrator to peer EMs; authored Claude Skills used org-wide; gave "Road to Super Engineering" on managers of AI agents.
Hands-on stack: Kotlin, Java, Jetpack Compose, SwiftUI, NDK/JNI, TensorFlow on-device, Room, RxJava, MVVM/VIPER, JUnit/Mockito, Cursor AI, Copilot, OpenAI — plus people management, sprint planning, and cross-team delivery.
Condensed from the April 2025 resume — earlier mobile leadership that led into Grab Consumer Maps.
Leading senior engineers on cross-platform SDKs spanning on-device ML, map matching, and Compose UI kits for a super app with 10M+ DAU. Driving AI-tool adoption for productivity and business impact. Earlier as Lead Software Engineer on GrabDriver Maps & Navigation: MVVM + RxJava migration, Kotlin conversion, localisation, and test coverage 70%→80% for an app with 10M+ downloads.
Re-architected into VIPER, owned release lifecycle and API contracts, redesigned search filters and homepage widgetization, shipped the Wizard loyalty feature, cut latency, and migrated the codebase to Kotlin for an app with 10M+ downloads.
Owned full development lifecycle across feed and story creation — OkHttp, ExoPlayer, custom gestures/animations, caching, and APK size/memory optimisation for 5M+ downloads.
Shipped Material Design apps with maps, GCM, Retrofit/Picasso, Facebook SDK, and AWS uploads — including Vyomo (salon aggregation, later Naturals@Home) and other on-demand products.
Senior Secondary, Hamdard Public School / Hamdard University — 86% (2010).
Muddassir is a cornerstone of GEO stability, engineering excellence, and the mobile ecosystem… one of the few EMs in Grab who work in more than one domain.
Allowed the Geo team to fulfill all commitments… one full week ahead of schedule.
Your leadership taught me more than just technical or execution skills — it shaped how I think about responsibility, clarity, and growth as an engineer.
