Hi, I'm Ibrahim
A Software Engineer & Full-Stack Developer
What I have done so far
Education & Experience.
Software Engineer
Telnet
- Implemented C++ design patterns (Factory, Observer, Iterator, Strategy) to modularize payment-terminal firmware, improving maintainability and enabling rapid feature rollouts within biweekly sprints.
- Developed certificate-expiry detection logic in C++, cross-checking X.509 certificates against the system clock at startup; terminals now refuse expired credentials and display a 'Certificate Expired' prompt, protecting transactions for thousands of merchants.
- Refactored legacy code paths with modern C++ best practices (lambda expressions, std::unique_ptr, std::function maps), reducing authorization routine execution time by 15% and eliminating critical memory leaks.
- Authored Python scripts to migrate over 50 SVN repositories to Bitbucket, automating branch mapping and preserving full commit history, reducing migration effort by 40%.
- Triaged and resolved high-severity customer issues (terminal reboots, system crashes) by leading 10+ root-cause analysis sessions—examining logs, reproducing firmware faults, and updating configuration guides—to reduce mean time to resolution by 30%.
- Mentored three junior engineers through internal DevOps and advanced C++ certification programs, co-leading weekly hands-on workshops to share best practices in CI/CD pipelines and modern C++ features.
End of Studies Internship
ReDX (Revolutionary Digital Transformation Technologies)
- Accelerated BFS graph processing by 5.39× on 44 GB seismic datasets by refactoring NextVision’s C++ code to use cugraph::bfs with concurrent multi-source searches and optimized CUDA kernel queues via OpenACC pragmas on an NVIDIA A100 GPU.
- Reduced NextVision environment setup time by 50% (from 40 minutes to 20 minutes) by designing a Docker container pre-installing CUDA 12, cuGraph 0.21, Thrust, and Python 3.10, ensuring reproducible HPC onboarding and eliminating configuration drift.
- Validated algorithmic correctness via byte-for-byte patch comparison, confirming that GPU-accelerated BFS outputs matched CPU results across 120 test graphs (1 GB–44 GB) and maintained 100% fidelity in cluster assignments.
- Collaborated with geophysicists and GIS analysts to identify maximal independent vertex subsets—automating multi‑seed BFS launches—and co-authored an EAGE conference paper that demonstrated a 5× improvement in interpretive throughput.
- Benchmarked FastAPSP versus BFS workloads, projecting a further 3× reduction in compute complexity on large sparse graphs; documented findings to guide future cuGraph integrations once API support becomes available.
Master Degree in Computer Engineering
National School of Engineers of Sfax (ENIS) | GPA (3.63/4.0)
- Master's program focused on advanced topics in computer engineering.
- Gained practical experience in software development, high-performance computing, and research projects.
- Collaborated on various academic and industry-led projects, achieving technical proficiency in a range of technologies.
DevOps Engineer Intern
ReDX (Revolutionary Digital Transformation Technologies)
- Built CI/CD pipelines with GitHub Actions—accelerating releases by 80%—and containerized microservices with Docker and Kubernetes for scalable HPC/AI deployments.
- Architected AWS (EC2, S3, IAM) infrastructure and implemented Prometheus/Grafana monitoring for 99.99% uptime and proactive alerting on performance issues.
- Migrated infrastructure to Terraform as code, improving deployment repeatability and reducing environment drift.
- Automated course-progress tracking and certificate issuance workflows, reducing manual tasks for trainers by 40%.
Full-Stack Developer Intern
Djagora FABLAB
- Developed a Flutter/Dart mobile app for patient monitoring, delivering sub‑second vital‑sign updates for 50+ users.
- Engineered an alert subsystem to send notifications within 5 seconds of critical condition detection, reducing response times by 40%.
- Integrated MongoDB with a Python/Flask backend to securely store clinical data and power RESTful API endpoints for seamless data exchange.
- Collaborated with healthcare professionals to gather requirements and optimize UX, achieving over 50 active users during initial testing.
