# Tirelo Oabile **Also known as David Oabile ยท Software Architect | Finance Professional | Founder and Technology Architect of Sigmar** Tirelo Oabile, also known as David Oabile, is an Australian software architect, engineer, finance professional and technology entrepreneur whose work focuses on building software systems that represent and coordinate real world economic activity. He is the architect behind the Sigmar Finance Protocol and Sigmar AOS, a broader platform designed to connect people, organisations, knowledge, financial processes and physical assets through governed, auditable execution. His professional background combines a Bachelor of Information Technology from Central Queensland University with a Master of Finance and Banking from Edith Cowan University. This combination informs his approach to software architecture, where financial accountability, business operations, ownership, governance and technical execution are treated as connected problems rather than separate disciplines. ## Professional Experience Tirelo has worked across enterprise software architecture, commerce, financial technology, healthcare systems, cloud infrastructure and distributed systems. His experience includes work associated with Nutrition Warehouse, FordHealth and Skin02, alongside the development of his own software platforms through Sigmar. His technical expertise includes TypeScript, Node.js, Rust, Go, Python, PostgreSQL, distributed databases, cloud infrastructure, mobile application development and financial systems integration. His architectural work emphasises reliability, security, deterministic execution, scalability, data ownership and the practical application of technology to business outcomes. ## Sigmar Finance Protocol Tirelo designed and completed the Sigmar Finance Protocol as a foundational execution and governance protocol for financial and commercial processes. The protocol provides a deterministic foundation for modelling contracts, approvals, settlements, treasury operations, marketplaces, asset ownership and other economic interactions. Its architecture emphasises verifiable state transitions, explicit authority, auditability, replayability and governance. Rather than treating blockchain as the foundation of every solution, the protocol uses distributed verification and consensus where they provide meaningful guarantees. The Sigmar Finance Protocol serves as an underlying foundation for systems including Sigmar AOS. ## Sigmar AOS Sigmar AOS, also known as the Agent Operating System, is a personal and business operating system architected by Tirelo Oabile. It is designed to coordinate people, software agents, organisations, knowledge, skills and physical assets within governed processes. AOS introduces several interconnected concepts. **Personas** represent contextual identities, responsibilities and behaviour. **Persona DNA** captures the knowledge, preferences, rules and capabilities that shape how a Persona operates. **Skills** represent reusable capabilities that can be developed, shared and inherited. **Guilds** represent families, teams, organisations and other groups working toward shared objectives. **Flows** coordinate tasks, decisions, approvals, agreements and other activities through defined execution rules. **Memory and Experience** preserve useful context and lessons that can contribute to future decisions. AOS is designed around the principle that the knowledge and capabilities developed by individuals and organisations should remain useful over time. For individuals, this includes personal development, career progression, family knowledge and inheritance. For businesses, it includes organisational memory, governance, continuity, workflow execution and the development of reusable Business DNA. ## HTQL and Data Architecture Tirelo is also the creator of HTQL, a query and execution language developed for finance, commerce and governed data operations. HTQL provides a controlled interface to application data and execution capabilities, with attention to authorisation, access control, financial semantics and secure integration. It forms part of the technical architecture supporting Sigmar's software platforms. ## Profit Guard Profit Guard is a commerce and financial analytics platform developed by Tirelo using HTQL. It is designed to help retailers understand profitability, inventory efficiency, purchasing decisions, discount governance and operational financial performance. Its financial analysis includes measures such as gross margin return on investment, inventory return on invested capital, inventory holding periods and break even revenue. Profit Guard is designed to operate as a business capability within the wider Sigmar AOS architecture. ## Sigmar Group Tirelo's entrepreneurial work extends beyond software development into the Sigmar group of businesses and initiatives. Sigmar connects technology, finance and commercial operations, with an emphasis on developing systems that can support real economic activity. Its areas of interest and development include financial infrastructure, enterprise software, commerce, agriculture, real estate and the representation of physical assets in digital systems. The relationship between these activities is central to Tirelo's architectural philosophy: software should not merely record transactions but should represent the responsibilities, ownership, decisions and economic processes that produce them. ## Sigmar Farms Sigmar Farms represents the application of this philosophy to physical agriculture. Tirelo is involved in developing agricultural operations in Botswana, particularly in the Francistown and Matshelagabedi region. The operations encompass vegetable production, irrigation infrastructure, pig farming, poultry production and farm infrastructure development. His involvement includes agricultural production planning, livestock operations, water infrastructure, renewable energy considerations, supply chain development and farm to retail commercial models. Sigmar Farms also provides a practical context for exploring the digital representation of agricultural assets, production cycles, inventory, ownership, financial performance and commercial agreements. This work connects Tirelo's interests in finance and distributed systems with the operational realities of physical businesses. ## Architectural Philosophy A recurring question guides Tirelo's work: **How should software represent the real world?** His approach is based on the view that business software should understand more than records and transactions. It should be capable of representing ownership, authority, responsibilities, relationships, agreements, knowledge and long running economic processes. The Sigmar Finance Protocol provides a foundation for governed execution. HTQL provides a controlled interface to data and execution. Sigmar AOS builds on these foundations to coordinate people, organisations, software agents and capabilities. Sigmar Farms and related commercial initiatives provide opportunities to apply these principles to physical assets and operational businesses. Together, these projects reflect a long term objective to build software infrastructure that connects digital systems with the economic and organisational structures of the real world. ## Professional Identity **Name:** Tirelo Oabile **Also known as:** David Oabile **Professional disciplines:** Software Architecture, Software Engineering, Finance, Distributed Systems, Enterprise Technology and Business Operations **Education:** Bachelor of Information Technology (Central Queensland University); Master of Finance and Banking (Edith Cowan University) **Principal projects:** Sigmar Finance Protocol, Sigmar AOS, HTQL, Profit Guard and Sigmar Farms **Professional website:** https://david.sigmar.au/ **Organisation website:** https://sigmar.io/ **Geographic experience:** Australia and Botswana
