Mobile architecture
Design modular Flutter, Android, and iOS systems that can support multiple teams, release trains, and feature domains without turning the app into a single fragile codebase.
Mobile Solutions Architect
Ganesh Kanna Subramanian
I turn complex enterprise product needs into maintainable mobile platforms, governed delivery systems, and integration-ready architectures across FinTech, insurance, identity, and data-led programs.
Portfolio focus
Evidence of architecture, not just a list of technologies.
This portfolio is organized around the problems I solve: splitting large apps into governed modules, aligning APIs and mobile delivery, making releases predictable, and guiding teams through enterprise product complexity without losing engineering clarity.
Capability map
The capabilities I bring into a program.
Enterprise integration
Translate banking, insurance, identity, retail, CRM, and field-force requirements into secure API-led mobile and backend workflows.
Delivery governance
Set the working system around engineering: branching, code ownership, environments, build pipelines, release approvals, and defect triage.
Data and platform thinking
Bring data engineering and cloud architecture judgment into product decisions, especially for analytics, ETL, reporting, and platform-scale workflows.
Selected case studies
Enterprise products with real architecture pressure.
Aditya Birla Capital
ABCD Super App
FinTech, insurance, lending, investments, payments
Flutter, React, Spring Boot, MySQL
Challenge
A large financial super app needed multiple business lines to move in parallel while preserving app quality, release control, and platform consistency across Android and iOS.
Approach
- Structured a Flutter monorepo with 15+ feature packages and 10+ reusable internal SDK libraries.
- Defined governance for branching, CODEOWNERS, CI/CD, environments, release approvals, and quality gates.
- Aligned product, backend, QA, and mobile teams around integration contracts and delivery checkpoints.
Impact
- Reduced friction across feature teams by making ownership and package boundaries explicit.
- Improved release discipline across dev, SIT, UAT, CUG, and production environments.
- Created a maintainable foundation for finance modules with different compliance and business needs.
Confidential program
Functional ID Creation
Digital identity, government-scale workflow, smart driving license
MOSIP Framework
Challenge
A smart license identity program required secure registration, identity lifecycle thinking, performance-aware design, and clear mapping from regulation to implementable architecture.
Approach
- Mapped business, regulatory, and security expectations into platform architecture decisions.
- Used MOSIP concepts to shape identity creation, validation, issuance, and management workflows.
- Guided technical direction with attention to scalability, security, and operational handover.
Impact
- Established an implementation strategy for a high-trust identity platform.
- Created a delivery path that balanced compliance, usability, and system reliability.
- Helped stakeholders reason about identity workflows beyond screens and APIs.
ICAT / CCM
Enterprise Data Warehouse and ETL Orchestration
Insurance data, reporting, analytics, migration
PySpark, Databricks, Teradata, MS SQL
Challenge
Insurance customer data had to be consolidated into an enterprise warehouse with clean mapping, validation, and repeatable movement between Big Data and relational systems.
Approach
- Designed ETL flows for schema mapping, regex sanitization, incremental loading, and data-quality checks.
- Supported Big Data to RDBMS integration patterns for reporting and downstream analytics.
- Provided architecture validation during migration and stakeholder planning discussions.
Impact
- Improved reliability of data movement into reporting-ready structures.
- Made transformation rules more explicit and maintainable for long-running data operations.
- Connected engineering detail with business reporting needs.
EY / Tata AIA Life
Siddhi Super App
Insurance business operations, unified employee access
Flutter, Spring Boot
Challenge
Business users needed one coherent app experience across policy, customer, premium, commission, dashboard, lead, learning, and news workflows.
Approach
- Designed a multi-module app structure with unified access to core insurance workflows.
- Coordinated frontend, backend, and stakeholder expectations around a consistent user journey.
- Focused on interoperability and reduced repeated credential handling across business applications.
Impact
- Created a practical super-app model for internal insurance operations.
- Improved consistency across fragmented business workflows.
- Supported a delivery model that could evolve module by module.
Architecture proof
Patterns I repeatedly use to make complex systems workable.
Super-app module boundaries
- Shell app
- Feature packages
- Internal SDKs
- Release governance
Enterprise API integration
- Business workflow
- API contract
- Auth and validation
- Mobile UX
ETL operating model
- Source data
- Sanitize and map
- Incremental load
- Reporting layer
Delivery leadership
The seniority is in the operating system around the code.
- Architecture reviews and solution validation
- Client and stakeholder technical consulting
- Code review discipline and team mentoring
- Release planning across dev, SIT, UAT, CUG, and production
- Performance-focused debugging and issue triage
- Mobile, backend, QA, and product coordination
