ERP/HR extensions & dashboards

: React front-ends and Django/REST back-ends for modules like

Sites Setup

,

PMV Store

,

Asset Master

,

Breakdown Machinery

, user & password policy management, and bilingual (EN/AR) UIs integrated with

ePROMIS ERP (v16)

and

QuantumHR

.

Industrial fuel management

: Live telemetry, control and audit trails for pumps, solenoid valves and PODs; integrate microcontrollers/mini-PCs; design resilient offline/online data sync, logging, and analytics.

Identity & security

: Hardened authentication flows (policy, history, hashing), and future integrations with biometric devices (e.g., iris scanners) via secure APIs and encrypted storage.

Data & reporting

: MS SQL Server-backed APIs, stored procedures, and reports for operations, compliance, and finance.

What you'll do

Own features end-to-end: scope, design, implement, test, ship, and iterate.

Build clean

React

front-ends (Material UI / Tailwind) with solid state management and i18n (English/Arabic).

Develop secure

Django/DRF

services and occasional

Java

services where needed.

Design and optimize

MS SQL Server

schemas, queries, and stored procedures; review migrations and performance.

Integrate with third-party/legacy systems (ePROMIS, QuantumHR) and field devices (ESP32/industrial controllers).

Implement strong security: password policy, salted hashing, key rotation, audit logs, role- based access, and API hardening.

Ship production-grade CI/CD (Git), code reviews, and automated tests.

Translate business rules into reliable software and clear documentation for users and devs.

Must-have experience

6+ years

building production web apps used by real customers or internal teams.

Front-end:

React + modern tooling; component libraries; responsive, accessible UIs; form/state management; i18n.

Back-end:

Django/DRF (primary) and working

Java

experience (Spring or similar) for services/integration.

Database:

Microsoft SQL Server (schemas, indexes, views, stored procedures, performance tuning).

APIs & integration:

RESTful design, auth flows, secure data exchange, pagination, versioning.

Security:

Password hashing (PBKDF2/bcrypt/Argon2), password history/policies, OWASP awareness, input validation.

DevOps basics:

Git branching, code review, environment configs, logging/monitoring, and CI fundamentals.

Experience with

industrial/IoT

integrations (ESP32, Modbus, serial/TCP bridges, telemetry pipelines).

Bilingual UI patterns (EN/AR), RTL design competence.

Azure/AWS deployment, Docker, Nginx/Gunicorn, Windows Server/IIS exposure.

Reporting stacks (Power BI, Metabase) and scheduler/ETL experience.
