Delivered backend architecture, APIs, PostgreSQL schemas, Redis caching and VPS deployment for the Ahoto healthcare and logistics ecosystem; supported four iOS and four Android releases and worked directly with product stakeholders through production issues.. Built an AI interview-intelligence and career-readiness platform as a freelance engineer using FastAPI, React, TypeScript, MongoDB, RAG and multiple model providers; own architecture, retrieval quality, model integration, deployment and ongoing product changes.. Designed service architecture and data models for a diaspora marketplace covering merchants, inventory, orders, payments, delivery and fulfilment; defined API, integrity and integration standards for a fully remote team.. Translated lead-research and competitor-analysis workflows into an AI-assisted product with FastAPI, SQL, React and LLM extraction; built a seven-stage pipeline with validation, lineage, retries, quarantine and targeted reprocessing.. Built and deployed a responsive website and CMS interface remotely, replacing a developer-dependent content workflow with direct publishing for non-technical staff.. Built Node.js services, access controls, transaction workflows and VPS deployment for an airtime-and-data distribution platform that processed more than 100,000 secure transactions with no recorded security incident.

Built distributed Python services, model APIs and financial-data pipelines for a commodity-trading and market-intelligence platform.. Took LSTM and Hidden Markov Model workflows through data preparation, training, validation, deployment, monitoring and production debugging.. Investigated failures across data, models and backend services, then changed implementation and architecture where reliability or performance broke under real operating conditions.

Delivered custom software for startups, businesses and innovation programmes, covering APIs, databases, web systems and AI features.. Built Afia AI using NLP, RAG and LLM integrations, and developed predictive analytics for venture-capital assessment using Python, Pandas, Scikit-learn and SQL.. Supported architecture, debugging, deployment and technical mentoring across client and community projects.

Supported users directly across workstations, Windows systems, printers, networks, accounts and business applications in a security-controlled environment.. Diagnosed problems with incomplete information and limited access; maintained backups, access controls, antivirus, equipment records and incident documentation under military procedure.

Provided frontline technical support, resolved hardware and software incidents, carried out routine maintenance and kept shared systems usable for daily business operations.. Worked directly with users who described problems in business terms, traced the technical cause and applied practical fixes or escalation steps.

Built application logic, REST APIs and integration layers for a microservices campus-navigation platform; optimised database access and wrote API documentation for maintenance and handover.

Managed Linux and Windows systems, user access, networks, backups and production services across several years of day-to-day operations.. Automated recurring administration and monitoring work in Python and implemented backup and recovery controls.

Performed authorised security assessments using Kali Linux, Wireshark, Shodan and custom Python tooling; documented vulnerabilities and practical remediation steps for clients.

Independent engineering engagements spanning AI/ML engineering, agentic systems, AI data pipelines, backend architecture, distributed systems and production software. Work with clients and remote teams from requirements and architecture through implementation, deployment, debugging, documentation and technical delivery.

Designed and implemented a multi-tenant architecture supporting multiple organizations, services and operational workflows.. Designed and implemented a microservice architecture for scalable service separation and independent deployment.. Architected backend services, APIs, PostgreSQL schemas and distributed service workflows.. Implemented Apache Kafka for asynchronous service communication and distributed workflows.. Implemented Redis for caching and performance optimization.. Configured NGINX as reverse proxy and load-balancing infrastructure.. Prepared, configured and maintained VPS infrastructure for production deployments.. Containerized services using Docker for deployment consistency and service isolation.. Used Git/GitHub for version control and structured engineering workflows.. Implemented webhook-driven integrations and backend service communication.. Built internal administration and management tools supporting business and operational workflows.. Developed an Electron.js pharmacy-management application for the AhotoCare ecosystem.. Contributed to the development and release of four iOS and four Android applications across the wider AhotoPlatforms ecosystem.. Worked directly with stakeholders to translate operational requirements into production systems.. Diagnosed production issues across application, infrastructure, database and service layers.. Designed the software and infrastructure foundation required for AI-enabled and data-intensive business systems.

Designed and built Bufalo AI as an AI-assisted sales and marketing intelligence system.. Converted lead-research, prospecting and competitor-analysis workflows into an automated AI/data-processing system.. Designed a multi-stage pipeline covering data acquisition, extraction, cleaning, validation, lineage, retries, quarantine and targeted reprocessing.. Integrated LLM-based information extraction into structured business-data workflows.. Automated recurring data-gathering and cleaning activities that previously consumed approximately four days of the working week.. Helped increase effective sales and marketing team output by approximately 4× through workflow automation.. Built backend and data-processing components using Python, FastAPI, SQL, React and LLM integrations.. Designed the pipeline around data quality, validation and traceability, rather than treating raw LLM output as inherently reliable.. Applied AI/data engineering principles to transform unstructured external information into usable business intelligence.

Built an AI interview-intelligence and career-readiness platform using FastAPI, React, TypeScript, MongoDB, RAG and multiple model providers.. Designed AI application architecture and retrieval workflows.. Integrated multiple LLM providers and implemented model/application orchestration.. Worked on retrieval quality, AI response quality and production reliability.. Owned architecture, implementation, deployment and ongoing product improvements.

Built distributed Python services, model APIs and financial-data pipelines for a commodity-trading and market-intelligence platform.. Developed machine-learning workflows using LSTM and Hidden Markov Models.. Took ML workflows through data preparation, training, validation, deployment, monitoring and production debugging..
