Enterprise Software Consultant
Enterprise Software Consulting · Modernization · Integration
I help businesses modernize legacy applications, connect SaaS and internal systems, build custom enterprise software, improve eCommerce and operational workflows, and turn complex technical processes into reliable production platforms.
What I help with
The emphasis is not on selling isolated technologies. Each engagement starts with the business problem, the existing systems and the operational constraints, then applies the right combination of architecture, modernization, integration, data and hands-on engineering.
Design, modernize and extend business-critical enterprise applications used by customer service, operations, inventory, procurement, finance and management teams.
CSR systems · workflow applications · approvals · returns · order operations · inventory tools · internal dashboards · audit trails
Modernize legacy applications and platforms without losing the business rules, data, SEO value or operational knowledge that made the existing system valuable.
Classic ASP / ASP.NET modernization · SQL Server systems · phased replacement · Shopify migration · data migration · cutover planning · post-launch validation
Integrate APIs, SaaS platforms, CRM systems and internal applications so information moves through the business as one reliable workflow instead of living in disconnected tools.
REST / GraphQL APIs · SDKs · WebSockets · scheduled services · platform authentication · event-driven workflows · CRM synchronization · operational integration
Support Shopify and broader eCommerce systems across migration, multi-store operations, orders, returns, payments, inventory, shipping and the internal applications behind the storefront.
Shopify · custom commerce workflows · multi-store integration · order sync · returns · product/catalog migration · SEO-sensitive migration · marketplace and fulfillment integration
Turn operational SQL and application data into trusted models, analytics and decision support for executives and teams who need to understand what is happening, why it is happening and where attention is required.
SQL Server · data modeling · ETL · Power BI · KPI design · operational analytics · business-rule interpretation · executive reporting · performance analysis
Build and secure payment workflows while treating gateway configuration, infrastructure, privileged access, fraud controls and compliance as part of the same production system.
Braintree · CyberSource · payment APIs / SDKs · C# backend payments · refunds · SSL · server hardening · PCI DSS · SAQ D · ASV remediation · fraud controls
Design software that connects physical operations with reliable system state—from barcode reconciliation and warehouse routing to carrier-aware shipment tracking and customer communication.
barcode systems · SKU resolution · warehouse reconciliation · box-level inventory · disposition workflows · shipment tracking · carrier-aware routing · tracking timelines · customer shipment communication
Cross-cutting capability
Across these projects I work at the boundary between business operations and technical architecture: deciding what should be reused, what should be replaced, where integrations belong, how data should flow, and how the final system should behave in production.
Map the real workflow, users, dependencies and business rules before changing the technology.
Separate responsibilities across application, database, integration, external platforms and infrastructure.
Use APIs, services, event-driven flows, scheduled processing or external handoffs according to the problem—not fashion.
Deployment, migration, security, validation, troubleshooting and operational continuity are part of the engineering work.
How I can engage
Review an existing application, database, workflow or integration and identify the practical path forward before a major investment.
Useful for: modernization decisions · performance issues · integration planning · architecture riskTranslate business requirements into application boundaries, data flows, integrations, security considerations and a realistic delivery plan.
Useful for: new internal systems · procurement workflows · platform integrations · replatformingDesign and implement the solution across frontend, backend, database, APIs and production integration where the project requires it.
Useful for: enterprise applications · workflow automation · commerce systems · operational integrationsImprove or replace parts of a long-running system while preserving critical business continuity, data and operational knowledge.
Useful for: Classic ASP / ASP.NET estates · SQL Server platforms · legacy commerce · staged migrationsA good fit
Existing software works, but parts of it need to be modernized without disrupting operations.
Several systems need to exchange data reliably and the workflow matters more than the API itself.
Operational users need a better application around processes that currently require manual searching or disconnected tools.
Commerce, payments, inventory, shipping or customer-service workflows have grown beyond what the current system handles cleanly.
Management has plenty of data but needs clearer operational insight and decision support.
Leadership & collaboration
“Beyond his technical acumen, what truly makes Hasham exceptional is his leadership and emotional intelligence. He understands not just the work but the people behind it, fostering collaboration and bringing out the best in his team. His ability to empathize with both colleagues and clients allows him to create solutions that are both effective and meaningful.”
Start with the problem
Start with the business problem. I can help determine whether the right answer is systems integration, legacy modernization, a custom application, better data visibility—or a combination of them.
