A statistical sampling framework for estimating onion seedling density in data-scarce smallholder farming systems in Pwalugu, Upper East Region of Ghana. Using field observations from a two-acre farm and the Central Limit Theorem, the work estimates mean planting density and quantifies variability in manual transplanting practices — providing a practical, low-cost planning model for seedling requirements based on effective bed area.

A peer-reviewed research article published in an academic journal indexed in NASA ADS. Contribution forms part of a collaborative research effort spanning data analysis and computational modeling within the study domain.

A mobile-first group contribution wallet platform built for communities, churches, committees, and individuals who need a simple, trusted way to collect and manage contributions. Supports mobile money payments via USSD and QR, transparent contribution tracking, and public or access-code-protected wallets — eliminating spreadsheets and manual tracking.

A synthetic data generation platform for researchers, students, and analysts who need documented, defensible datasets when real data is scarce, restricted, or doesn’t exist yet. Each domain is its own "line family" with a documented rationale behind every field, its own hypothesis table, and its own methodology page. Every dataset is fully deterministic — seed, config, and generator version always reproduce the same output byte-for-byte — and ships with a manifest, checksum, data dictionary, and a ready-made citation block (APA/MLA/Chicago/BibTeX).

A business website built for Reigneth Company Limited, a Cash-in-Transit (CIT) solutions provider, general merchant, and office equipment supplier serving banks and businesses across Ghana. Presents the company’s product lines — shrink wrap machines, banknote banding machines, and coin counting machines — alongside their installation, repair, and maintenance services, company info, and downloadable equipment spec sheets.

A newly developed business platform for Tim Supply. Designed to present the company’s products and services with a clean, professional web presence.

A clean, professional personal portfolio and CV site built for Timothy Azirigo, a logistics and transport management professional based in Accra, Ghana. Presents his career profile, work history spanning operations management, logistics, and procurement, educational background including an MBA from GIMPA, professional certificates, and a downloadable CV.

A professional business website designed and developed for Renoval Solutions. Built as a static site and hosted on GitHub Pages, showcasing the company’s services, portfolio, and contact information.

Platform site for Yenko WiFi, an internet service provider project. Designed to communicate service offerings, coverage, and subscription details to prospective customers.

Implements the T3Clus and 3FKMeans iterative techniques for simultaneously clustering objects and reducing the dimensionality of variables and occasions on three-mode datasets (Vichi et al., 2007), plus a convex combination of the two — CT3Clus — governed by a hyperparameter α ∈ [0,1] (3FKMeans at α=0, T3Clus at α=1). Also implements the traditional tandem procedures TWCFTA and TWFCTA (Arabie & Hubert, 1996) for sequential clustering-factorial decomposition.

As the creator of The Addon Forge, high-performance browser extensions focused on web automation, productivity enhancement, and media extraction — emphasizing clean engineering, user-centered design, and seamless cross-browser compatibility.

A case study on improving National Health Insurance Scheme (NHIS) coverage in the Sunyani municipality, using the Contingent Valuation Method (CVM) to estimate individuals’ Willingness To Pay (WTP) for extended coverage. Binary Logit Regression, including a social interaction term, identified factors influencing the decision to pay. Findings showed most NHIS holders who purchase additional drugs were willing to pay for extended coverage — most notably for rehabilitation, cancer, and heart-related conditions, averaging up to GH₵30.00/year — and recommended policymakers weigh income, gender, and education in coverage decisions.

Developed and implemented five models — TWCFTA, TWFCTA, T3Clus, 3FKMeans, and CT3Clus — in the simuclustfactor packages (Python and R) for analyzing three-mode datasets, proposed by Vichi et al. (2007) as an alternative to traditional tandem models. Tested on synthetic and real datasets, the simultaneous models produced more well-separated, higher-cohesion clusters and better recovered object-cluster and variable/occasion-factor associations than tandem models, with the best results obtained when factorial analysis was prioritized.
