Work

Designed and implemented the full purchase path for mutual funds and fixed deposits, driving over NGN 4.7 billion in investments.
Built the reporting system for accounts, transactions, orders and investments with a cross-functional team, making portfolio data queryable instead of requested.
Shipped portfolio dashboards that lifted user engagement and app usability by 70%.
Migrated data from an external MSSQL database to an internal PostgreSQL cluster — 30% better read/write performance and a schema that can actually grow.

Built a Lambda-powered generator for PDF/CSV transaction reports, improving insight delivery and lifting retention by 20%.
Rewrote client-side memory management, cutting application downtime by 80% under peak load.
Found and patched a critical vulnerability in the authentication system before it was exploited.

Led the complete Japanese-to-English translation of the application with i18next, opening it to thousands of global users.
Hardened recipe validation logic through rigorous testing, raising chef satisfaction by 20%.
Reworked UI components and layout for a consistent experience across device sizes.

Matching, profiles and messaging over a DRF API consumed by a React front end.
Capstone of the ALX backend specialisation — auth, permissions and relational modelling done properly.

Template engine over Django that composes policy documents from reusable clause blocks.
Export-ready output so non-technical teams stop editing Word files by hand.

Category budgets, expense capture and month-over-month tracking.
Started as a product requirements document — scope decided before implementation.

App Router build with typed data access and a component library shared across the surface.

Angular workspaces for the customer and back-office surfaces against a shared API.
One domain model, two very different sets of permissions.

Renders .splat and .ply captures in-browser on top of three.js and gaussian-splats-3d, with orbit controls and progressive load.
Falls back to <model-viewer> for conventional glTF assets so one URL handles both capture types.
Generates a QR code per scene for desktop-to-phone handoff — the whole point is looking at a capture on the device you're holding.
Built test-first: Red-Green-Refactor enforced across the Angular 19 workspace.

Flask server translates HTTP button presses into the Tello's UDP text protocol on port 8889 — the bridge a browser can't build itself.
Two-column cockpit: live camera feed with HUD overlay and photo gallery on the left, link status, battery, flight controls, telemetry and log on the right.
Handles the awkward reality that the drone's Wi-Fi has no internet — including flying it from a phone on the same network.
Collapses to a stacked layout on phones, because that is where you actually fly from.

Methodology-first recon and triage notes maintained per programme rather than one-off scanning.
Focus on authorisation bugs: IDOR chains, tenant isolation gaps, and logic flaws that scanners never see.
Findings written up as reproducible reports with impact framed for the receiving team.

Dynamic array, linked list, deque, BST, hash table, min-heap, graph, disjoint set, segment tree.
Insertion, merge and quick sort written and measured rather than imported.
