Hi, my name is

Louis Marie Atoluko Ayariga.I build systems others overlook.

I’m a full-stack developer, AWS cloud developer and African Union Digital Innovation Fellow. I design and build reliable, scalable software — for institutions and businesses that need a proper system, delivered from brief to production, at a global standard.

01 · About

Design before build.

My path into engineering started at a Wazihub IoT bootcamp in 2018, ran through a BSc in Computer Engineering at KNUST, and led to a Tech Fellowship with the African Union’s human-rights commission. Today I run Loumar Consultancy and lead front-end delivery at a UK virtual-assistant agency.

I work across the whole stack — React and Next.js on the front, Node, Nest and PostgreSQL on the back, AWS underneath — and I design the product too, from research and wireframes to full UI/UX in Figma. I’m comfortable leading a project from a client brief to a deployed, maintainable system.

I believe in designing every screen before writing code, in delivering module by module so clients see value early, and in being honest about AI — I use it to move faster, but it doesn’t replace architecture, security, testing or accountability.

Selected work, in depth.

Designing 94 pages before writing a line of code

QPA Virtual Assistants (UK)

Problem. A UK virtual-assistant agency was running operations across disconnected tools — staff management, client onboarding, time tracking and payroll all lived in different places, with no shared source of truth and no permission model.

Approach. I led the full design phase before any code: a complete 94-page UI/UX design covering 10 functional modules and a 7-role, multi-role permission system. I built the design system end to end — colour tokens, Poppins + DM Sans typography, a component library, 8 shell variants and 10 transactional email templates — plus external client-facing onboarding and feedback screens.

Outcome. A build-ready blueprint: a role-based permission matrix (up to 4 roles per user), a client → project → VA assignment model, a 5-metric performance scoring system with rolling 12-month averages, a 7-phase onboarding checklist and a live timer to replace Toggl — GDPR-conscious by construction. The design has since been approved, and I've been engaged to build it: development starts September 2026 on Next.js, Node/Express, PostgreSQL and Vercel + Railway.

Closing an approval loop that trapped NGOs for years

African Commission on Human & Peoples' Rights (African Union)

Problem. The African Commission grants NGOs observer status and coordinates with National Human Rights Institutions across the African Union's 55 member states — but the whole process ran on email and a single Word document. Applicants had no structured way to know what to submit, so incomplete applications bounced back again and again; and because some supporting documents take months to assemble, organisations got caught in loops that stretched a process meant to take three months into several years. Reports of human rights abuses arrived the same way — a buried email, a WhatsApp message, a call to whoever you happened to know — so urgent cases could sit unanswered long after they were raised.

Approach. As a Tech Fellow at the African Union, I proposed and led a platform that restructured three broken flows: a guided application intake, so an organisation submits only once it has everything and gets a human review with clear feedback instead of silent rejection; a living repository of NGO and NHRI records that the organisations themselves keep current; and a reporting channel that accepts anonymous submissions and alerts the Commission the moment an abuse report arrives.

Outcome. The design closes the loop that had trapped applicants for years — structured intake and review keep observer-status decisions inside their intended three-month window — while giving the Commission a single, current source of truth for its network and a direct, alerting path for human rights reports. I built the platform and handed it over to the Commission at the end of my fellowship. The work received the AfriLabs Award at the 2022 Annual Gathering in Lusaka.

A live platform for 700+ parishioners

Our Lady Queen of Africa Parish, Bolgatanga

Problem. A growing Catholic parish needed a proper digital presence and a way to manage a large, active community rather than relying on ad-hoc communication.

Approach. I designed and built the platform end to end on Next.js, Nest.js, PostgreSQL and Prisma in TypeScript — from information architecture through to a deployed, maintainable production system.

Outcome. A live platform now managing 700+ active parishioners, running in production and maintained over time — a real example of taking a community from no system to a dependable one.

Field research · ECOWAS Youth Consultation, Northern Ghana (2024)

The problem wasn't a skills gap. It was a fairness gap.

Co-facilitating ECOWAS-commissioned youth consultations across Upper East and North East Ghana — structured focus groups stratified across unemployed graduates, apprentices, public and private sector workers, small-scale miners, persons with disabilities, migrants and youth leaders — one theme dominated every site: educated, trained young people who couldn't access jobs without political connections or bribes, and a sense that investment concentrates in the south while the north is overlooked. I led the team, including youth participants, that presented the findings to ECOWAS in Accra.
