Technical Direction
Architecture & technology
I take ownership of technical decisions across projects, from defining application architecture to evaluating technologies and establishing development approaches.
- Define application architecture.
- Evaluate and select technologies.
- Establish technical approaches and patterns.
- Break complex requirements into technical solutions.
- Identify technical risks and trade-offs.
- Improve and restructure existing architectures.
Team Coordination
Coordinating a team of ~5 developers
I coordinate a small development team, helping turn project requirements into clear, actionable work.
- Assign tasks based on project priorities and individual strengths.
- Break down larger requirements into manageable pieces.
- Track progress and identify blockers.
- Review implementations.
- Provide technical guidance when needed.
- Help less experienced developers solve problems independently.
- Maintain consistency across the codebase.
Code Review & Quality
Quality through collaboration
Code review is not only about finding mistakes. I use it as a way to maintain quality, share knowledge and help the team grow.
- Code reviews.
- Architectural reviews.
- Technical feedback.
- Refactoring decisions.
- Consistency and maintainability.
- Knowledge sharing.
Project Planning
From requirements to execution
I participate in project planning from the early stages, helping translate business requirements into technical tasks and realistic development plans.
Requirements → Scope → Architecture → Tasks → Development → Review → Delivery
- Requirements gathering.
- Task breakdown.
- Prioritization.
- Technical planning.
- Estimation.
- Coordination.
- Delivery.
Client Communication
Bridging technical and business needs
I regularly work directly with clients to understand their needs, discuss requirements and present technical solutions.
- Understand the actual business problem.
- Ask the right technical questions.
- Translate business requirements into technical requirements.
- Explain technical concepts in accessible language.
- Present proposed solutions.
- Gather feedback and iterate on the solution.
Mentoring
Helping developers grow
I've helped onboard and guide less experienced developers, giving them ownership of tasks while providing technical support when needed.
- Task assignment.
- Technical guidance.
- Code review.
- Feedback.
- Problem solving.
- Encouraging independent thinking.
Understand
Understand the problem.
Define
Define the right solution.
Architect
Give the team clarity.
Build
Build with purpose.
Review
Review and improve.
Deliver
Deliver together.
Intern
Starting pointJoined as an intern, learning the codebase and shipping first features under guidance.
- Built features across the stack under senior guidance.
- Learned the codebase, conventions and review process.
Full Stack Developer
Full-time roleConverted to a full-time role, taking on increasingly independent ownership of features.
- Owned features end to end, from requirements to deployment.
- Started contributing to architecture and technical decisions.
- Worked mainly with Node.js across backend and frontend.
Technical Lead / Lead Full Stack & AI Engineer
CurrentBecame the technical reference for the department: deciding architecture and stack, coordinating the team, and working directly with clients.
- Define architecture and technology decisions for projects.
- Coordinate ~5 developers/interns — task assignment, code review, mentoring.
- Lead development of AI-powered features, including an on-premise AI system for a client.
- Participate in project planning and technical roadmap decisions.
- Speak directly with clients to gather requirements and present solutions.
About Me
I'm a Full Stack & AI Engineer with 3 years of professional experience, currently working across software engineering, AI, product and UX/UI.
I started my career as an intern and gradually took on broader responsibilities — from building features to defining architectures, making technical decisions, coordinating developers and working directly with clients.
Today, I work across the full product lifecycle: understanding the problem, shaping the solution, designing the experience, building the product and helping the team bring it to life.
What I enjoy most is working on problems where there isn't an obvious answer.
I like understanding why something needs to be built before thinking about how to build it. That means talking to users and clients, challenging requirements, designing workflows, choosing the right technical approach and turning complex systems into simple experiences.
My work sits somewhere between engineering, AI, product and design — and I enjoy moving between those disciplines.
