Skillas Marketplace System Design
Enhancial turned a demo-grade requirements document and a history of failed builds into a live, regulation-ready Nigerian gig economy marketplace with a complete governed system design.
The engagement at a glance.
System type
Multi-sided gig economy marketplace platform with regulated compliance
Starting point
A Business Requirements Specification that scored demo-grade on a formal maturity assessment, with prior build attempts that had not produced a stable, compliant system
Design scope
Produce a complete governed system design that makes the product buildable, auditable, and compliant under Nigerian regulatory standards
Main challenge
Turning a clear product vision into a structure that survives real-world pressure: payment disputes, compliance edge cases, API failures, and concurrent load
Outputs
Maturity diagnostic, 15-model system blueprint, full UI specification, compliance and verification programme, complete implementation packages
Status
Live at general availability, with ongoing governed amendment control
Where the project began.
Skillas arrived at Enhancial with a Business Requirements Specification that clearly defined what the platform needed to do, but lacked the architectural and governance specifications needed to build a reliable, auditable, and failure-tolerant system. A formal maturity diagnostic assessed the requirements against six architectural dimensions and returned a demo-grade score of 0.73 out of 4.0.
The diagnostic concluded that previous development attempts had likely failed, or produced fragile builds, for precisely this reason: the requirements were enough to build features that worked in a demo, but not the structure needed to prevent the system from breaking under real-world conditions such as payment disputes, compliance edge cases, third-party outages, or concurrent user load. The platform also had to operate as a regulated entity under Nigerian law, with obligations under data protection and anti-money-laundering regulations.
The design problem.
- User journeys were described in narrative but lacked defined stages, states, and transition rules, making consistent state management impossible
- User types were named but permission scopes, access boundaries, and interface contracts were undefined
- Regulatory obligations were not reflected in any design, leaving identity verification, AML workflow, and audit trails unspecified
- No logging, correlation, or operational alert model existed, making failed transactions impossible to reconstruct
- No designed behaviour for external API failures, stuck job states, or orphaned escrow transactions
What Enhancial did.
Enhancial reviewed the available materials, identified the architectural and governance gaps that had caused previous build attempts to fall short, and produced a complete governed system design that gave the team a reliable foundation for build. This included a formal maturity assessment, a 15-model unified system blueprint covering every layer of the platform, a full implementation package spanning requirements, technical design, QA, security, DevOps, deployment, release, and implementation planning, a dedicated verification and compliance programme with vendor research and regulatory sign-off, and a complete UI design specification with a design token system. Enhancial continues to govern the blueprint as the live platform evolves.
How the system was structured.
- Entry understanding
The engagement began with a scored maturity diagnostic of the requirements document across six architectural dimensions. It established a quantified baseline, identified the specific gaps behind previous build failures, and produced a roadmap toward trust-grade maturity.
- Evidence and requirement review
Enhancial reviewed all available materials and regulatory obligations, then structured them into the models required for a complete specification. A vendor research exercise evaluated 14 or more identity, KYC, and AML providers, and key decisions were structured into a management decision brief and signed off before implementation.
- System structuring
The complete unified system blueprint was produced across foundation, architecture, control, and experience layers, defining the system map, workflows, roles, data, integrations, governance, security, compliance, observability, and the full screen and journey set. Every specification traced back to a named source model and a documented decision.
- Design authority creation
A full UI design specification pack was produced alongside the blueprint, covering screen-by-screen interface logic, components, fields, interaction patterns, accessibility, and a complete design token system. A standalone verification and compliance programme defined the regulated identity, AML, and operations model.
- Readiness review
The implementation package was completed with zero gaps, confirmed by a capstone gap report, and a full developer handover pack was assembled with the blueprint, design specifications, 773 QA test cases, CI/CD specifications, and a production launch runbook. The platform launched at general availability, and Enhancial continues to govern post-launch amendments.
What was produced.
- Formal scored maturity diagnostic identifying six architectural and governance failure dimensions before build
- 15-model unified system blueprint covering architecture, control, and experience layers
- Complete stage and state machine for every entity lifecycle, including gigs, proposals, jobs, payments, and disputes
- Role-based access control model with 12 named roles and 153 permission test cases
- Complete data model, database schema, and migration design
- Full UI design specification across 67 screens and 20 user journeys with a design token system and accessibility requirements
- Verification and compliance programme aligned to Nigerian data protection and anti-money-laundering regulations
- Complete implementation packages and a vertical-slice sprint backlog, with 773 QA test cases and CI/CD specifications
- Ongoing governed blueprint amendment process for post-launch evolution
What the design made possible.
The governed system design gave the Skillas team something it did not have at the start of the engagement: a complete, unambiguous specification that any development team could implement without improvisation. The platform launched at general availability in the Nigerian market with a compliant identity verification programme, escrow-based payments, a fully defined multi-role admin and compliance system, and a regulatory posture aligned to national data protection and anti-money-laundering obligations.
The handover package was delivered with zero gaps and 773 QA test cases, and the access control model was fully defined and testable, eliminating the undifferentiated-admin risk present in earlier build attempts. Ongoing blueprint amendment governance means the design authority stays current as the platform evolves, rather than diverging from reality after launch day.
The capability behind the work.
- Enhancial can recover a product with a failed or fragile build history and produce a complete, immediately buildable design
- It can design a complex, multi-sided marketplace under demanding regulatory constraints
- It quantifies maturity and uses it to set a measurable improvement target, from demo-grade toward trust-grade
- It delivers complete, zero-gap implementation packages that a development team can build without improvisation
- It governs post-launch evolution, keeping the design authority current as the live system changes
Evidence and context.
- The platform is live and publicly accessible at getskillas.com
- It connects clients with verified service providers in the Nigerian market
- The project started from a Business Requirements Specification scored demo-grade at 0.73 out of 4.0
- Enhancial produced a 15-model system blueprint, full UI design specifications, and complete implementation packages
- The compliance programme was designed to meet national data protection and anti-money-laundering obligations, with a triple-match identity anchor
- The handover package was delivered with zero gaps and 773 QA test cases
