Role-aware
Admin and super-admin paths with permissions, activity, and controlled approvals.
RBAC / audit trailFull-stack engineer / systems builder
I design and ship full-stack systems across payment infrastructure, marketplace integrations, and workflow-heavy products using Node.js, React, TypeScript, MySQL, Python, Django, and Go.
Product practice / across domains
The work I enjoy sits in the middle of a process: collect information, keep the right people in the loop, make the rules visible, and give someone a confident next action.
My through-line is simple: make the data, rules, and next action agree.
Admin and super-admin paths with permissions, activity, and controlled approvals.
RBAC / audit trailMulti-step intake for people, records, documents, review, and assessment.
state / transitionsDocuments and structured metrics stay attached to the record that created the decision.
files / validationWeighted scoring and analytics make the next action visible, not buried in a spreadsheet.
rules / reportingBuilt for the stack you are hiring for
I can move from the API contract to the interface, then carry the product through data, permissions, deployment, and applied ML.
Interfaces that make operational work understandable on desktop and mobile.
Python/Django, Go, and Node.js/Express services with explicit contracts, authentication, permissions, validation, and workflow transitions.
Relational models and durable records for people, files, metrics, and decisions.
Containerized deployments and repeatable delivery across the infrastructure a team already uses.
Three working MVPs / one systems practice
Open each product, use the seeded demo account, and test the primary workflow instead of reading a static case study.
React / Node / MySQL
Learning operations for institutions and enterprise training teams that need granular access, flexible grading, and clear progress reporting.
Target user Educational institutions, enterprise training coordinators, instructors, and students.
Core workflow Instructors define weighted quizzes, practicals, and exams; students submit coursework; the system calculates performance and renders role-specific views.
Built REST API, custom RBAC middleware, dynamic evaluation logic, and a React/Tailwind admin portal.
Technical decision Weighted evaluation runs through Celery and Redis workers instead of synchronous database queries, protecting the submission path during spikes.
Status Functional MVP deployed on AWS EC2 with GitHub Actions CI/CD.
React / Node / MySQL
Land and asset operations for project managers, surveyors, compliance teams, and evaluators working across fragmented evidence.
Target user Agricultural project managers, land surveyors, legal compliance teams, and real estate asset evaluators.
Core workflow Users onboard a parcel with DMS boundary points, attach legal and scientific documents, preview the boundary, and trigger assessment.
Built Relational geospatial schema, server-side DMS-to-GeoJSON conversion, AWS S3 document storage, and an interactive React map preview.
Technical decision A server-side coordinate transformer handles non-standard DMS input without depending on a paid external GIS API.
Status Live MVP with pre-loaded geographic data, interactive bounds, and document upload support.
React / Node / MySQL
Diligence operations for institutional investors, venture analysts, and project sponsors evaluating risk across capital pipelines.
Target user Institutional investors, venture analysts, and project sponsors assessing risk, compliance, and asset viability.
Core workflow Analysts filter portfolio assets by region, verification state, and submission source, inspect viability breakdowns, and export decision-ready summaries.
Built High-throughput REST API, optimized MySQL/PostgreSQL aggregation queries, and a responsive React dashboard with Recharts and Tailwind CSS.
Technical decision Materialized views and dynamic multi-column indexes keep multidimensional aggregations under 30ms.
Status Deployed MVP with interactive filtering, dynamic charts, and exportable reports.
Computer vision classifier for five skin-condition classes, exported to ONNX for lightweight inference and evaluated at 91.87% accuracy on an unseen test set.
Architecture Pre-trained ResNet18 fine-tuned with a custom five-class linear head and exported to ONNX.
Data Kaggle Skin Disease Classification dataset: Arsenic, Eczema, Melanoma, Normal, and Psoriasis.
Optimization Augmentation addressed class imbalance; Adam at 1e-4 preserved ImageNet features; constant folding and ONNX Runtime reduced CPU inference overhead.
Delivery Public Streamlit frontend with the model backend hosted on Hugging Face Spaces.
Logistic-regression model for stroke-risk estimation, tuned for recall on an imbalanced health dataset and served through a Dockerized FastAPI service.
Model Scikit-learn Logistic Regression tuned with C=35 and the liblinear solver.
Data Kaggle Stroke Prediction Dataset, with stroke cases representing only 4.8% of observations.
Evaluation ROC-AUC 0.8514 and F1 0.2973 after lowering the decision threshold to 0.09 to improve recall for positive cases.
Delivery Public repository with a Dockerized FastAPI inference service at api.stroke-predictor.acel.dev.
Chukwuemeka Aladimma / Lagos
I started with APIs and data systems, then kept moving closer to the people who use them. Today I build full-stack products where payments, permissions, records, and decisions have to agree.
View current resume ->Architected a payment bridge across Interswitch, OPay, Moniepoint, and Kuda POS terminals; built an initial Chowdeck marketplace integration; helped launch a customizable UI templating system that onboarded 6 new users; and shipped an OTP-authorized wallet that became the third most-used payment method.
Assumed sole backend responsibility by day two, supported mobile and frontend teams, resolved a critical production migration bug with preventative safeguards, and fixed a Docker storage anomaly that limited downtime to 3 hours instead of risking days.
Defined models, structure, coding standards, and testing methods for a greenfield system; led backend delivery across mobile, product, and engineering teams; and integrated AWS SNS for cross-platform push notifications.
Developed a custom Django lookup, refactored two sub-apps for clearer performance and analysis, and designed APIs and data clients for external integrations.
Spearheaded the 2024 bootcamp, graduating 37 students across 10 tracks from 360+ applicants; led pre-planning, curriculum design across 14 tracks, tutor recruitment, platform selection, graduation, and certificate issuance.
From brief to build
The first goal is not to build every screen. It is to make the core record move safely from intake to the next action.
Turn people, records, evidence, metrics, and roles into explicit domain objects and API contracts.
Build intake, review, assessment, and the first decision view end to end before widening the product.
Add validation, permissions, activity history, file handling, tests, and observable deployments around the workflow.
Use real operator feedback and usage data to decide which analytics, integrations, and admin controls come next.
Have a workflow worth improving?
Send the context, the constraints, and the decision the system needs to support. I will come back with a practical build path.
