    As a seasoned IT professional with 10 years of working experience, I took a journey along with the industry's progression and always refreshed my skills to keep up with the trend. Starting my career as an application developer, I moved to full stack and back end development then recently moved again to machine learning. What's unchanged in the changing time is the passion for problem solving and continuous learning. Whether the task is translating ambiguous business goals to technical design and execution, or doing data analysis to guide decision making, or creating and executing a roadmap for the team, I had experience and did them well. Whether it's a 0 to 1 project (i.e rapid prototyping MVP) or one to many (high availability service) projects, I have first hand experience. This is not to mention various team roles like scrum master, component lead or retrospective coordinator I did in agile development teams.

Appropriate manners are required – rudeness is prohibited. ★ Don’t act like an amateur. ★ No lateness to meetings. ★ If you need something done faster, or a change in scope, let me know – before we get started. ★ I commit to honesty & directness. Our job is to improve, and it’s best done with hard truth from a second set of eyes. ★ If I can add value, I will speak up and give advice based on my experience & what I’ve seen that works well. ★ You’re always free to take my advice to heart, or ignore me completely. ★ My rates are neither the cheapest, nor the most expensive - but I ensure that the value my clients receive as a result of working with me, far exceeds what they have paid. ★ One cook in the kitchen please: Your team’s comments must pass through a single point of contact on your side. ★ Perfection takes time. Please be patient. ★ If you don’t love your end result please let me know ASAP. I will deliver one that you do. ★ I am in the business of exceeding your expectations.
