I develop my own custom designed solutions for each problem, often using an API and/or libraries I have developed erstwhile, so variants or similarities on any of them cannot be found elsewhere.
I deliver fully developed products as per the project specification. Timing is of highest importance, we can discuss other factors as per individual basis. Terms and payment arrangements are to be discussed prior to the commencement of the project.
Following listed are my expertise and typical projects I routinely do:
Programming languages:
C++ and C-like languages,
Haskell,
JAVA,
Python,
Scala,
Common Lisp,
PHP,
Perl
Special Topics:
NumPy, Statistics, Scipy, Matplotlib, Natural Language Processing ( NLTK, SpaCy ), Data Structures & Algorithms, API development, Software Design and Engineering plans in UML and Project specifications and documentation.
Computer Architecture:
Assembly language ( X86, X86_64, RISC )
Verilog
System Programming & Networking:
Bash Shell Scripting,
Power Shell,
Linux / UNIX Systems Programming, Mac OSX, Windows API
Threading and Kernel Development
App Development:
iOS and Android App Development.
SDK based and Native Developed Apps.
Web Development and Databases:
Most webapps/sites can be developed with JavaScript, CSS3 and HTML5, however, depending on your expected traffic and need for performance and should it eventually be scalable and suitable for migration, it must be fitted with a sturdy backend.
Webframeworks:
web2py, Django, Node.js, jQuery, ( almost all JavaScript Libraries for that matter, AngularJS, Vue, ReactJS most are markedly similar)
Databases:
SQL,
MySQL,
PostgreSQL,
