Explore his focus and product architecture. https://savisaluwadana.github.io/engineering/Architecture reference2026-11-12T00:00:00ZExplore Savi Saluwadana’s product architecture: Go APIs, MCP access boundaries, local-first HR workflows, tenancy and transactional operations, with project references. https://savisaluwadana.github.io/engineering/agentic-systems/Agentic systems architecture2026-11-12T00:00:00ZExplore Savi Saluwadana’s agentic systems work through rental operations, evidence-led research and developer workflows: MCP, API permissions, state and human review. https://savisaluwadana.github.io/open-source/Public source and open-source interests2026-11-12T00:00:00ZExplore Savi Saluwadana’s public engineering repositories, architecture references and open-source development interests in Go, cloud-native software and agent tools. https://savisaluwadana.github.io/products/avara/Avara Real Estate2026-11-12T00:00:00ZProperty discovery, transactions and host operations in Sri Lanka. This diagram summarizes the repository’s property, booking and payment boundaries. PayHere and S3 require deployment-specific configuration. https://savisaluwadana.github.io/products/blu/Blu.lk2026-10-04T00:00:00ZHome-service discovery, booking and fulfillment in Sri Lanka. This diagram covers the core service platform. Payment-provider availability depends on integration configuration; no specific online payment launch is claimed here. https://savisaluwadana.github.io/products/freshpick/FreshPick / FreshOnTime2026-11-12T00:00:00ZFood commerce, producer onboarding and scheduled recurring deliveries in Colombo. Customer checkout and subscription baskets currently use cash on delivery. Automatic recurring card charging is not implemented. Subscription baskets and recurring grocery orders are distinct workflows. https://savisaluwadana.github.io/products/timelyhelp/TimelyHelp.lk2026-10-04T00:00:00ZProduct and frontend work for practitioner discovery and consultation journeys. Savi’s portfolio contribution is product and frontend work. This page summarizes that frontend boundary and does not claim ownership of the full clinical backend. https://savisaluwadana.github.io/products/devrelos/DevRelOS2026-10-04T00:00:00ZA self-hosted beta for discovery, engagement and outcome measurement. This project is a self-hosted beta. External providers require credentials and policy configuration; consequential outreach follows approval workflows. https://savisaluwadana.github.io/products/property-os/Property Management OS2026-11-12T00:00:00ZMulti-tenant rental operations and controlled agent-assisted work. MCP calls the same authenticated HTTP API as other clients and has no direct database connection. Advanced financial writes and other domains remain subject to the project’s implemented tool scope. https://savisaluwadana.github.io/products/rapidreach/RapidReach2026-11-12T00:00:00ZDeveloper publishing and tool discovery with a small CMS. RapidReach uses one Next.js application with MongoDB and Blob storage; there is no separate backend service. Publishing and media require a configured deployment. https://savisaluwadana.github.io/products/advance-hris/Advance HRIS2026-11-12T00:00:00ZHybrid web and local-first desktop HR operations. Local-first refers to the desktop console. The cloud database remains authoritative. Payroll-ready attendance boundaries do not mean a complete payroll-processing product is included. https://savisaluwadana.github.io/products/nexus-pos/NexusPOS2026-10-04T00:00:00ZCheckout and store operations with an optional Electron desktop shell. Electron is an optional desktop shell. The portfolio does not claim a complete offline checkout engine or a tenant-isolated hosted retail service. https://savisaluwadana.github.io/products/academix/Academix2026-11-12T00:00:00ZStudent, academic and fee operations in a role-aware workspace. The account and plan surfaces support a SaaS direction. Automated billing and broader tenant-isolation work should be checked against the current project roadmap rather than assumed complete. https://savisaluwadana.github.io/products/acme-accounting/Acme Accounting2026-10-04T00:00:00ZSingle-company financial operations backed by a double-entry ledger. The current application is designed for one company and one administrator identity per database. It is not a tenant-isolated accounting SaaS backend. https://savisaluwadana.github.io/products/eventos/EventOS2026-10-04T00:00:00ZQuick provider matching and full event procurement. Payments are submitted and reconciled manually in the current MVP. This is a Next.js and PostgreSQL application; a Supabase service is not required for the documented runtime. https://savisaluwadana.github.io/products/restaurantos/Plate Restaurant OS2026-10-04T00:00:00ZRestaurant point of sale and coordinated order operations. The product is under development. POS, kitchen and online ordering share a Next.js application and MongoDB data layer; external integrations require deployment-specific configuration. https://savisaluwadana.github.io/products/pain-intelligence/Pain Intelligence Lab2026-11-12T00:00:00ZLocal research software for exploring repeated needs and evidence-backed project ideas. The repository currently describes an early community alpha for local use. The web app and desktop app have different capabilities; source content retains third-party data-use restrictions. https://savisaluwadana.github.io/products/ad-performance-agent/Ad Performance Analysis Agent2026-10-04T00:00:00ZAn advertising analytics and reporting prototype. Google Ads and Supermetrics connection endpoints are currently mocks. Scheduled demonstration runs use generated sample CSVs and in-memory configuration, rather than a durable live account-ingestion pipeline. https://savisaluwadana.github.io/products/medicare/MediCare2026-10-04T00:00:00ZPatient administration, appointments, clinical records and billing. The main clinic API and embeddable scheduling API use separate service boundaries. Server-enforced roles separate clinical, billing and administrative access. https://savisaluwadana.github.io/insights/Engineering insights2026-11-12T00:00:00ZTechnical notes on software architecture, Go, PostgreSQL, platform engineering, MCP and durable agentic systems. https://savisaluwadana.github.io/insights/mcp-permission-boundaries/MCP Permission Boundaries2026-11-12T00:00:00ZKeep agent tools behind the authenticated application API and retain authorization in domain services. https://savisaluwadana.github.io/insights/durable-agentic-workflows/Durable Agentic Workflows2026-11-12T00:00:00ZPersist workflow state, design safe retries and model human approval explicitly. https://savisaluwadana.github.io/insights/go-modular-monolith-saas/Go Modular Monolith for SaaS2026-11-12T00:00:00ZUse explicit domain boundaries before introducing distributed-service complexity. https://savisaluwadana.github.io/insights/platform-engineering-paved-road/Platform Engineering Paved Roads2026-11-12T00:00:00ZStandardize delivery while keeping state, observability, ownership and escape hatches visible. https://savisaluwadana.github.io/insights/postgres-multitenancy-boundaries/PostgreSQL Multi-Tenancy Boundaries2026-11-12T00:00:00ZResolve tenant context before data access and treat database isolation as defense in depth.
