John was outstanding to work with. He was extremely fast, knowledgeable, and skilled. He completed a WordPress project with a Custom Post Type, filtering, sorting, and searching, Advanced Custom Fields, and detailed CSS with great precision and incredible turnaround. He was very helpful in understanding all aspects and his communication was excellent. I would highly recommend him.

I have worked wit John Leskas twice now and I am very excited. He answers quickly, helps with great suggestions so further development is easier to implement, has a good sense of humor, works fast and delivers and...... also tests his work well across platforms and browsers. Whats not to love. I give him my highest recommendation.
