01 About

Senior engineer. Ships ideas, not slides.

I design, architect, and build software — currently leading the Core Payments team for the Titan platform. But payments is one chapter, not the whole book.

Twelve years of .NET and Azure across payment orchestration, telecom e-commerce and warehouse management (Shields Marketplace, used by global tech giants), and enterprise internal portals — plus four promotions in seven years at Think Digitally, up to Head of Cloud & Platform Services.

AI-augmented engineering is leverage, not replacement: Claude, Copilot, Cursor, and MCP compress the idea-to-production loop. Senior judgement still owns design and the final review.

06 Case studies

Stories from the engine room.

Context

Small and mid-size livestock farms have no purpose-built software for herd records, expense tracking, and investor reporting — generic tools don’t fit the domain, and the original single-tenant app (FarmHub) needed a real multi-tenant rearchitecture to scale beyond one farm.

Decision

Shared-database multi-tenancy with PostgreSQL Row-Level Security as a defense-in-depth backstop over existing app-level farm_id filters — production runs as a least-privilege, non-superuser Postgres role so RLS is actually enforced, not just declared. Global account identity with a tenant-picker for multi-farm users, per-farm branding, platform-admin tooling, GDPR export/erasure, Google/Microsoft SSO, and a Recharts analytics dashboard.

Outcome

Multi-tenant rearchitecture shipped to main — RLS-enforced tenant isolation live in production, SSO, per-farm currency, a redesigned dashboard, and a companion marketing site. Renamed to e-Maveshi and its own domain acquired as the product moved toward public launch.

What people say.

I had the pleasure of working alongside Saad at Think Digitally, where his exceptional skills as Head of Development were consistently on display. Saad's technical expertise in .NET development is truly outstanding. He possesses a deep understanding of the framework and stays current with the latest advancements in the field. What sets Saad apart, however, is his remarkable ability to tackle complex problems and analyse difficult situations.

Got an idea?
Let’s ship it.

I take on a small number of consulting and advisory engagements alongside my main role — payments, cloud architecture, DevOps delivery, or AI-augmented engineering practice. LinkedIn is the fastest path.
