Develop and deploy backend APIs for interacting with Generative AI (GenAI) models
Build and manage secure authentication layers for AI-driven applications
Deploy and maintain containerized HashiCorp Vault instances for secure secrets management
Architected and led development of a production‑grade Conversational AI engine used to power products such as virtual call centers and automated customer interaction platforms
Designed the system as a layered architecture, comprising: o SIP ingress layer handling inbound and outbound calls o A dedicated call orchestrator that bridges SIP sessions to the engine’s WebSocket endpoints o Speech‑to‑Text (STT) ingestion for real‑time audio transcription o A RAG‑based context engine for domain‑aware knowledge retrieval o A reasoning and orchestration layer for intent resolution, workflow execution, and tool invocation o Text‑to‑Speech (TTS) voice synthesis for natural, low‑latency responses
Built scalable backend services to coordinate real‑time audio streaming, context enrichment, and response generation while maintaining reliability under high‑concurrency call sessions.
Developed a stablecoin‑based payment engine enabling low‑fee, near‑instant settlement for customer checkouts.
Researched and delivered a Web3 proof‑of‑concept for business registration using smart contracts and asset tokenization on the XRP Ledger.
Created scripts for data processing, task automation, and workflow optimization
Implemented internal file management systems for secure file sharing
Improved operational efficiency by ~38% through automation, better data visibility, and workflow optimization.
Designed and maintained an internal inventory management platform with real‑time analytics, admin endpoints, and automated weekly reporting.
Performed agricultural and market data analysis to support segmentation, forecasting, and weather‑driven decision making.
Led backend architecture for production-grade Data-as-a-Service (DaaS) and AI platform, achieving sub-100ms API response times under load
Designed specialized DaaS sub-product from scratch, handling 10,000+ concurrent requests with opGmized query planning and caching
Implemented NDPR-compliant security controls, authentication flows, and tenant isolation for enterprise clients
Collaborated with data science and product teams to expose scalable, analytics-ready APIs powering Al-driven insights and ML workflows
• Tech stack: Python, FastAPI, redis, OAUTH 2.0, postgresql, asyncpg, bcrypt, bloom filters • Designed production-grade, multi-tenant IAM platform providing secure authentication, authorization, and identity lifecycle management for SaaS applications • Implemented OAuth/OlDC-compliant authentication flows supporting PKCE, authorization codes, and refresh-token rotation • Built fine-grained authorization with RBAC, FGA, and ABAC-style policies, enforcing strict per-tenant isolation at application and database layers • Designed Redis-backed deterministic token revocation system using Bloom filters for 0(1) revocation checks with constant-time validation, avoiding per-request database calls or introspection endpoints while maintaining strong security guarantees where false positives result in forced re-authentication but never privilege escalation • Enforced strong tenant isolation using PostgreSQL Row-Level Security (RLS), enabling safe multi-tenant operation across shared infrastructure





• Tech Stack: Python, FastA PI, PostgreSQL, Redis, AWS S3, RAG, Docker • Architected multi-tenant Data-as-a-Service platform aggregating Nigerian and African datasets with market-place for dataset and ML/AI model monetization • Implemented RAG-powered business intelligence with real-time database connectivity for natural-language querying and insight generation • Built configurable, event-driven agentic workflows supporting data enrichment, compliance checks, analytics pipelines, and custom business logic with strict per-tenant isolation
• Tech stack: Python, FastAPI, RabbitMQ, Redis, Open-weight models (faster-whisper, piper-tts, chatterbox-ai, Mistral, Vicuna, Llama 3.2+), RAG, Refrag, postgresql, pgvector • Architected production-grade Conversational AI engine powering virtual call centers and automated customer interaction platforms • Designed layered architecture comprising: SIP ingress layer for call handling, call orchestrator bridging SIP sessions to engine's WebSocket endpoints, STT ingestion for real-time transcription, RAG-based context engine, reasoning/orchestration layer for intent resolution, and TTS voice synthesis • Built scalable backend services coordinating real-time audio streaming, context enrichment, and response generation under high-concurrency call sessions
• Tech Stack: Python, Streamlit, Prophet, XGBoost, Random Forest, Pandas • Built interactive dashboards integrating Prophet, XGBoost, and Random Forest models for time-series forecasting • Delivered real-time demand and inventory forecasts, enabling proactive inventory management and reduced stock-outs by 25%
• Tech Stack: Python, Streamlit, OpenAI API, FAISS • Developed Retrieval-Augmented Generation application enabling natural-language querying over domain-specific datasets • Delivered precise, context-aware answers by combining semantic retrieval with LLM-based reasoning
