About Me
Who I Am
I'm a Senior Backend Engineer and AI Engineer with 4+ years of experience designing, building, and scaling production-grade systems across fintech, healthcare, government, gaming, and education verticals. I've delivered 13+ production and in-progress systems — spanning RESTful APIs, real-time WebSocket servers, AI proctoring pipelines, and RAG-based LLM agents — serving government agencies, NGOs, universities, and startups.
I build server-side applications using Python (FastAPI, Django), PHP (Laravel, OpenSwoole), and JavaScript (Node.js, Express.js). Beyond traditional backend development, I work at the intersection of software engineering and artificial intelligence — building computer vision pipelines with YOLO and MediaPipe, voice activity detection with Silero VAD, and LLM-powered systems leveraging RAG architectures, LlamaIndex, and Qdrant.
Known for production-grade practices: immutable ledgers, pessimistic concurrency control, dual-layer audit systems, and event-driven architectures with durable execution. Sound engineer at Apostolic Faith Church since 2015 — demonstrating sustained commitment and technical discipline beyond software.

Featured Projects
13+ production systems delivered across fintech, healthcare, government, gaming, and education.
TRCN AI Proctoring System
Bluespectra Limited
Built production real-time proctoring service detecting 6 violation types (face absence, gaze deviation, multiple persons, phone usage, speech, background noise) via server-side WebRTC stream analysis. Implemented adaptive per-candidate RMS noise baseline calibration, thread-safe session store with 10-min TTL, and singleton model loading eliminating 2–5s cold-start penalty. Containerized for CPU-only deployment with ~2–4GB memory footprint.
TRCN AI Lesson Note Agent
Bluespectra Limited
Architected event-driven RAG pipeline: document ingestion → SentenceSplitter chunking (700 tokens / 100 overlap) → OpenAI embeddings → Qdrant with payload indices on 4 educational metadata fields for pre-filtered similarity search. Reduced repeated LLM inference by ~60% through DB-backed answer caching. Inngest durable functions handle retries and observability. Multi-format document ingestion (PDF, DOCX, HTML, URL).
Telcom API — Veritob Wallet Platform
Private Contract
Built immutable double-entry financial ledger with balance snapshots (balance_before/balance_after) on every transaction. Implemented HMAC-SHA256 webhook verification, single-use PIN session tokens consumed atomically before purchase, and event-driven virtual account provisioning with exponential backoff retries. Applied UUID v7 primary keys and composite indexes on hot query paths.
FPI Clinic API — Hospital Information System
Zealarax Technologies
Sole developer of a 371-action, 62-model, 96-migration modular monolith covering the full hospital clinical lifecycle with polymorphic InPatient/OutPatient clinical data via 28 polymorphic relationships. Implemented pessimistic locking at 6 resource contention points and an 11-point leave validation engine with fiscal-year carry-over. Designed dual-layer audit: Spatie Activitylog on 60+ models + custom AuditObserver.
OGSHC Housing Management System
Bluespectra Limited
Delivered end-to-end property and payment management platform for Ogun State Housing Corporation with 4 payment channels, 85+ granular RBAC permissions across 4 roles, and dual authentication guards (admin password-based + customer OTP-based). Implemented Paystack charge abstraction enabling future gateway swaps without code changes. Comprehensive audit trail with IP/browser/request context capture.
Zamfara Drug & Medical Supply Chain API
Zealarax Technologies
Designed multi-supplier PO workflow with atomic approval/rejection: approving one supplier's quote atomically rejects all competing POs in a single Sequelize transaction. Built transactional POS with VAT (inclusive/exclusive), percentage/fixed discounts, parallel inventory decrement via Promise.all, low-stock alert triggers, and dual observability with JSON diffs.
Ludo Game WebSocket Server
Bluespectra Limited
Built stateful real-time WebSocket server using OpenSwoole with 3 in-process shared memory tables eliminating Redis dependency. Supports 1,024 concurrent connections and 256 game rooms with O(1) state reads. Two-layer API authentication (developer access key + session token), per-key API call analytics, and DB connection health probe for long-running process resilience.
EMS-IBR — Examination Management System
Co-owned · Federal Polytechnic Ilaro
Co-designed multi-pass constraint-satisfaction seat allocation algorithm (checkerboard/diagonal pattern-based + random fallback with 500 attempts) enforcing 8-directional adjacency constraints to prevent academic dishonesty. Celery async job system with BackgroundJob model tracking progress, status, and full traceback storage. Currently deployed for institutional testing.
OAU Amaranthus Virtual Assistant
Zealarax / Bluespectra
Architected database-first Q&A system with DB-backed multilingual answer cache (English, Yoruba, Igbo, Hausa, Nigerian Pidgin) — reducing average response latency by ~60–70% and lowering repeat OpenAI API calls by ~50–65% over time. Implemented keyword-based domain guard (~190 amaranth-specific keywords across 5 languages) as pre-filter before GPT inference.
Dynamic Content-Driven Website Backends
Zealarax Technologies
Delivered generalized API-first CMS backends for NCECC (Nigerian-Central Europe Chamber of Commerce) and RTI (Regional Trade Institute) — 30+ content entities per system with RBAC, paginated public APIs, Paystack checkout, and OTP-based authentication flows. Diagnosed and resolved critical technical debt across inherited codebases.
Timetable & Seating Allocation Optimizer
Academic Research Project
Implemented constraint satisfaction algorithms to minimize scheduling conflicts and optimize hall/seating allocation for educational institutions, forming the algorithmic foundation for EMS-IBR. Full-stack research prototype with dynamic visualization.
Agent-based Coding Skill Assessor
Academic Project
Led development of an agent-based system performing automated real-time code evaluation — analyzing efficiency, correctness, and coding standard adherence using Python's AST module with detailed automated reports and scoring engine.

What People Say
Feedback from colleagues, clients, and collaborators I've had the privilege of working with.
Fortunatus has a remarkable ability to architect complex backend systems with a level of precision that's rare. His work on the TRCN AI proctoring system and the Ludo WebSocket server demonstrated deep technical thinking — from concurrency handling to production optimization. He consistently delivers solutions that are both robust and elegantly engineered.
Working with Fortunatus on the FPI Clinic API and the Zamfara Drug Supply Chain was exceptional. He inherited complex codebases and not only resolved critical technical debt but also redesigned systemic components — polymorphic models, pessimistic locking, multi-supplier transaction handling. He's proactive, thorough, and a pleasure to collaborate with.
Fortunatus built the entire Telcom API platform for Veritob from scratch. The double-entry ledger, webhook verification, and PIN security system he designed gave us complete confidence in financial transaction integrity. He understood our business needs deeply and translated them into a secure, scalable system that just works.
As a researcher at Federal Polytechnic Ilaro, I observed Fortunatus's exceptional problem-solving skills during the timetable and examination management system projects. His constraint-satisfaction algorithms for seat allocation demonstrated both algorithmic depth and real-world applicability. He bridges the gap between academic rigor and production engineering remarkably well.
Co-owning EMS-IBR with Fortunatus has been an incredible experience. His backend architecture decisions — the Celery async pipeline, the constraint-satisfaction seat allocation engine, the dual audit system — elevated the entire project. He approaches every problem with deep systems thinking and delivers code that's truly production-grade.
