• Own backend integration architecture supporting 10 AI providers and 99 AI models, designing reusable provider abstractions, standardized API contracts, model configurations, pricing logic, and error-handling workflows.
• Develop and maintain asynchronous AI generation workflows processing 1M+ generation jobs monthly, including task submission, execution tracking, retries, failure recovery, and integration with external inference services.
• Lead technical delivery across 4 engineers, driving architectural decisions, implementation planning, code reviews, engineering standards, and cross-team coordination for backend and AI-generation initiatives.
• Design and maintain backend security and access-control workflows involving OAuth, JWT authentication, authorization, credential management, third-party identity providers, and API integrations.
• Own production reliability and incident investigation across generation failures, provider limitations, subscription workflows, database performance, and asynchronous processing issues.
• Design and implement content-safety and retention workflows, including moderation, controlled access to mature content, scheduled cleanup, and automated data deletion processes.
• Collaborate with product, legal, support, safety, and finance stakeholders to translate complex requirements into secure, maintainable backend features.

Full Stack Engineer / Technical Lead

Accra, Ghana

• Led the design and development of the backend architecture for a logistics and fleet-management platform that has supported over 73,000 registered users, 689,000 deliveries, and 1,400 vehicles, covering dispatch, real-time tracking, merchant integrations, and operational analytics.
• Architected and maintained AWS-based infrastructure using Elastic Beanstalk, API Gateway, Lambda, CloudWatch, and MongoDB Atlas, supporting a production platform handling over 600,000 API requests per month.
• Designed and developed a multi-service fleet-tracking architecture separating GPS telemetry ingestion and processing in Go from customer-facing Node.js APIs, using MongoDB for telemetry storage and enabling real-time vehicle tracking across applications.
• Designed REST APIs and external integrations connecting payment providers, logistics partners, merchants, tracking systems, and client applications through webhooks and third-party services.
• Implemented reliable background processing and integration workflows using retry mechanisms, idempotency controls, and failure recovery to improve resilience when processing external requests and system events.
• Designed and implemented backend security controls using OAuth, JWT validation, role-based access control, credential management, and AWS IAM policies to protect API endpoints, restrict access to services, and secure infrastructure resources.
• Improved application performance and reliability through MongoDB indexing, query optimization, aggregation pipelines, infrastructure monitoring, and production debugging.
• Owned backend architectural decisions and technical implementation planning, conducted code reviews, mentored engineers, maintained technical documentation, and guided engineering teams on system design and production delivery.

Software Engineer

• Delivered production web applications and APIs for startups, owning the lifecycle from architecture and development to deployment.
• Built backend services, dashboards, and third-party API integrations across SaaS and commerce products.
