Architecture & Practices
Tech Stack Highlights
Lead Full Stack Developer
Ethiopian Artificial Intelligence Institute (EAII)
National Dialogue Digital Archive
- •Cut document retrieval time by ~80%, replacing paper-based workflows with a centralized digital archive of ~66,000 national dialogue records.
- •Improved query performance by 70% on large datasets through Elasticsearch full-text search, metadata indexing, and faceted filtering.
- •Unlocked natural language querying and automatic trend and anomaly detection across the archive by fine-tuning gpt-oss-20b into a domain-specific AI assistant.
- •Strengthened governance compliance and data protection with role-based access, authentication, authorization, and full audit logging.
Unified Platform
- •Consolidated multiple federal and regional organizations into a single zero-stop service, replacing fragmented per-organization systems.
- •Enabled SSO and role-based access across every integrated service via centralized identity management and event-driven communication.
- •Reduced onboarding a new organization from a code change to a configuration change with a configurable workflow engine.
Lead Developer & Full Stack Developer
Mesob Ethiopia
Human Resource Management System (HRMS) — Lead Developer
- •Cut server and infrastructure costs by 45% across 22 branches by consolidating HR, finance, and leave management onto one shared multi-tenant architecture, leading a team of 4 developers.
- •Guaranteed per-branch data privacy at scale through schema-based tenant isolation and tenant-aware storage.
- •Improved attendance accuracy by 90% and eliminated manual HR time tracking by integrating biometric attendance devices.
- •Hardened security, observability, and traffic management with centralized logging, single sign-on, and a Kubernetes-hosted API gateway.
Dynamic Dashboard — Multi-Tenant BI Platform
- •Removed engineering effort from every new dashboard request by letting non-developer admins build and share their own from 30+ drag-and-drop blocks.
- •Isolated each tenant's data across three permission tiers, so no organization can reach another's dashboards.
- •Kept analytics credentials off the client entirely by proxying Apache Superset server-side.
- •Made layout editing feel native with a Figma-style resize grid, undo/redo, and live-value sync, and reduced deployment to a single containerized command.
Queue Management System — Full Stack Developer
- •Reduced average customer wait times by 35% and raised peak-hour service throughput across 22 branches.
- •Accelerated cross-branch service coordination with real-time queue tracking and status updates.
- •Held performance and availability steady under high concurrency with scalable, tenant-isolated backend services.
ERP Full Stack Developer
Ethiopian Space Science Society
- •Reduced manual communication tasks by 40% by automating bulk and single letter generation and email notifications.
- •Improved operational efficiency by 35% by integrating new ERP functionality into existing business systems.
- •Removed hand-offs between back office and frontend by automating recurring workflows end to end.
Software Engineering Intern
Ethiopian Artificial Intelligence Institute
- •Improved code maintainability by 20% by applying Clean Architecture separation of concerns.
- •Reduced unauthorized access attempts by 30% with JWT authentication.
- •Cut query execution time by 40% through database query optimization.
Featured Projects
Multi-tenant BI platform with a drag-and-drop dashboard builder: admins compose dashboards from 30+ blocks — KPI cards, gauges, charts, tables and maps — on a Figma-style resize grid, then share them with role-scoped viewers. Keycloak-backed tenant isolation and Apache Superset data via a server-side proxy.
Real-time chat platform on a MERN + Flutter stack with fine-tuned NLP matching (all-MiniLM-L6-v2, 92% accuracy) and face-api.js face recognition. Improved case resolution time by 35%, reduced page load time by 28%, and boosted task throughput 50% with BullMQ and Redis.
Patient and Stock Management System for HIV care facilities, built on the MERN stack with drug control, disposal tracking, and room management modules. Optimized MongoDB and Mongoose queries for faster, more reliable hospital operations. Confidential solution under NDA.
Modular microservices architecture with role-based permissions. Built independent services for user management, event operations, and ticket handling with clean React + TypeScript frontend.
