Systems that ship,
and the decisions behind them.

Bank of Punjab needed real-time balance, withdrawal, transfer and alert notifications driven directly off core banking activity, with balance accuracy and core-system load as critical constraints.

Integrate the IRIS transaction switch with the SMS engine event-driven, not by polling. Map switch events to notification triggers with formatting, delivery and account routing as separate concerns.

Event-driven notifications avoided continuous database polling. Defensive handling of partial, reversed, and duplicate transactions reduced the risk of incorrect balance messages.

Multiple organizations needed end-to-end elections — onboarding, voter records, election setup, and reporting — with isolated tenant data on one platform.

.NET 6 on Clean Architecture with DDD: election rules modeled as first-class domain concepts, independent of delivery and storage. Tenant boundaries enforced at the domain layer, not the query layer.

Per-tenant customization without forking logic. New organization onboarding became configuration, not development. Domain tests run without infrastructure.

Three smart-city platforms needed RESTful backends with clear domain separation, high availability, and room to grow independently — under aggressive timelines.

Modular .NET Core services over a shared kernel: each platform owns its domain, shares cross-cutting infrastructure (auth, logging, data access) instead of duplicating it.

Shared authentication, logging, and data-access components reduced duplicated implementation while preserving clear domain boundaries between the platforms.

A grocery business in Cyprus needed a consumer app and CRM covering ordering, inventory, and payment processing, with failures represented clearly across the workflow.

TypeScript/React front end over a hardened payment integration: idempotent order creation, explicit failure states, and reconciliation built in from day one rather than bolted on.

Idempotent order creation, explicit failure states, and reconciliation made payment handling easier to operate and troubleshoot without duplicating orders.

A terminal coding agent must read source, edit files and run shell commands. Executing those server-side means every user's proprietary code and shell access transit a third party — disqualifying for most teams. And a "plan mode" enforced by prompt instructions is a suggestion, not a safety property.

The server defines schema-only tool contracts and holds no implementations; the CLI executes them locally, sandboxed to the project root, and auto-continues the agent loop. Plan and Build modes swap the model's exposed toolset between read-only and full write/shell — enforced at the contract layer, not the prompt.

Source and shell access never leave the machine. The model cannot edit in Plan mode because no write tool exists to call. Token-metered billing rides on idempotent usage events with balance-gating before the model call.
