Things I've built
LiveFull-Stack · Freelance
Chrispo E.P.O Ltd: Hotel Web System
End-to-end full-stack system for a hotel client. Built a customer-facing booking and enquiry platform, a staff backend for managing reservations and generating receipts, and an admin dashboard with live analytics, booking history, and activity tracking. Handled full deployment, domain setup, and professional email configuration.
ProblemThe client had no digital presence; bookings were handled by phone and paper, making it impossible to track availability, generate reports, or manage staff efficiently.
ApproachConducted requirements sessions with the client to map all operational workflows. Designed the data model first, then built a modular REST API, followed by the customer-facing UI and the staff dashboard in parallel.
ChallengeNeeded a live admin dashboard showing booking activity and revenue without a dedicated analytics service. Solved with lightweight aggregation queries on the backend, cached and polled from the frontend on an interval.
OutcomeFull system live and in active use. Staff can manage all bookings, generate PDF receipts, and view analytics from any device. Client email and domain fully configured.

Chrispo E.P.O LTD: Real Estate & Pricing Analytics
Consulting engagement with a Ghanaian property firm. Analysed booking patterns across two short-stay properties, identified overpricing as the root cause of low occupancy, and delivered a data-driven repricing strategy. After the change the client reported a substantial revenue increase, with Barekese occupancy rising from 18% to 58%. Built end-to-end: Python EDA → Excel workbook → Power BI & Tableau dashboards → live interactive Plotly Dash app deployed on Render.
ProblemTwo short-stay properties launched at prices too high for the Kumasi market: Barekese at 18% occupancy, Buokrom at 15%. The client had no data infrastructure to diagnose why bookings were low or what the right price point should be.
ApproachStructured three years of raw booking records into clean datasets and ran full EDA in Python (Pandas, Matplotlib, Seaborn) to identify occupancy trends by pricing phase. Benchmarked against the local Kumasi market, built a phase-by-phase repricing model, and delivered findings through Power BI for operations management and Tableau for executive and investor reporting.
OutcomeBarekese occupancy rose from 18% to 58% after repricing and Buokrom from 15% to 61%, and the client reported a corresponding revenue increase across the repriced properties. All four portfolio locations across Ashanti and Greater Accra were analysed and delivered in a live Plotly Dash app and a structured Excel workbook.

Goal
Accessibility & Inclusion
Independent research project building a machine learning system to recognise and classify sign language gestures from image datasets. The system applies image preprocessing pipelines, feature extraction, and classification models trained on labelled gesture data, iterating on model accuracy and generalisation to work toward a real-world assistive tool for the deaf and hard-of-hearing community. Research combines computer vision techniques with accessibility-focused evaluation criteria.

Frederick delivered exactly what we needed, a complete web system, built and deployed from scratch, that our whole team uses every day. Professional, reliable, and genuinely understood what we were trying to achieve.

“
Working with Frederick was seamless from start to finish. He built us a website that genuinely represents our brand: professional, clean, and it just works. Our enquiries have gone up since we launched and our clients tell us it looks great. We couldn't be happier.
Frederick's work on GestureKey genuinely surprised me: the fact that it runs in a browser with no setup, detects hand gestures in real time, and is entirely his own build says a lot about what he's capable of. He doesn't just talk about building things, he actually ships them.

“
What stands out about Frederick's work is the breadth: full-stack systems, data analytics, AI research. When he showed me the portfolio I was impressed by how practical and production-ready everything looked. Someone who can go from a client brief to a live system independently is exactly what the industry needs.
Open to PhD and research positions, software engineering, data, and product roles.
I'm interested in PhD and research opportunities in AI and computer vision, and equally in engineering, data, and product teams where I can build across the stack, work with data, or take a product from brief to delivery. I work remotely and I'm open to relocation. Research collaborations welcome too.
