GROUNDED RAG & ADAPTIVE STUDY WORKSPACEFeatured Flagship

Lernivox

An engineer-led full-stack study workspace built across Next.js 15, NestJS 12, BullMQ, and PostgreSQL with pgvector. Combines a virtualized PDF.js/DOCX reader, 768-dim RAG retrieval with strict citation validation, worker cold-start wake handshakes, and spaced-repetition tools.

Grounded RAG tutor isolating untrusted chunks in strict delimiters and verifying [S#] citations against retrieved passages.
Authenticated /internal/wake and /readyz worker handshake queuing BullMQ ingestion jobs reliably on sleep-prone free-tier dynos.
Client-native virtualized reader built with pdfjs-dist, docx-preview, and TanStack Virtual for 400+ page text selection and citation jumps.

MULTI-BRANCH INVENTORY & POS LEDGER

Gelana

A production-grade, domain-driven retail platform engineered with React 19, Express 5, and PostgreSQL. Features an immutable double-entry stock ledger, deterministic row-ordering deadlock prevention for concurrent POS checkouts, real-time WAC valuation, and transit discrepancy isolation across distributed branches.

FULL-STACK SYSTEMS & EDITORIAL SHOWCASE

Portfolio v3

A flagship digital engineering showcase and deep-dive technical publication platform engineered with Next.js 15, TypeScript, and Motion. Combines tactile Swiss editorial aesthetics with rigorous full-stack systems: an in-memory session animation cache eliminating client route replay, a 220vh sticky process sequence governed by a 0.02 hysteresis margin, a mechanical keyboard switchboard with shared spring layout physics, and contract-first schema validation across a pnpm monorepo.

AI-POWERED CIVIC RELIEF & RAG PLATFORMAI & RAG

WeDonate

An enterprise-grade civic charity and social support platform engineered for the Adama City Administration in Oromia, Ethiopia. Built with React 19, Express, TypeScript, and PostgreSQL with pgvector. The platform features an intelligent AI chatbot powered by Google Gemini and Retrieval-Augmented Generation (RAG) acting as an on-demand civic concierge: it assists citizens by clarifying complex Kebele aid verification guidelines, guides donors through multi-channel bank and Telebirr payment reconciliation, and provides municipal administrators with automated case queue summaries and fraud-detection telemetry via role-partitioned vector queries.

E-COMMERCE & DEVICE REPAIR PORTAL

Gelana Stationary & Repair

A full-stack stationary retail storefront and laptop repair booking platform built with React 19, Vite 8, Express 5, and zero-ORM PostgreSQL. Unifies persistent database-backed carts, transactional checkout snapshots, purchase-verified reviews, stateful repair ticket triage, and trilingual (EN/AM/OM) SQL catalog resolution.

// How I build

Six steps from raw idea to shipped product.

A deliberate, end-to-end engineering sequence that keeps every architectural decision intentional, every dependency justified, and every release production-ready.

// DISCOVERY

Idea & Problem

Pinpoint who the user is and the exact friction they face. Strip away fluff to define the core value proposition.

↳A one-sentence problem statement

// SCOPE

Plan & Scope

Select the non-negotiable core capabilities and cut everything else to preserve speed and focus.

↳Scoped MVP feature list

// ARCHITECTURE

Interface & Flow

Map out data flows, page hierarchy, and touch states before writing frontend components.

↳Screen wireframes & user flows

// STACK

Architect Stack

Select backend frameworks, databases, and client state libraries justified by type safety and throughput.

↳Stack choice with rationale

// BUILD

Full-Stack Build

Model the database schema, write type-safe API routes, and construct high-fidelity UI with atomic Git commits.

↳Working app & repo on GitHub

// RELEASE

Ship & Refine

Audit Lighthouse scores, resolve edge cases, deploy to cloud edge servers, and benchmark live behavior.

↳Production URL & docs

// The stack

The stack I trust in production.

The languages, frameworks, and infrastructure I rely on to build scalable web applications. Point at a key, or tab across the board, to see duration and architectural rationale.

Three years, every line committed.

From writing my first lines of HTML and JavaScript three years ago to architecting full-stack applications with Next.js, NestJS, and PostgreSQL—now ready to ship for remote teams.
