Dakar, Senegal · Open to Remote & International Opportunities
I build and optimize backend systems across Go, Java, Python, and TypeScript — from a Go constraint-satisfaction solver optimized 3,500× (36s → under 10ms) to reproducible Docker-based CI/CD platforms and a full-stack LLM output benchmarking tool.
My focus is on algorithms, performance optimization, debugging, and test-driven systems that behave deterministically — backed by strong CI/CD, container, and cloud delivery practices.

Repository: tetris-optimizer
Focus: Go, Algorithms, Backtracking, Performance Optimization, Testing
A high-performance constraint-satisfaction solver that packs tetrominoes into the smallest possible square.
- Reduced solver runtime from 36s to under 10ms (>3,500× speedup) using symmetry breaking, cell-first backtracking DFS, and empty-space pruning.
- Starts from the mathematically minimal board size and prunes search branches that exceed the maximum allowed empty cells.
- Validated correctness with an exhaustive test suite covering standard, complex, and edge-case boards plus negative test cases (invalid formats, disconnected shapes).
Repository: AI_Evaluation_Task_Manager
Focus: TypeScript, NestJS, Prisma, PostgreSQL, React 18, Terraform
A full-stack platform for benchmarking and scoring LLM outputs side-by-side (e.g., Claude vs GPT-4o vs Llama) with strict evaluation workflows.
- Built a modular NestJS REST API with DTO validation, dependency injection, and Swagger/OpenAPI documentation.
- Enforced atomic evaluation submissions with
prisma.$transaction, so a review submission and task state transition can never be left inconsistent. - Stored flexible multi-criteria metrics (Accuracy, Safety, Latency, Conciseness) in PostgreSQL JSONB without schema migration overhead.
- Wrote Terraform-ready AWS infrastructure (VPC, RDS PostgreSQL, App Runner) for reproducible deployment.
Repository: gpu-kernel-benchmark-suite
Focus: C++20, CUDA, Performance Tuning, Profiling
A GPU kernel optimization suite for GEMM workloads across C++20, CUDA, and WebGPU/WGSL.
- Implemented SRAM tiling and float4 SIMD optimizations with Nsight Compute profiling.
- Structured benchmarks for reproducible, comparable performance measurements.
Repository: KubeSecure-GitOps
Focus: AWS EKS, Terraform, Helm, ArgoCD, GitOps
A security-hardened GitOps platform that deploys a Spring Boot API to AWS EKS using Terraform, Helm, ArgoCD, Docker, and Amazon RDS PostgreSQL.
- Built a Kubernetes GitOps workflow with Helm charts and ArgoCD reconciliation.
- Provisioned AWS networking, EKS node groups, and encrypted RDS PostgreSQL with reusable Terraform modules.
- Hardened containers with multi-stage builds, non-root execution, read-only filesystem, and least-privilege NetworkPolicies.
Repository: devsecops_project02
Focus: GitHub Actions, AWS, Terraform, Java, Spring Boot, Docker
A production-inspired CI/CD platform for automated build, test, security, and deployment workflows.
- Built a GitHub Actions pipeline with automated testing, secret scanning, SAST, IaC checks, container scans, DAST, deployment, and teardown.
- Designed a multi-tier AWS architecture with public ALB, private Auto Scaling Groups, and isolated RDS PostgreSQL.
- Implemented OIDC-based keyless AWS authentication and reusable Terraform modules.
Repository: guardianpy
Focus: Python, CLI Design, Policy-as-Code, CI/CD Gating
A local-first CLI tool that detects Dockerfile and Terraform misconfigurations before code reaches CI/CD.
- Built modular scanners for Dockerfile, Terraform, and AWS S3/IAM posture checks.
- Designed POSIX exit codes so the tool acts as a deterministic CI/CD gate.
- Generated Markdown reports and Slack/Discord notifications for developer feedback.
- devsecops_project01 — Ephemeral AWS developer environments with Terraform, GitHub Actions, Prometheus, Grafana, and automated teardown.
- aadsec-public — Local-first audit CLI that runs trusted scanners and turns noisy results into readable reports.
