Joshua Peter

• Architected production AI (Telegram/WhatsApp) managing full lifecycles via LangGraph, FastAPI & Gemini 2.0 (sub-5s latency, >99% accuracy). • Engineered dual-memory RAG (Qdrant, BM25) & secured auth via passwordless OTP/JWT. • Provisioned hardened Linux VPS (Nginx, Fail2Ban) & containerized stack (Docker, Postgres, Redis). • Built zero-downtime CI/CD pipelines (GitHub Actions) with multi-worker Gunicorn/Redis locking.

• Customized YOLOv7 for ADAS (high/low beams, pedestrians) implementing anchor box tuning, sample weighting & custom training hooks for stability. • Curated and refined training datasets using Azure Custom Vision to improve detection accuracy. • Processed FleetEdge telemetry for driver behavior analysis; engineered features for smoothness scoring and built real-time FastAPI pipelines. • Collaborated with cross-functional teams to ensure model deployment-readiness.

• Refactored scalable backend (NestJS, TypeScript, Prisma, Postgres) & led MVP data modeling/product definition. • Managed AWS Cloud (EC2, RDS, S3, SES) & deployed Dockerized services via CI/CD pipelines. • Mitigated bot attacks by analyzing RDS logs/implementing rate limiting & built RBAC for secure multi-role access. • Facilitated React integration via strict API contracts & maintained automated Postman test suites. • Directly advised CEO on product strategy & developer retention.

• Developed data manipulation and visualization skills using NumPy, Pandas, Matplotlib, and Seaborn. • Gained experience in NLP, machine learning (regression, clustering), Trees, deep learning (ANN, CNN, RNN, bi-LSTM), and integrated solutions with OpenCV. • Contributed to real-world projects and delivered results through regular assessments and hands-on tasks. • Gained hands-on experience with tools and platforms such as Streamlit, Excel, Power BI, and SQL.

(Transitional Period & International Relocation) • Maintained full-time roles in high-security logistics (Dublin Airport) & manufacturing, adhering to strict Airside/HACCP protocols during 12-hour shifts. • Demonstrated grit by balancing physical labor with independent upskilling (Python/Web Design) and managing complex international visa/academic paperwork. • Proved adaptability and operational reliability in high-pressure environments before returning to tech.

• Delivered critical loan app migration (Excel/VB to C#/.NET/Bootstrap) & initial release despite abrupt handoff/limited docs. • Resolved full-stack defects by tracing logic across C# controllers, UI handlers & large-scale SQL Server stored procedures. • Streamlined feedback loops using Jira to coordinate logic changes between testers, analysts & leads. • Aligned technical implementation with business needs (SFS data), ensuring accurate financial workflows for underwriters.

• Developed MS SQL Server databases for US real estate firms; performed ETL via RETS/RESO APIs, PowerShell & SSIS. • Automated workflows using SQL Server Agent & generated complex reporting via SSRS/XML. • Optimized query performance, resolved deadlocks & handled technical support tickets in Jira. • Mentored new hires on company workflows & collaborated with frontend teams to meet strict project deadlines.

• Completed an intensive program focused on examining, interpreting, and leveraging large datasets, and enabling intelligent decision-making systems. • Gained expertise in advanced data analytics, machine learning, and artificial intelligence, with an emphasis on practical application and real-world projects. Core Modules: Natural Language Processing, Computer Vision, Data Pre-Processing, Machine Learning, Deep Learning, Hadoop, Apache Spark, Amazon AWS, Linux, Kafka Confluent, and KSQL.

• Acquired foundational knowledge in computer science and engineering principles, focusing on the design, development, and analysis of computing solutions. • Developed strong problem-solving and analytical skills, applying software engineering methodologies for robust system development. • Prepared to adapt to emerging information and communication technologies and innovate solutions for complex challenges.
