Professional Summary

Over ** years of experience in information

technology including desktop, mobile and web

software development, systems administration and

database programming. My experience including work

on manufacturing and planning applications and

enterprise resource planning systems in the .Net

framework furthered by exposure to commercialization

has given me a unique perspective in information

technology.

One of my most important strengths is the ability to

tackle issues in environments that I have very

little to no knowledge of. I believe that my

diverse experience in many facets of the computing

industry was the determinant factor in shortening

the learning curve.

Professional Experience

. Company Profile - Advanis Inc. utilizes digital

technology and the internet to provide high

quality market research data to a wide range of

clients. Advanis has offices in Alberta, British

Columbia and Ontario.

. Project Highlights - My assignments include

implementing a mobile device survey API and

maintaining an online reporting environment.

. Planning - The company adopts a ticketing system

to assign and monitor tasks.

. Development -Test driven development is adopted

primarily using unit tests in Python and pgTAP

(for PostgreSQL) in a multi-tiered SOA. HTTP,

XML-RPC and SIP protocols are used for

communicating between tiers as well as external

entities. Mercurial is used for source code

version control.

. Technical environment - Unix like systems

including Mac OS, Python, PostgreSQL, PHP, HTML,

Mercurial, Virtual Environment (Python) and Java

Script.

. Company Profile - Digital Time Capture provides

time tracking software and customized

applications to the construction and oil and gas

industries. A typical client is a company with

annual revenues of $50 million and above.

. Project Highlights - I was assigned mainly to the

data migration part of a legacy COM application

to.Net that is built on MVP, LINQ and WCF which

is a type of an ASP.Net application. In

addition, I also met with clients to revise

existing functional specs. The legacy OLE data

is first converted into SQL that forms the

baseline and further processed to shape it to the

newly developed data model. In departing from

COM and moving towards .Net, a variety of .Net

methodologies such as hosted applications,

concurrency control and distributed transactions,

and side by side and dynamically versioned

assemblies were explored to be utilized as

applicable.

. Planning - The team thoroughly went over the

functional requirements, specifications and

database schemas and has mapped out a plan early

in the project. A typical day starts with a

morning update of the most recent database

compilation informing the updates and issues.

The developers typically touch-base with each

other near the end of the day to coordinate and

maintain optimal work flow.

. Development - Development tends to be in short to

medium cycles due to the coordinated development

of the frontend and the backend of the new system

in .Net where the frontend developer updates the

source code and informs requirements to the

backend developer.

. Technical environment - OOP, N-tier, ASP.Net,

MVP,WCF, ASP.Net, VB.Net, LINQ, XML, SQL Server

2012, DBMS, Team Foundation Server, Windows 7 and

8, and DevExpress.

. Company Profile - The company provides a scaled

down ERP system, referred to as an inventory

management system, to the oil and gas industry.

It operates in coordination with a sister company

called Advance-Tek where one of their

specializations is in the Scientific Research and

Experimental Development (SRED) program.

. Project Highlights - The architecture strictly

adheres to the model view presenter (MVP)

topography in view of future scalability, and

exclusively uses LINQ for database access. I

went into the project knowing next to nothing

about the business or the technicalities, but,

for example, was able to provide solutions to

problems on DevExpress controls that their tech

support team was unable to resolve. I was

responsible for the entire implementation and

integration of a time tracking module with a

conjoined grid and scheduler interface into the

system and had also made significant

contributions in the development of a project

management module including the recursive task

exclusion, and integration of SRED evaluation

criteria. I have also participated in the

planning of asset tracking and fleet management

modules, and gathering user requirements.

. Planning - A typical day starts with a morning

meeting to plan activities and discuss business

and architectural issues that need to be aware of

as the business analysts and developers proceed

with their work.

. Development - Development tends to be in short

cycles due to the business requirements. Tasks

are divided among developers and coordinated

throughout the process to make sure the coding

conforms to the company standards and the

structure adheres to the MVP architecture. The

application suite was developed in VB.Net and

SQL.

. Testing - Testing and code consolidation is

carried out before a typical deployment. The

staging database server is first updated by all

developers that had made a change to their

schemas. At the same time, all changes made to

the code are merged onto the TFS, followed by

testing and code reviews where in a typical

testing scenario a developer cross tests a

different developer's code.

. Deployment - The final prerelease version of code

is tested again before deployment. The

application goes through an obfuscation process

before launching it onto the production server.

. Technical environment - OOP, N-tier, MVP,

ASP.Net, VB.Net, LINQ, SQL Server 2012, SSRS,

Team Foundation Server, Windows 7 and 8, and

DevExpress

. Chrysler Canada -Show floor IT support.

. IBM Canada - Corporate takeover desktop rollout.

. Enbridge - Corporate IT restructuring desktop

move.

. Project Highlights - Designed and developed a one-

handed touch screen keyboard that would allow 8

mm wide keys on and a 40 mm wide device while

delivering one keystroke per character, and a

more accurate word completion system that is

algorithmically deterministic. A web based

crawler that periodically crawls websites and

index the words and their frequencies translated

into rankings in the word completion system was

also developed in C#, ASP.Net and SQL.

. Development - The components for the keyboard and

word completion system were developed in C/C++

which is unmanaged (native) code in contrast to

C# or VB.Net which are managed code. As a

consequence, many of the features taken for

granted in the .Net environment had to be coded

from scratch.

. Testing - Unlike managed code, unmanaged code

doesn't lend itself well to testing tools such as

NUnit or Visual Studio 2008 testing features. As

a result, I ended up rigging a custom setup for

testing purposes, but even then tests involving

the Windows message loop and the GUI were a major

challenge.

. Technical environment - OOP, N-tier, C, C++,

C#.Net, ASP.Net, DBMS, MySQL and SQL Server.

. Project Highlights - Designed and developed an

automated stats retrieval and compilation system

for more than 80 web sites maintained by the

foundation, and substantially reduced the web

server down time to less than 1% per year by use

of automated reporting mechanisms developed in

house

. Web applications - I started working with Web

based ASP.Net applications in VB.Net and SQL

after I joined the Heritage Community Foundation.

The foundation maintains more than 80 websites

and part of my duties involves maintaining a web

crawler that crawls those websites and indexes

the search terms and links in a SQL database.

JavaScript was used from time to time for other

client side processing such as ordering

publications for the foundation.

. Technical environment - Windows and Cobalt

(Linux) servers, Windows XP desktops, OOP, N-

tier, VB.Net, ASP.Net, DBMS, SQL, PHP, CSS, HTML,

XML, GIF, DreamWeaver 8, Adobe ActionScript,

Adobe Creative Suite and Shell and Java scripts.

. Project Highlights - Designed and developed a

Virtual Keypad Input Device that features a

highly space efficient interface. A simulator

was built using VB 6.0, and models and animations

were developed in TurboCAD and AnimationLab.

. Technical environment - VB 6.0, HTML, C#,

ASP.Net, TurboCAD and AnimationLab.

. Company Profile - Micron is a semiconductor

manufacturer that makes memory chips. The

company heavily relies on automation in its

planning and fabrication processes.

. Project Highlights - My duty at Micron involved

the maintenance and support of a manufacturing

and planning software suite that is used to

create plans 3-5 years into the future and feeds

the high level instructions further down into the

fabrication automation systems by working closely

with internal clients. The application suite was

developed using VB 6.0 with a SyBase backend.

Initiates were also taken to migrate the

application suite to the C# /VB in .Net. Due to

the mission critical nature of the application,

rollback mechanisms were incorporated into the

system to allow recovering from the release of a

faulty manufacturing plan. I was able to bring

down the error rate to a trickle during my

assignment at Micron.

. Development -Development tends to be from medium

to long cycles as the majority of changes require

careful planning to prevent destabilizing the

application suite due to its mission critical

nature. RUP using Rational Rose was introduced

in the later stages to keep up with the

increasing complexity of the application suite.

ADO, LDAP and single sign-on access were

incorporated into the middleware component.

. Deployment - A deployment is typically preceded

by an alpha release, and a beta releases

evaluated by the clients. The changes are

deployed to the staging server and later to the

production server followed by a final evaluation.

Micron adopts full cycle application management.

. Troubleshooting - Aggressive expansion of

features to keep up with the demands of the

planning needs for the highly competitive market

conditions and advancing machinery at the

fabrication plants may have introduced more bugs

into the system over time. The lack of

dedicating more resources and regression testing

towards tackling the growing error rate may have

also compounded the problem. I gravitated

towards troubleshooting tasks due to a variety of

reasons but managed to substantially reduce the

error rate during my assignment at Micron.

. Technical environment -VB 6.0, SyBase, DBMS,

HTML, OOP, N-tier, C#.Net, VB.Net, ASP.Net, XML,

CVS, RUP, UML, LDAP, Change Management, Citrix,

Documentum and Rational Rose.
