CAREER TRAJECTORY & IMPACT
Professional Experience
3+ years architecting access-controlled APIs, double-entry financial ledgers, and distributed systems—consistently maintaining 99.9% uptime and high financial integrity.
Architected the unified commercial super-app backend and server architecture for Zimbabwe, powering marketplace commerce, service directories, job listings, and municipal utility bill settlements with high-concurrency Node.js and Next.js 14 server routes.
Key Responsibilities & Deliverables
- Engineered custom JWT token family rotation with sliding refresh mechanics, mitigating token theft and securing continuous user sessions.
- Designed scalable multi-tenant PostgreSQL schemas with Knex connection pooling and granular Supabase Row-Level Security (RLS) policies.
- Constructed high-throughput transactional APIs for multi-category marketplace orders, applicant pipelines, and municipal bill payments.
- Built automated transactional email delivery pipelines using Resend, ensuring sub-second delivery for verification codes and receipts.
Designed and implemented the core financial engine, double-entry ledger, and real-time matchmaking backend in Node.js/TypeScript, bridging seamless Web2 onboarding with multi-chain USDC settlement.
Key Responsibilities & Deliverables
- Engineered an append-only double-entry ledger in micro-USDC protected by PostgreSQL row-level locking (SELECT ... FOR UPDATE) to eliminate race conditions and double-spending.
- Constructed dual-layer zero-gas deposit verification: Layer 1 inbound Blink HMAC webhook + Layer 2 read-only direct RPC verification to confirm transaction receipt before ledger crediting.
- Architected white-labeled Azza fiat on-ramp generating in-app Nigerian virtual bank details for instant Naira-to-USDC conversion.
- Implemented WebSocket matchmaking and escrow mechanics with 95% winner payout and 5% platform rake, integrated with an authoritative 100Hz headless game server.
Architected and deployed a modular, high-availability REST backend in Node.js 20 and Express/TypeScript for a faith-based mental health platform, ensuring HIPAA-grade privacy and low-latency response times.
Key Responsibilities & Deliverables
- Implemented secure dual-token authentication (short-lived access + sliding refresh) with automatic revocation in Redis 7.
- Reduced average endpoint response latency from 180ms to 24ms for cached resources via Redis 7 query caching.
- Designed normalized PostgreSQL 16 database schemas with Knex migrations and strict foreign-key integrity constraints.
- Configured Docker containerization, PM2 process management, and automated continuous deployment pipelines on Render.
Built Monevo, a voice-first WhatsApp financial assistant for African micro-merchants, enabling instant bookkeeping via English and Nigerian Pidgin voice notes.
Key Responsibilities & Deliverables
- Integrated AssemblyAI speech-to-text pipeline with prompt engineering tuned for colloquial West African trade and accounting terms.
- Engineered fast LLM intent extraction using Groq (Llama 3.3) with Claude 3.5 fallback, classifying income, expense, and debt under 500ms.
- Created dynamic image generation service with Sharp rendering branded SVG receipts and weekly spending graphs directly inside WhatsApp.
- Deployed resilient production webhook architecture on Railway with Kapso integration and HMAC authentication.
Built a high-performance Python FastAPI AI microservice coupled with a PHP/MySQL multi-tenant CRM backend to automate customer outreach, scoring, and workflow intelligence.
Key Responsibilities & Deliverables
- Engineered an internal loopback FastAPI microservice running Miss Algorithm—an AI co-pilot for automated lead engagement and anti-cheat verification.
- Secured microservice communications behind a PHP 8 API gateway enforcing OWASP security baselines, CORS whitelisting, and JWT RBAC.
- Designed and implemented high-volume customer data import/export routines handling thousands of records with database transactional integrity.
Architected high-integrity examination delivery systems, candidate management, and automated scoring backends using Python and Django REST Framework.
Key Responsibilities & Deliverables
- Implemented JWT authentication and fine-grained Role-Based Access Control (RBAC), strictly enforcing least-privilege permissions across examination candidate and proctor roles.
- Designed scalable PostgreSQL schemas and custom user models with database-level data integrity constraints.
- Collaborated cross-functionally with frontend engineers to ship reliable, well-specified API contracts.
- Deployed and maintained production infrastructure on Render and Vercel, sustaining 99.9% uptime across peak exam delivery windows.
