• Drive problem‑solving efforts, finding simple, effective solutions to complex challenges.

Coding & Design

• Design and develop asynchronous web applications using Python and FastAPI.
• Apply and enforce SOLID principles, Separation of Concerns, and Dependency Injection (IoC) for modular, testable code.
• Implement Hexagonal Architecture (Ports & Adapters), and leverage design patterns such as Factory, Repository, and Decorator to ensure clean, scalable solutions.
• Group and lead best practices in coding standards, code organization, and technical documentation.

Data Modeling & Extraction

• Design and optimize data models and structures based on evolving business requirements.
• Identify data patterns, perform data extraction, and implement efficient data access and transformation strategies.
• Collaborate with stakeholders to translate business needs into robust, scalable data solutions.

Production Systems & Observability

• Lead production deployments and ensure high system reliability.
• Implement observability practices, including custom metrics, logging, monitoring, and alerting.
• Debug and resolve complex production issues, driving root cause analysis and continuous improvement.
• Ensure robust exception management and proactive handling of system failures.

Collaboration & Communication

• Work cross‑functionally with product managers, designers, and other engineers to deliver impactful technology solutions.
• Communicate technical concepts clearly to both technical and non‑technical stakeholders.
• Foster a culture of ownership, accountability, and continuous learning within the team.

• Bachelor’s or Master’s degree in Computer Science or related field, or equivalent experience.
• 6+ years of professional experience in Python web application development, with at least 2 years in a technical leadership or lead engineer role.
• Advanced proficiency in Python, FastAPI (or similar frameworks), and asynchronous programming.
• Proven experience in data modeling, designing data structures, and extracting actionable insights from data.
• Track record of solving complex problems with simple, maintainable solutions while owning project delivery.
• Demonstrated expertise in microservices & hexagonal architecture, ensuring data consistency across distributed services and applying design patterns such as Factory, Repository, and Decorator.
• Hands‑on experience with relational databases (PostgreSQL, MySQL, etc.) and ORMs.
• Production experience with deployment, observability (metrics, logging, monitoring), alerting, and debugging.
• Familiarity with CI/CD pipelines, containerization (Docker/Kubernetes), and cloud platforms (Azure, AWS, GCP).
• Excellent communication, mentorship, and team leadership skills.

• Experience with frontend frameworks (React, Angular).
• Familiarity with event‑driven and distributed systems.
• Experience with advanced analytics, machine learning, or big data processing.
• Exposure to modern observability tools (Prometheus, Grafana, Datadog, etc.).

• A technical leader passionate about engineering excellence, data‑driven solutions, and team success.
• Skilled at breaking down complex problems and guiding teams toward practical, elegant solutions.
• Committed to production reliability, observability, and continuous improvement.
• Effective communicator and mentor, fostering a collaborative and innovative team environment.
