Engineering Capabilities
From UI components to cloud infrastructure — organized by engineering domain, not a flat technology list.
End-to-end application development — from UI to database schema.
Scalable, secure APIs and service architecture.
Automated pipelines, containerization and deployment.
Infrastructure design and cloud resource management.
Designing systems that scale, survive, and are maintainable.
Integrating intelligent capabilities into production systems.
Each domain is applied together — not in isolation. A full-stack feature without observability, security, and a deployment pipeline is not production-ready.
Engineering Work
Production-oriented personal engineering projects. Each demonstrates real-world architecture decisions, not just feature implementation.
Scalable video-first learning infrastructure
A modular, multi-tenant e-learning platform supporting live courses, video-on-demand with HLS streaming, learner progress tracking, RBAC, payments, and AI-assisted content recommendations.
Key decision: Modular monolith over microservices — avoids distributed systems complexity at this scale
End-to-end travel operations platform
A comprehensive travel management platform connecting customers, travel agents, vendors, and staff with package booking, hotel reservations, payment processing, multi-currency support, and RBAC-protected dashboards.
Key decision: Optimistic locking on booking records — prevents race conditions during concurrent reservations
Production-grade institutional platform
A comprehensive school management platform serving students, teachers, parents, and administrators with attendance tracking, exam management, grade reporting, fee collection, and role-isolated dashboards.
Key decision: Clerk for headless auth — separation of auth concerns from application logic
Enterprise-grade stock and warehouse operations
A multi-warehouse inventory platform handling products, stock movements, purchase orders, supplier management, low-stock alerts, sales processing, audit logs, and analytics dashboards with RBAC.
Key decision: Immutable stock movement records — complete audit trail, supports reconciliation
Logistics and delivery operations system
A logistics platform for gas product ordering, delivery management, driver assignment, real-time delivery tracking, inventory management across branches, and customer/admin dashboards.
Key decision: Event-driven order state machine — clear lifecycle, easy to audit and extend
Umahaatu Khayrdoon — transparent giving infrastructure
A production-grade nonprofit donation management platform with campaign management, donor tracking, multi-currency payment processing, beneficiary management, automated receipts, audit logs, and RBAC-protected admin dashboard.
Key decision: Payment service isolation — financial logic separated from core domain for security
End-to-end event operations and ticketing
A scalable event management platform handling event creation, ticket types, attendee registration, QR code check-in, organizer/attendee dashboards, payment processing, and real-time analytics.
Key decision: Atomic ticket reservation with database transactions — prevents overselling under load
Real-time food delivery architecture
A multi-restaurant food ordering platform with restaurant management, menu configuration, customer ordering, driver assignment, real-time order tracking, payment processing, and dual dashboards for restaurants and admins.
Key decision: WebSocket gateway for real-time order status — customers see live updates without polling
All projects are personal engineering work and architecture studies. Let's discuss a production project together.
Bridging technical engineering and digital innovation to deliver scalable technology solutions.
Technology • Software • Digital Solutions
Company Founder
Suber Abdirsak Awil
Founder & Principal System Architect
Sifa Technologies is a technology company focused on building modern digital solutions, software systems, and technology-driven products that solve real-world business problems.
Under technical leadership, we engineer production-ready architectures, dependable software ecosystems, and high-performance digital platforms tailored to operational excellence and business growth.
Core Competencies & Services
Custom web applications, enterprise software architectures, and production-grade digital platforms.
End-to-end business automation, systems integration, and scalable technological infrastructure.
Modern cloud-native web systems built with performance, security, and scalability from the ground up.
Mission-critical architectures engineered for high availability, fault tolerance, and maintainability.
System Architecture
Systems designed for maintainability, scalability, and operational clarity — with documented reasoning behind every key decision.
Modular Monolith: Single deployable unit with clearly bounded internal modules. Preferred at early-to-mid scale where team size and traffic don't yet justify distributed complexity.
Modular Monolith
✓ Use when: Early-to-mid scale, small team, shared domain context, simpler ops
✗ Avoid when: When teams need independent deployment cycles per domain
Microservices
✓ Use when: High scale, large teams, domains with very different scaling needs
✗ Avoid when: Don't start here — distributed complexity requires operational maturity
Event-Driven
✓ Use when: Multiple downstream effects from a single business event (order, payment)
✗ Avoid when: When strong consistency between actions is required
Serverless
✓ Use when: Unpredictable, spiky traffic patterns; low baseline load
✗ Avoid when: Long-running workloads, complex orchestration, database-heavy apps
Engineering decisions with context, reasoning, and tradeoffs.
DevOps & Infrastructure
Automated pipelines, containerized environments, and cloud infrastructure — designed so software ships reliably every time.
Developer pushes to feature branch
ESLint + Prettier enforce code style
TypeScript compiler validates types
Jest runs unit and integration test suites
Next.js production build with optimizations
npm audit + dependency vulnerability check
Docker image built from multi-stage Dockerfile
Tagged image pushed to container registry
Rolling deployment to production environment
Liveness and readiness probes verified
Metrics, logs, traces, and alerts active
Fail Fast
Lint and type checks run first — cheapest to fix, fastest to catch. Tests run before build to avoid wasting compute.
Reproducible Builds
Docker multi-stage builds ensure the development, CI, and production environments are identical. No 'works on my machine'.
Security as a Gate
Dependency audits and vulnerability scans run in CI. Security issues block deployment, not just generate warnings.
Health-Verified Deployments
Deployments are only marked successful after liveness and readiness probes pass. Rollback triggers automatically on failure.
Secrets Never in Code
All secrets injected via environment variables at runtime. GitHub Actions secrets or AWS Parameter Store — never committed to the repository.
AWS
Vercel
Cloudflare
“You cannot operate what you cannot observe.”
Every deployed system should emit structured logs, expose metrics (Prometheus), support distributed tracing (OpenTelemetry), and alert on anomalies (Grafana / Sentry) — before it goes to production.
Engineering Philosophy
Technology decisions guided by principles — not trends. Click each card to expand the engineering practices behind it.
“The goal is not to write code. The goal is to solve problems in a way that doesn't create new ones.”
Engineering maturity is measured not by how many technologies you use, but by how well you understand the tradeoffs of the ones you choose.
Tech Stack
An organized view of the technologies I work with — with context on how each is applied.
TypeScript
Primary language — type safety across full-stack
JavaScript
Runtime language for Node.js and browser
SQL
PostgreSQL queries, migrations, and optimization
Python
Scripting, automation, and AI/ML integrations
Bash
Shell scripting for automation and CI/CD pipelines
40 technologies across 8 engineering domains — each selected for a specific reason, not because it was trending. The right tool for the right job.
Engineering Journey
A growth-focused timeline — from web fundamentals to system architecture and AI-powered systems. Each stage built deliberately on the last.
Growth Path
Started with the building blocks of the web — HTML, CSS, and JavaScript. Built static sites, learned how browsers render content, and developed an appreciation for clean, semantic markup and accessible design.
Adopted React as the UI layer and Node.js/Express for backend APIs. Learned component architecture, state management, REST API design, and how frontend and backend communicate through structured data contracts.
Went deeper into backend engineering: relational database design with PostgreSQL, authentication systems (JWT, OAuth, RBAC), caching strategies with Redis, background job processing, and building APIs that are secure, performant, and maintainable.
Adopted cloud infrastructure patterns: deploying applications to AWS, managing object storage and CDN for media delivery, understanding networking fundamentals, and designing infrastructure that scales horizontally.
Containerized applications with Docker for environment consistency, built automated CI/CD pipelines with GitHub Actions, and learned infrastructure automation — from health checks to rolling deployments and secrets management.
Began applying architectural thinking to system design: choosing between modular monoliths and microservices, designing event-driven workflows, implementing scalability patterns (caching, queues, connection pooling), and making reasoned tradeoffs.
Integrating AI capabilities into production systems: building LLM-powered features with OpenAI APIs, designing RAG pipelines for domain-specific knowledge, creating AI agents for automation workflows, and applying prompt engineering for reliable outputs.
Platform Engineering & Distributed Systems at Scale
