I have worked exclusively in COBOL programming for the past 5 years (my complete work experience), having gained significant work experience in legacy modernization projects for major investment banks, designing their IT platforms for asset management, credit/debit card and wealth management tracks. I also have 2 years of experience in leading teams of size 5 for the same projects that received immense appreciation from the clients for the quality and timeliness of the prject delivery
Having worked in SDLC frameworks, I would, broadly speaking, apply the same the concept in breaking down your proposal into manageable stages such analysis, design & development, testing and finally delivery/sign-off, measuring the outcome at every stage. Finally, I would give this project my utmost attention and would guarantee that my work will be off the highest quality.
