Key Highlights

Long Hoang – Leveling up at work

• Mindset and habits for continuous growth in a tech career
• Practical ways to improve skills, visibility, and impact in the workplace
• Lessons from an FCAJ Ambassador on staying motivated and progressing step by step

Thinh Nguyen – AI hallucination

• What AI hallucination means when models generate plausible but incorrect information
• Common causes and risks when relying on AI in DevOps and engineering workflows
• Tips to verify outputs, prompt more effectively, and use AI as a helper—not a single source of truth

Khang Nguyen – Job hunting and office survival skills

• How to prepare for interviews and present yourself clearly to employers
• Soft skills and professional habits that help you succeed after joining a company
• Real-world advice from a Solution Architect on adapting to team culture and office expectations

Thao Nguyen Phuong – Vibecoding with BMAD

• Introduction to vibecoding — a flow-focused way of building with AI-assisted development
• Overview of the BMAD method and how its phases structure planning, building, and iteration
• Reference: BMAD Method documentation

Key Takeaways

• Career growth is intentional: set goals, learn consistently, and seek feedback like Long Hoang emphasized
• When using AI tools, watch for hallucination and always cross-check critical facts and commands (Thinh Nguyen)
• Job search and onboarding go smoother with preparation, communication, and professionalism (Khang Nguyen)
• Structured methods like BMAD can make AI-assisted coding more productive and less chaotic (Thao Nguyen Phuong)

Applying to Work

• Build a personal level-up plan (skills, certifications, side projects) and review it each month
• Add a verification step whenever AI generates code, configs, or documentation before you commit or deploy
• Refine CV, portfolio, and interview stories using job-hunting tips from the session
• Try BMAD on a small personal or internship task and document what worked in your workflow

Event Experience

Attending “Community Day FCAJ HCM” was extremely valuable, connecting me with the FCAJ community in Ho Chi Minh City and learning from practitioners across cloud, DevOps, and AWS programs. Key experiences included:

Learning from the organizing team

• Khang Nguyen, Thinh Nguyen, Long Hoang, and Thao Nguyen Phuong helped make the event happen and shared perspectives from solution architecture, DevOps, and cloud engineering.
• Sessions and discussions reinforced practical skills and community practices relevant to FCAJ and FCJ members.

Session highlights

• Long Hoang inspired a clearer view of how to grow at work instead of waiting passively for opportunities.
• Thinh Nguyen helped me understand AI hallucination and why verification matters in DevOps and daily coding.
• Khang Nguyen gave practical guidance on interviews, office culture, and habits that help new graduates fit in faster.
• Thao Nguyen Phuong introduced vibecoding with BMAD, opening a structured path to explore docs.bmad-method.org.

Networking and discussions

• Met FCAJ/FCJ members, exchanged experiences about internships, AWS learning paths, and community activities.
• Open Q&A after each talk made it easy to ask follow-up questions about career and AI usage.

Lessons learned

• Leveling up is a long-term process: small, consistent improvements beat one-off effort.
• Use AI with critical thinking; hallucinations are a real risk for configs, commands, and explanations.
• Soft skills matter as much as technical skills when applying for jobs and working in a team.
• A method like BMAD can turn “vibecoding” from random prompting into a more repeatable workflow.
