Dear Valued Employer, My name is Martin and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for a hardware engineer who would be capable of designing a custom coin cell battery charger as per your requirements. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Proposal for solution 3. Schematic drafts 4. Component library creation 4.1 Schematic symbol library creation 4.2 Footprint library creation 5. Schematic drawing 6. Review of final schematic drawing 7. Layout design 7.1 Components placement and arrangement 7.2 Review of proposed layout design arrangement 7.3 Components routing 7.4 Review of final layout design 8. Design rule check 9. Verification and validation 10. Production files (GERBER, NC DRILL, STEP, BOM, ASM, PICK & PLACE, SCH, 2D mechanical drawing) Your project will be carried out on Altium Designer. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for your time.

Hi,you will also need to provide more information on the battery type ,voltage as this will enable me design the charging circuitry, I will include a type c USB charging port so that you can use your mobile phone charger as a charger I will also include an LCD interface for you to view the charging status so you will know when it is full. I will also design a pcb for this project and provide you with all the necessary files. I am available for further discussion on this project. Thank you.

I have strong knowledge of integrated circuits designed specifically to this purpose - charging li-ion cells. I its your goal to have a faesible solution of circuit for changing this cells i can do your task. Or if you decide to go with ready made modules for charging we can do this also. It depends on number of cells , current capacity, input voltage etc...
