Based in Georgetown, Guyana. By day, senior systems engineering at Veridos; by night, building production software end to end — from database schema, to pixel-perfect UI, to the container it ships in. Multi-tenant marketplaces, full-stack platforms, mobile apps, and the infrastructure underneath all of it.

About
I'm a systems engineer out of Georgetown, Guyana, currently a Senior Engineer at Veridos — a global identity & security solutions provider — where I handle technical operations across a portfolio of production systems: escalation, root-cause analysis, deployments, and mentoring the next tier of engineers. Before that: seven years in telecom and network infrastructure, building IoT telemetry pipelines and SMS gateways, and getting hands-on with GPON, LTE, and microwave links on Guyana's national broadband rollout.
Outside the day job I build full-stack software end to end — schema design, backend logic, the UI on top of it, and the Docker/CI pipeline that ships it. Recent work spans a multi-tenant marketplace with real-time dispatch, a full-stack real estate platform with its own lead pipeline, a members' portal with role-based access, an offline-first point-of-sale, and premium marketing sites built to match a brand system exactly. Same approach every time: understand the real workflow first, then build the smallest system that handles it correctly. I'm also partway through an MSc in Information Security & Digital Forensics, which is less a career pivot than making official what the day job already demands.

Featured Work
Unified Guyana Market
Multi-tenant commerce & logistics platform
A four-sided marketplace built for the Guyanese market: shoppers, merchants, drivers, and platform operators, all coordinated through one real-time backend.
- ›Customer marketplace (React web + Flutter mobile) with wallet credit, gift cards, and coordinate-first delivery for addresses that don't fit a standard geocoder
- ›Merchant hub for multi-branch inventory, wholesale/weight-based pricing, and live revenue analytics
- ›Driver app with background GPS telemetry, OTP/signature/photo proof-of-delivery, and instant dispatch over WebSockets
- ›Admin console with live fleet tracking, wallet audit logs, and full actor lifecycle management
- ›Atomic stock deductions at checkout to prevent overselling under concurrent orders
District Grand Lodge of Guyana
Organization website & private members' portal
A public website plus a members-only portal for a long-established fraternal organization in Guyana, run day to day by non-technical staff through a CMS — notices, events and pages get published without a developer.
- ›Public site with a lodge directory, upcoming meetings shown in Guyana time, events, history, charity and leadership pages, news, site search, and an enquiry form that lands in a staff-only inbox
- ›Members-only notices and documents, scoped to the whole district or a single lodge, with pinned and expiring notices
- ›Role-based access (admin, editor, member): private files are served only after an access check, and the rules are pinned down by integration tests
- ›Photo gallery that is members-only by default — publishing a photo publicly requires explicit consent
- ›Deployed on Vercel + Supabase with migrations and seed data run on every build; the same stack runs locally in Docker
Paradigm Realty
Full-stack real estate platform
Property discovery and lead-gen platform for the Guyanese real estate market — map-first listings backed by a CMS and an automated inbox-to-lead pipeline.
- ›Map-based property search and listing pages built on Leaflet with a custom geocoding fallback
- ›In-house CMS (Tiptap-powered rich text) so listings and pages update without touching code
- ›Inbound leads parsed straight out of a shared mailbox via IMAP + mailparser, sanitized and routed automatically
- ›Web push notifications for time-sensitive listing and lead activity
- ›Image pipeline (Sharp) for consistent, fast-loading listing photos at every breakpoint
Charisma Group
Premium corporate website
Marketing site for a Caribbean-founded advisory firm working across sport, business, and investment — built to match an approved brand system down to the pixel.
- ›Full site build: Home, About, Services with four service drill-downs, Industries, Projects, and Contact
- ›Brand system implementation in burgundy / black / gold, with scroll-reveal micro-interactions throughout
- ›Enquiry form with a pluggable submission endpoint (Formspree-ready) and a safe mailto fallback
- ›Host-portable: ships as a multi-stage Docker build (Node → nginx) for self-managed hosting, and deploys the same on Vercel
GRB Complete Wheel Service
Marketing website for a Georgetown off-road & suspension shop
A fast, dependency-free marketing site for an off-road tyre and suspension shop — built around a WhatsApp-first quote flow instead of a web form, so leads land exactly where the shop already works.
- ›Custom SVG hero illustration of a pickup truck with a Stock/Lifted suspension toggle, done in pure CSS transforms with no animation library
- ›Signature topographic contour-line motif and scroll reveals built on IntersectionObserver + CSS only
- ›Stateless by design: no database and no mail server — the quote form opens WhatsApp with the message pre-written
- ›Photo-slot system so the owner's own photos can be dropped in later without touching code, with a stock-photo fallback that's labeled as such
- ›Host-portable through environment variables; ships as a Docker container behind Caddy on the same VPS pattern as this site, and also runs unmodified on Vercel
Barbershop Booking Platform
Appointment booking — customer web app + barber mobile app
Two Flutter apps on one Supabase backend: customers book through a step-by-step web wizard, and barbers run their day, their clients and their numbers from a mobile app.
- ›Customer booking wizard on the web; barber app with a live dashboard, client list, services and analytics
- ›Full appointment lifecycle with notifications, including a database trigger that fires the moment a barber marks themselves out of the shop
- ›Optional booking fees, loyalty points and discounts, plus availability rules with day-off exceptions and time-zone-correct scheduling
- ›Postgres Row-Level Security with security-definer helpers, and a trigger that stops users from editing their own role, approval status or loyalty balance
- ›Audit log covering sensitive changes
Retail Point-of-Sale System
Offline-first POS with inventory, invoicing & reporting
A point-of-sale system for a small retail shop that keeps trading when the internet doesn't: every device works against a local server on the shop network and syncs when it can.
- ›Mobile-friendly checkout with tax, discounts, loyalty-point redemption, refunds that restore stock, and invoices/receipts for every sale
- ›Inventory with auto-generated SKUs, low- and out-of-stock rules, suppliers and purchase orders
- ›Finance dashboard with KPIs and charts over any date range
- ›Push/pull sync with conflict rules per record type: sales are append-only, customers and products are last-write-wins, and stock stays server-authoritative
- ›Ships as a single Windows executable with an NSIS installer, plus an Android app via Capacitor — no cloud account required
LTE Site Power & Environment Telemetry
IoT monitoring pipeline for cellular infrastructure
Real-time monitoring for power and environmental conditions at LTE cellular sites on the Guyana National Broadband Project — built from a single-board computer up to the dashboard.
- ›Raspberry Pi as a Modbus master, reading power-generator telemetry off-site over the Modbus protocol
- ›Open-source IoT gateway (Eclipse Kura) publishing sensor and power data via MQTT
- ›Eclipse Kapua on the receiving end, fanning telemetry out for storage and analysis
- ›Grafana dashboards in the network operations center, with automated email alerts on anomalies
This Portfolio
Personal site — terminal-themed portfolio & interactive shell
The site you're on right now. A terminal/hacker-core personal site built to be a project in its own right, not just a list of them.
- ›Interactive shell with real commands (try 'help') and a Cmd/Ctrl+K command palette for fast navigation
- ›Live canvas network-graph background that waits for first paint before it ever touches the GPU, so it can't block load
- ›Full SEO pass — JSON-LD structured data, sitemap, robots, OG/Twitter cards — plus a 95+ Lighthouse score across the board
- ›3D-tilt project cards and scroll reveals, all hand-rolled with no animation library
- ›Shipped as a multi-stage Docker build to a self-managed VPS behind Caddy — the exact pattern used for the client sites above
