About the Author

About the Developer:

Engr. Roberto M. Recamunda is a Civil Engineer and Jr Geodetic Engineer (4th Place 1984). He finished BS Civil Engineering from Divine Word College of Legazpi and BS Geodetic Engineering from University of Northeastern Philippines, Iriga City.

He received his first Casio Programmable calculator fx502P in 1983 when he entered the Bureau of Lands, Surveys Division in Legazpi City and discovered its programming capability. He developed simple routines in it and later coded programs for Casio fx-602P model. He basically learned programming concepts by reading the reference manual of said model. With the survey algorithms he developed he was able to upgrade them to the succeeding casio models. He was introduced to basic programming with the model Fx702P.

Dir. Flor Pelayo recommended his programs to various regional offices and conducted series of lectures while Engr. Herminio Pada introduced him to GEP. For his contributions he was awarded the Most Outstanding Employee of Bureau of Lands Region V in 1985 while GEP Regional Divisions awarded him Plaques of Appreciation. He was sent to the Bureau of Lands central office in Binondo where he was introduced to IBM S370 mainframe computers using COBOL and Fortran languages.

With the advent of Personal computers he was able to port his programs to Apple IIe and Casio PC. In 1985 his office bought the first 3 IBM compatible PCs where he developed the Land Survey programs using MS Basic compiler. He was introduced by Engr. Boyet Lucero to the sideshots concept enabling him to integrate all survey computations into a common file. He further introduced AutoCad portability and Contouring capability to some modules. He piloted the Land Informations and Database archiving using Foxpro and AutoCAD.

He further studied GIS concepts using PC Arc Info in DENR Cebu City. Although he self studied programming he was able to pass the Systems Analyst Proficiency Exam conducted by National Computer Center in 1994. While teaching various computer subjects after office hours at Computer Arts and Technology School – Legazpi he continued to be consultant to different businesses and private GEs every weekend.

While at the Planning Division of DENR V he completed the DENR Region V 10 Year Information Systems Plan used as basis for computer equipments and software procurements. He resigned in 1995 to join his wife Sonia Lim to form Big Shots Party Sales as Tupperware distributor for the next 13 years. He stored his program manuscripts in a Tupperware Giant case where it was miraculously saved from Typhoon Reming and the ensuing flood that engulfed Albay in 2006. From the saved algorithm he was able to recode the land Survey Programs for Casio fx-9860G and named it Big Shots.

His current project now is the “ONE CALCULATOR ONE STUDENT” project aimed at providing calculators to far flung elementary and high school students and teaching them programming for scientific and engineering applications using the various casio models.
